One of the best lectures in paleontology. Dr. Green's presentation was exceptional. He explained difficult concepts with clarity and precision. He is a talented teacher !!!

The Basques of Northern Spain are LIVING WALKING TALKING NEANDERTHALS. As PROVEN by British Medical Science over 10 years ago. These people exhibit as high as 75% Neanderthal DNA. Have RESUS NEGATIVE Blood, the KNOWN Neanderthal blood type, which does NOT work in humans properly & causes medical issues. Indeed the Basque language with NO connection to ANY Human language is itself the Neaderthal language. So Professor Green, giving the talk, must have spent the last 10 years living on a lost Pacific island, as virtually everyone else in the Scientific community is aware of that Bombshell 10-12 years ago !!!!!

My grandma said put your head between my legs and kiss and lick me there I did as grandma said then momma spread my. Butt cheeks apart and kissed and licked my butt hole. We did this for years
I find your subject matter fascinating. I didn’t study any of this in University, but just stumbled on it while scrolling through You Tube about six months ago. Now i cant get enough of it. I look for new videos every night. I am particularly fascinated by Neanderthals.
While visiting France as a child there was a shopkeeper in Strasbourg with the most pronounced brow ridge I have ever seen on a human. He also had a head of enviable coarse hair and fingers twice as thick as my dad's. I knew then and there where the Neanderthals had gone, nowhere they were still here.
Not enough facts ! As British Medical Science proved and announced that the Basques of Northern Spain are LIVING WALKING TALKING NEANDERTHALS, OVER 10 YEARS AGO !!! Indeed the Basques have as much as 75% Neanderthal DNA and of course have RESUS NEGATIVE Blood the known Neanderthal Blood group which does NOT work in Humans properly & causes medical issues particularly in women. And we now even know that the weird Basque Language which has NO connection to any Human Language has to be the remnants of the Neanderthal Language. All of the above was published in numerous Medical Science journals over 10 years ago !!!! So the Professor giving this talk, has either been living on a deserted island for over 10 years, or he's stone deaf, or just plain IGNORANT !!!
LOVED the joke at the very end as an answer to the "missing link" question. Also, the last couple of topics relating to autism and the other disease which hinted at genetic throw-back possibilities. Amazing content.
autism is about diet also diet of mother in pregnancy toxic things interfere with natural expression of genes as well as hormonal devolvement and we consume loads of toxic things daily nearly nothing in shop is fresh natural and truly organic as found originally in nature where we evolved you can't expect human to grow into human living in since thousands years inhumane conditions
My dude, not only minds are dynamical systems ( as Lenny da Vinci noted of the heart, "never stopping unless forever") but also your very brains are, with neurons CONSTANTLY budding new dendrites, with astrocytes and other monitors of USE nipping off the unused of that efficient energy consumer (as thus, YES, we are all brilliant teenagers consuming refrigerator contents in quantities distressing to economizing mammas). (and one of the astonishing artists who helped me, also observed this: " anything you do contains the universe", meaning all that you have known, do, and can, know. But we are in reality pretty limited to our experience, which we often erroneously interpret, and in creating useful personal heuristics, often distill too much reality out, replacing it what Eric von Zipper, yet another famous philosopher, called "An Army of Stupids" Your mind IS change. Were it static in any way, you would be a fossil before your time.
You are as smart as anyone else! The lecturer has been closely studying his material, all day and all night, for thirty years. He has had hundreds - possibly thousands - of discussions or brief exchanges with expert colleagues and teachers since adolescence. Try re-listening to short sections of that lecture over a few weeks. And do a little parallel reading of introductory texts on anthropology. Even read a few random paragraphs of social history and political theory and psychology and economics and linguistics and philosophy. Ignore any points which are obscure. Five minutes per day at breakfast - for 12 months. Read some of the great essayists - such as Charles Lamb, Seneca, Richard Steele, Carlyle’s, “Past and Present”, Plato’s ‘Gorgias’, around Sections 300 to 494!

In the 2011 CARTA video, Ed made it clear that the "12.7" percent was measuring chimp-like DNA in Neanderthal. It would be interesting if any archaic humans (e.g. Ust-Ishim) had any such chimp-like DNA, which would verify the molecular clock theory.
Yes, he mixed that up with the light skin gene which had to do with vitamin D in northern latitudes. According to Johannes Krause (whom the lecturer probably knows or has met during his time in Leipzig), the lactase thing only became prevalent during the middle ages when cows were bred to give more milk.
@@johannageisel5390 famous story from Homer's Odyssey describes Odysseus' encounter with the cyclops Polyphemus who is milking goats and making cheese. The story, to my understanding, predates the middle ages by about 2000 years and suggests adult humans were making lactase.
@@IbnFarteen In cheese and other processed milk products (yoghurt etc.) the lactose content is usually lower, because bacteria turn the lactose into other substances. That's why people with mild lactose intolerance have no trouble eating cheese and yoghurt, but might get problems when drinking milk. But yes, the ability to make lactase as an adult at least in small amounts is probably older. But it spread to most of the adult European populace only relatively recently. It was rarer before.
@@wooddoc5956 It was a couple of years ago, so I'm not certain anymore. I may misremember it or misunderstood him. Maybe he was talking about something like the latest uptick in lactose tolerance in Europe. Or he actually said "Middle Bronze Age" and I just misheard it completely. I looked around the internet and couldn't find anything that said "Middle Ages", so I admit I probably got that wrong. And it seems that generally the development of lactase persistency took a while to spread. "By mapping patterns of milk use over the last 9,000 years, probing the UK Biobank, and combining ancient DNA, radiocarbon, and archaeological data using new computer modelling techniques, the team were able to show that the lactase persistence genetic trait was not common until around 1,000 BC, nearly 4,000 years after it was first detected around 4,700-4,600 BC." - From "Famine and disease drove the evolution of lactose tolerance in Europe" UCL News

A pack of outdated Garbage ! As over 10 years ago numerous Medical Science Journals reported the amazing tests carried out on the Basques in Northern Spain, by BRITISH MEDICAL SCIENCE. Which revealled the Basques are LIVING WALKING TALKING NEANDERTHALS, with up to 75% Neanderthal DNA. "Resus Negative" NEANDERTHAL BLOOD, and even their weird Language has to be the remnants of the Neandertal Language.

52:20 Our phase of being haploids is indeed long: from near our mother's conception (she is born with our egg) until fertilization. Many, many people have been haploids longer than they've been diploids, given the fact that a huge number of humans (especially in the fastest-growing countries) are younger than their mom was at conception.
Graph 1:00:35 matches the Summer (northern) and Winter (southern) positions of the intertropical convergence zone. Possibly the sea barrier prevented Japan from being involved. Ancient rainfall might have been significant.
I also enjoyed this detailed discussion of anthropological history - and the underlying suggestion of the alternative ways in which the anthropological rhetoric may be used to excuse or conceal modern conservative attitudes. I would only add, Mr Lerie2010able, that you ought not to depreciate the worth of your judgment about human worth. There is nothing to be gained by using expressions such as “even I could understand”.
Starting at around 52:00, the discussion of gene shuffling from grandparents to current generation, seems different from what I've seen in usual layman - i.e., me - discussions. Are there good sources online that explain this in greater detail? Thanks.
I've seen stuff on sites like Ancestry's genetic portion of their site, and I also believe 23 & Me, as well. I recall one article that explained why one sister of (3 or 4) didn't inherit any of one portion of the family's ancestry (Irish, if memory serves) that the other sisters had varying percentages, up to something like 75%, showing in their results. Perhaps you could investigate there for some answers to your questions. 🙂
@jimvj5897 David Reich (whom he mentions early in the video) describes it similarly, but it's not really that accurate to describe it that way in my opinion because we obviously get our genes from our parents. What he means is that we get very long segments that are unchanged from our grandparents (via our parents). These segments can be millions of base-pairs long. The important thing is that if you look at two people's DNA and they have very long segments that are identical (in areas of the DNA that are not normally identical) you can conclude that they had a common ancestor within a few generations. The shorter those segments are, the further back the common ancestor is.
@@gastronomist Thanks. Yes, he's not completely accurate, but I would like to find a readable (non-biochemist) account of what really happens during the formation of an egg or a sperm. I have not found one yet. Appreciate the help.
47:10 - How the Denisova DNA got all the way from Siberia to Papua New Guinea, whilst skipping India/Indonesia is fascinating. Unless those areas were invaded/settled by new migrant populations ofc, which would make sense.
Bear in mind the Siberian sample is ancient, and the PNGuinea samples are where they find the highest traces in modern humans today. So Denisovans could have been all across Asia + India in antiquity, then some sort of regional disaster - perhaps a volcano, asteroid impact, plague or disease - completely wiped the population out with the exception of the the southern islands. Then humans moved in and repopulated the area, interbreeding with the small remaining Denisovans population that still existed only in those southern islands before that branch went extinct. This sort of thing has happened in history numerous times. @12,000 years ago, something happened that vanished the Clovis culture people from all of the North America. Their DNA only shows up in Central and South American populations today. They used to be across all the Americas but the decimation was regional to the northern population. North America was then repopulated by people with a different genetic ancestry.
@BallyBoy95 Denisovan DNA didn't skip the areas in between. They are present in all non-Africans to a certain degree, it's just that it's greatest in PNG.
There must have been some degree of isolation, because I remember reading about the two Denisovan groups (Altai vs South East Asia) being distinctly different genetically.

The genome that constructs the mechanisms of the mitochondria is split between the mitochondria and the nucleus. It is essential therefore that the male genome and the female mitochondrial genome are compatible. See Nick Lane’s The Vital Question
In my opinion the main advantage of modern over Neanderthal is metabolism...Neanderthals were high energy....in a large population the guy high energy types starve before lower metabolism types...famine does occur.
@@DennisMathias energy needs of people are a limiting factor in connection with their environment...the same environment will support more individuals with lower energy/metabolisms than high energy populations...if two populations come together one with genetically higher metabolisms and one with less energy requirements...when those joined populations experience famines those with higher energy needs starve first...the higher energy folks get weeded out...within the larger population
The view that the nongenetic DNA, the 98% that doesn't code for proteins, is unused is obsolete for over a decade, it is clear now that it is all regulatory since it is transcribed in regular ways in tissue. It also isn't as clocklike in its mutation as the speaker claims, there are locations which are conserved as well as any gene, and other locations that mutate rapidly. Further, it isn't mostly repetitive, much of it is "viral insertion", where I put "viral" in quotes because these are not likely to be disease causing viruses, but natural endoviral rewrites related to the mechanism of viruses.
I've been wondering about the very idea of obsolete or "left-over" genetic material. I think it's generally rash to assume that there's anything sitting around in our bodies that is superfluous to requirements. It seems to me to be a much better starting point to suppose that everything that's there has a function. Keeping a body going is expensive in energetic terms so I think we should assume that the superfluous stuff has pretty much all been eliminated.
@@danhanqvist4237 There are several places where DNA is "superfluous" in an information sense--- it's structural DNA for the ends of the chromosome, the telomere, or near the crossing point of the "X" structure. But those are understood. It's the part of the genome which is turned into RNA but not into protein that is functional, and that's well over 50%, more like 80%.
@@annaclarafenyo8185 Thanks. My point is that we should not assume that our ignorance really correspondence with how the world is. Just because we can't figure out what something does, doesn't mean it doesn't do anything.
1) DNA shows they are sister lineages. 2) Almost no substantial fossil remains have been found of Denisovans. Thus, no species description or holotype is possible, which makes morphological comparison between Neanderthals and Denisovans currently impossible.
@@andrew348 Right. They've literally only found about 4-5 small Denisovans bones. It was only from the DNA from one of those bones they discovered the Denisovans even existed.
Whatever is in action in our genetic code may be beyond human control at this time, yet, as our code develops to permit our understanding so that eventually we can help develop our own code to achieve better living and or the goals for which we were designed to achieve.

Agricultural reasearchers study wild populations of domesticated species like humans. Some times valuable genetic traits can be reintroduced into the domestic population.
Do we know something about the differences between the mitochondria that coexisted within the Neanderthal and the mitochondria that coexists today within the human?
There is one big problem with his terminology: all members of the genus homo are 'humans' thus Neanderthals are 'human'. So it really doesn't make sense to talk about human/neanderthal hybrids. Second, all non-African modern humans are essentially modern-human/neanderthal hybrids - or more precisely, descendants of such hybrids,
Most people think of 'human' as a species. Unfortunately species is not well defined. It would be reasonable, for example, to say nendrathal and homo sapiens are the same species. Also, knowledge has evolved. These terms came from a time [not to long ago] when we did not know that human/nendrathal hybrid was possible.
@@stevenpace892 Yes, it makes even less sense if Neanderthals were members of the homo sapiens species. But this video is only a year old so he knew enough to know better.
“…it wasn’t just Neanderthals and humans …”; “…and compare Neanderthal and human…”; “…Neanderthals were quite similar to humans…”; &c. Neanderthals were humans. We Sapiens are humans, too. There is no distinction in human terms between Neanderthals, erectus, sapiens, and habilis, &c. They are all human because they are all in the genus Homo-the human genus. “We might find late Neanderthals with human genes…” Indeed, every Neanderthal, as well as every erectus and denisovan and habilis and &c will have human genes because they are all human. Why not call our species “sapiens”? Yes, we are human, but we are not distinct humans from any other species in the genus Homo. So, in a human context such as this discussion we must use the specific word “sapiens” to distinguish ourselves from any other human species. One can say “modern humans” but does that obscurely mean us Homo sapiens or just the ones who exist in the modern era? But we cannot say “modern Neanderthals” because they no longer exist, but they were were also human. It is better to use the term “human” generically when discussing and comparing all human species. “Humans” are not distinct from Neanderthals: Neanderthals were as human as we are.
Species is not well defined. Nendrathals and humans did breed, and all nendrathal DNA is found in humans. They are similar, but not the same species. The did not commonly interbreed, a lot like dogs and wolves.
@@stevenpace892 -It is a bit more precise to define a species than a genus. Some consider Neanderthal and sapiens to be subspecies of the same species. The two discernible -uh-‘groups’ were certainly capable of reproducing fecund offspring, but our classification system(s?) statistically weight morphological distinctions, too, and Neanderthal was more markedly distinct from any sapiens than any sapiens differs from another of its own species today. Anthropology also considers behaviour and there’s a pretty good cased that, by all available evidence, sapiens and Neanderthal were quite different is this way as well. Finally, if Neanderthal and sapiens were so reproductively compatible as to class them as the same species, then why is Neanderthal DNA such distinctive (in modern sapiens) yet small component? If both were races of the same species, we should expect Neanderthal genes to be more evenly or broadly distributed in the sapiens genome as trait-distribution is among races of modern sapiens. But Neanderthal genes are not. Maybe there are or will be some other taxonomical system devised, but I think the current application (that the two are separate species) is as good as we have. For me the big question is whether it’s useful or not: the small amount of Neanderthal DNA in supra-Saharan modern sapiens has revealed -and probably will continue-many clues about diseases we sapiens suffer today that might help find a cure.
My dad is always talking about how scientists haven't found the missing link and yet at the same time he is the only other person I have ever heard tell that joke about faith lol
Here is something that could be a fun, exercise in probability. Have AI’s generate human images from genetic interpretation. In other words teach an AI what the particular gene does and let in put together a composite of what it thinks a human should look like from the Gene sequence it’s given. I wonder if the AI would have us looking like giant blobs. 😂
Before we can teach AI to do that we would have to fully understand it ourselves. We know a couple of genes and how they influence, for example, skin and hair and eye colour, but there are a lot where we don't know how they influence the phaenotype (looks).
I don't beleive AI thinks at all. It just takes what information has been fed into it and produces it. It does seem able to interpret what is logical but I think that is on the basis of comparing statements. I don't think it is creative at all, and actually forming hypothesis and imagining possibities is what humans can do and not AI.
@johnchristopherrobert1839 There's now reason why you would need an AI to do this, but the concept of a computer program that can predict the phenotype based on the genotype is something every geneticist dreams of. Unfortunately, we are so far away from doing it that it's not worth spending a whole lot of time thinking about.
This is a work in progress. Obviously the police would like to know as much as possible about a person from their DNA; interesting facts would include their face, first and last name, etc. clues to these facts are in the DNA. And these technologies are being developed.
The speaker gets into a bit of a knot when he speaks about the "hybrids". The existence of fertile "hybrids" rather shows that Neandertals and "humans" were the same species, but just rather different populations.
I just can not believe than humans from Arica became Russian and Chinese !! Mu theory is that each part of the world had its (own) humans so like any other animal and plants
Like it or not, there are no genes unique to a race. The probabilities are very different but the collection of genes is the same. Human is ONE species.
Speaking of cars, boats, and helicopters and what makes us different? A little comparative anatomy will show that Neanderthal is an ambush predator while we are persuit predators. Very different animals. For instance, we can perform an overhead throw which Neanderthal couldn't, and we can do it while running. Neanderthal lacked an achiles tendon, for another instance, which means they weren't runners. Their musculature was arranged for a sturdy vertical structure.They stood in a bent kneed pronated stance, perfect for thrusting up with a lance. They lived in dense forest, in groups numbering no more than 50 with miles and miles between groups. We live in coastal or riparian environments, in small communities with upwards of 150 people and another community within a half day walk. We kill at distance, while they killed within reach or grasp. And there would be a myriad of cultural differences resulting from just these. Neanderthals are nothing like us.
This was an excellent lecture, but I do have a few suggestions for you to look into, in order to make it even better. Not to be presumptuous or insulting, but it seems your specialty is genetics, not primates. A couple of things about chimps (and about orangs and bonobos), courtesy of Erika, better known as Gutsick Gibbon on here. She is a primatologist, nearing her PhD, and has several very helpful videos. Chimps are in their stone age, and are known to make different tools differently in different areas. They are also warlike, very much like us. They recently were seen to go to war against a group of _gorillas,_ not just other tribes of chimps. Also, bonobos are actually in many ways are more closely related to us than chimpanzees, one of which is most relevant to your lecture. There have been multiple studies showing our genetics are more similar to bonobos than chimpanzees. They also have certain activities that we have which chimps don't have which have been seen by scientists studying them. There's a lab in a forest in the Democratic Republic of the Congo, called Lola ya Bonobo. Research there has produced more than 75 published studies over the last few years, showing, among other things, that bonobos show kindness - even to strangers - more than any other primate besides maybe us. I'd suggest you look into the results: they are brilliant, IMO, and to me, very telling. Two negatives: You pronounced orangutan incorrectly. There is NO G at the end of orangutan. They are NOT orangutanGs. You actually pronounce the word like most creationists do, in fact. It was very disturbing. And one final thing: we are not "entities" when we are a haploid sperm or egg, nor are we "entities" in our own right until we are capable of functioning outside of the uterus on our own, around the 20th week or so. You are sticking some non-science something, perhaps humanism, deism, or theism, into the science you are talking about. It really doesn't belong there.
This lecture is very old, even though it was uploaded to UA-cam recently. Some of that information you cite may be more recent than the lecture. I wish they had made it much more obvious how old this material is.
you never are independent entity you have no truly free will, you aren't conscious most of time, you carry views of which nearly none were your personal creation you aren't independent sane entity especially in phase of hormonal overreaction state of modern science only proves it all these arguments of being factual is usually covering personal biases
It is exactly 50%. Each parent provides one of the two copies [all of us had 2]. Our parents in turn, have 1/2 from each parent. That means if you are lucky enough to have 4 grandparents, it is 25% each. What 25% is random though.
Heres a new idea, what if the earliest hominids (4, 5, maybe 10 million years ago) were all bipedal all along from Day 1? But we were so violent and deadly due to our bipedalness allowing for handheld weapons to be swung with greater force, we drove all the other primate groups of great apes' ancestry up into the trees for protection where they developed hands and feet for climbing. It's difficult to climb a tree and carry a rock at the same time and we're still working on improving the solutions to that problem to this day. Hominins didnt come down from the trees, we drove the hominids up into the trees.

Chimpanzee behavior is not similar to that of humans on the Autism spectrum. Normal chimps look you right in the eyes and have complicated, nuanced social interactions with other chimps. The book 'Chimpanzee Politics' by Frans de Waal does a good job of conveying the sophistication of chimp social abilities.
Gol, tighten it up. QUOTE "Go backwards in life, when you were child, when you were toddler, when you were baby, when you were (pause) an egg cell..." so many meaningless words. Epitome of blah blah blah, Where s the beef.
I disagree with what he said about autism, us, dogs, and most of the rest of animals. Lots of other critters live in social groups and look each in the eye. They are happier to be with their own than by themselves. I figure the rise in autism in North America is probably because of all the man made crap in our food and water. Including “organic” that is grown where there used to be pesticides, herbicides, and chemical fertilizers used. Still in the soil. May be in acceptable levels in one thing but they do not seem to consider that the stuff is in lots of things. Then there is genetic modifications created in labs. I gather that those who drink water bottled in plastic are more likely to get arthritis or get it sooner. I inagine how long the water is in the plastic bottles before someone drinks it makes a difference. There may be no getting around it because of the plastic particles in the stuff we eat as well. Where else is autism on the rise?
They also have the same elements, carbon, nitrogen, hydrogen etc. The expression and when and where is as important as sequence. A single mutation can lead to severe mental retardation, problem with bipedalism, etc. Besides epigenetic and chromatin disposition. Toosimplistic to just look at linear genome sequence. Without genome sequence from H. Erectus it is difficult to say what were the differences. Hominid is not human. Awkward fact seems to be that proximity of genome, the engine of evolution , is not sufficient to explain the human phenotype. No evidence chimps are evolving, they appear to be quite stable in their niche for the last 3.5 million years.
I think that apes evolved from humans or some form of human. Arboreal evolution followed a lengthening of arms and shortening of legs resulting in the ape from million of year’s ago. Humans evolved from an aquatic monkey much earlier in time.
A different number of chromosomes means you can not breed, but given everything else is the same, the two animals are VERY similar. It is like a version of a program running on the MAC, the other on PC. Not compatible but they do the same thing.
There is no reason to think that Neanderthals would not have been as inventive as HS, given time and enough population numbers to generate the flow of ideas that leads to urbanisation and so on…
Does the genetic contribution from neanderthals to the non-african group explain why there such a great difference between the African group and the other groups, especially as it relates to intelligence?
@@eddiemunster8634 I apologize for my clumsy phrasing. When I read your question, it made me think of the fact that for decades, people have claimed that African Americans are less intelligent than white Americans based on IQ scores. However those IQ tests have questions that make assumptions about cultural knowledge, such as specific vocabulary or life experiences. Therefore, differences in scores on such tests sometimes point to differences in cultural knowledge, rather than differences in intelligence. Please point me to evidence that there is an intelligence difference between Africans and non-Africans.
South east Asians aren't much smarter than Africans so it's more related to climate and selection people on north have less children these children don't die so often or randomly and they put more resources in their growth in Africa it's all about higher numbers and sheer luck

As I watch dozens of these talks, I'm struck by the obsession of speakers, scholars, with how different we humans are from all other species. That perception is false.
42:00 Are you now talking about the main DNA? The flow of the talk suggests you're still talking about mitochondrial DNA, but that only flows from mother to daughter, in a pure uncrossed tree, so how could it be closer to European humans than African humans? Also you go on to belabor the point that Native American DNA shares this differential trait but that's no surprise as Native Americans are known with absolute certainty to simply be wayward Asians.
There are many neanderthal traits that can be observed in people today. My son has the occipital bun and I don't. The occipital bun is fairly common. Although I do have a pronounced eyebrow ridge. There is a picture of the two sculls available in google images. The neanderthal nose comes away from the scull at a much sharper angle. This gives people a big nose or sometimes a hook nose or a lump where the bone ends, like the nose of the speaker. Autism is possibly caused by neurotoxins in immunizations. There are many cases online where people have video of their children before and after immunization. The transformation for the worst is obvious.
The studies linking autism and vaccination have been proven falsified, over and over again. What is far more likely is that the genes causing various forms of autism turn on and express at ages that coincide with ages for primary vaccination. One has nothing to do with the other.
Unfortunately, many childhood immunizations are given right around the same age that the symptoms of autism are likely to show up. Correlation is heartbreaking, but not evidence of causation. What neurotoxins do you think there are in immunizations? No modern childhood vaccines have mercury in more than vanishingly trace amounts (left over thimerosal that was mostly removed at the end of the manufacturing process; the body breaks down thimerosal into ethylmercury, which is different from the neurotoxin methylmercury), and no reputable scientific study (Wakefield's study had many many problems) has found any association between vaccines and autism.
@@JaniceinOR Right, however in contrast to any correlation with immunisations, the correlation with ritual infant penectomy has a very plausable explanation in the trauma of the ritual triggering the genetic disposition. Unfortunately little interest has been shown in exploring this further in the eight years since the correlation was shown to exist thanks to Western, mostly US, cultural bias and despite the increasing interest in autism.
@@fritnat Are you claiming a link between circumcision and autism? Where was this correlation shown? Is there any data looking at the relative ratios? The groups to compare would be: A1) people who were circumcised and have autism; A2) people who were not circumcised and have autism; B1) people who were circumcised and do not have autism; B2) people who were not circumcised and do not have autism. To support your claim, A1/B1 would have to be significantly larger than A2/B2. Further work would also need to show that there were not confounding factors.

One of the best lectures in paleontology. Dr. Green's presentation was exceptional. He explained difficult concepts with clarity and precision. He is a talented teacher !!!
I thought 'this will be too technical': watched it all though!
Having formal education in plant and animal science, including courses in genetics and having spent my life in grain and animal production, I marvel at the superiority of the F1 cross. My hats off to the first Neanderthal Homo sapien couple!
The Basques of Northern Spain are LIVING WALKING TALKING NEANDERTHALS. As PROVEN by British Medical Science over 10 years ago. These people exhibit as high as 75% Neanderthal DNA. Have RESUS NEGATIVE Blood, the KNOWN Neanderthal blood type, which does NOT work in humans properly & causes medical issues. Indeed the Basque language with NO connection to ANY Human language is itself the Neaderthal language. So Professor Green, giving the talk, must have spent the last 10 years living on a lost Pacific island, as virtually everyone else in the Scientific community is aware of that Bombshell 10-12 years ago !!!!!

I find your subject matter fascinating. I didn’t study any of this in University, but just stumbled on it while scrolling through You Tube about six months ago. Now i cant get enough of it. I look for new videos every night. I am particularly fascinated by Neanderthals.
While visiting France as a child there was a shopkeeper in Strasbourg with the most pronounced brow ridge I have ever seen on a human. He also had a head of enviable coarse hair and fingers twice as thick as my dad's. I knew then and there where the Neanderthals had gone, nowhere they were still here.
Still here and living in France.
Did he have acromegaly instead?

What are you talking about???!!
Not enough facts ! As British Medical Science proved and announced that the Basques of Northern Spain are LIVING WALKING TALKING NEANDERTHALS, OVER 10 YEARS AGO !!! Indeed the Basques have as much as 75% Neanderthal DNA and of course have RESUS NEGATIVE Blood the known Neanderthal Blood group which does NOT work in Humans properly & causes medical issues particularly in women. And we now even know that the weird Basque Language which has NO connection to any Human Language has to be the remnants of the Neanderthal Language.
All of the above was published in numerous Medical Science journals over 10 years ago !!!!
So the Professor giving this talk, has either been living on a deserted island for over 10 years, or he's stone deaf, or just plain IGNORANT !!!

My dude, not only minds are dynamical systems ( as Lenny da Vinci noted of the heart, "never stopping unless forever") but also your very brains are, with neurons CONSTANTLY budding new dendrites, with astrocytes and other monitors of USE nipping off the unused of that efficient energy consumer (as thus, YES, we are all brilliant teenagers consuming refrigerator contents in quantities distressing to economizing mammas).
(and one of the astonishing artists who helped me, also observed this: " anything you do contains the universe", meaning all that you have known, do, and can, know.

The problem with missing links is that every time they become found links they shrink.
In the 2011 CARTA video, Ed made it clear that the "12.7" percent was measuring chimp-like DNA in Neanderthal. It would be interesting if any archaic humans (e.g. Ust-Ishim) had any such chimp-like DNA, which would verify the molecular clock theory.
Loved this! Thank you…
Just a quick note, vit D is very low naturally in milk, that is why milk is fortified with Vit D
Yes, he mixed that up with the light skin gene which had to do with vitamin D in northern latitudes.
According to Johannes Krause (whom the lecturer probably knows or has met during his time in Leipzig), the lactase thing only became prevalent during the middle ages when cows were bred to give more milk.
@@johannageisel5390 famous story from Homer's Odyssey describes Odysseus' encounter with the cyclops Polyphemus who is milking goats and making cheese. The story, to my understanding, predates the middle ages by about 2000 years and suggests adult humans were making lactase.
@@IbnFarteen In cheese and other processed milk products (yoghurt etc.) the lactose content is usually lower, because bacteria turn the lactose into other substances.
That's why people with mild lactose intolerance have no trouble eating cheese and yoghurt, but might get problems when drinking milk.
But yes, the ability to make lactase as an adult at least in small amounts is probably older. But it spread to most of the adult European populace only relatively recently. It was rarer before.
@@johannageisel5390So you're saying that a mutation in the middle ages spread to most of Northern Europe?
@@wooddoc5956 It was a couple of years ago, so I'm not certain anymore. I may misremember it or misunderstood him.
Maybe he was talking about something like the latest uptick in lactose tolerance in Europe.
Or he actually said "Middle Bronze Age" and I just misheard it completely.
I looked around the internet and couldn't find anything that said "Middle Ages", so I admit I probably got that wrong.
And it seems that generally the development of lactase persistency took a while to spread.
"By mapping patterns of milk use over the last 9,000 years, probing the UK Biobank, and combining ancient DNA, radiocarbon, and archaeological data using new computer modelling techniques, the team were able to show that the lactase persistence genetic trait was not common until around 1,000 BC, nearly 4,000 years after it was first detected around 4,700-4,600 BC."

A pack of outdated Garbage ! As over 10 years ago numerous Medical Science Journals reported the amazing tests carried out on the Basques in Northern Spain, by BRITISH MEDICAL SCIENCE. Which revealled the Basques are LIVING WALKING TALKING NEANDERTHALS, with up to 75% Neanderthal DNA. "Resus Negative" NEANDERTHAL BLOOD, and even their weird Language has to be the remnants of the Neandertal Language.

52:20 Our phase of being haploids is indeed long: from near our mother's conception (she is born with our egg) until fertilization. Many, many people have been haploids longer than they've been diploids, given the fact that a huge number of humans (especially in the fastest-growing countries) are younger than their mom was at conception.

Thank you, a great explanation and one even I could follow.
I also enjoyed this detailed discussion of anthropological history - and the underlying suggestion of the alternative ways in which the anthropological rhetoric may be used to excuse or conceal modern conservative attitudes. I would only add, Mr Lerie2010able, that you ought not to depreciate the worth of your judgment about human worth. There is nothing to be gained by using expressions such as “even I could understand”.
Starting at around 52:00, the discussion of gene shuffling from grandparents to current generation, seems different from what I've seen in usual layman - i.e., me - discussions.
Are there good sources online that explain this in greater detail? Thanks.
I've seen stuff on sites like Ancestry's genetic portion of their site, and I also believe 23 & Me, as well. I recall one article that explained why one sister of (3 or 4) didn't inherit any of one portion of the family's ancestry (Irish, if memory serves) that the other sisters had varying percentages, up to something like 75%, showing in their results.
Perhaps you could investigate there for some answers to your questions. 🙂

@jimvj5897 David Reich (whom he mentions early in the video) describes it similarly, but it's not really that accurate to describe it that way in my opinion because we obviously get our genes from our parents. What he means is that we get very long segments that are unchanged from our grandparents (via our parents). These segments can be millions of base-pairs long. The important thing is that if you look at two people's DNA and they have very long segments that are identical (in areas of the DNA that are not normally identical) you can conclude that they had a common ancestor within a few generations. The shorter those segments are, the further back the common ancestor is.

47:10 - How the Denisova DNA got all the way from Siberia to Papua New Guinea, whilst skipping India/Indonesia is fascinating.
Unless those areas were invaded/settled by new migrant populations ofc, which would make sense.
Bear in mind the Siberian sample is ancient, and the PNGuinea samples are where they find the highest traces in modern humans today. So Denisovans could have been all across Asia + India in antiquity, then some sort of regional disaster - perhaps a volcano, asteroid impact, plague or disease - completely wiped the population out with the exception of the the southern islands. Then humans moved in and repopulated the area, interbreeding with the small remaining Denisovans population that still existed only in those southern islands before that branch went extinct. This sort of thing has happened in history numerous times. @12,000 years ago, something happened that vanished the Clovis culture people from all of the North America. Their DNA only shows up in Central and South American populations today. They used to be across all the Americas but the decimation was regional to the northern population. North America was then repopulated by people with a different genetic ancestry.
Denisovans perfected the skipping technique. You're welcome!
Dislocation by other migrants
@BallyBoy95 Denisovan DNA didn't skip the areas in between. They are present in all non-Africans to a certain degree, it's just that it's greatest in PNG.
There must have been some degree of isolation, because I remember reading about the two Denisovan groups (Altai vs South East Asia) being distinctly different genetically.

In my opinion the main advantage of modern over Neanderthal is metabolism...Neanderthals were high energy....in a large population the guy high energy types starve before lower metabolism types...famine does occur.
Depends on the climate. When the ice age was upon us, Hn did great because they were adapted for it.. Around longer than we have been.
@@DennisMathias energy needs of people are a limiting factor in connection with their environment...the same environment will support more individuals with lower energy/metabolisms than high energy populations...if two populations come together one with genetically higher metabolisms and one with less energy requirements...when those joined populations experience famines those with higher energy needs starve first...the higher energy folks get weeded out...within the larger population

No. Jot nessecarily. But definitely high protein and fat fuel demand.
The view that the nongenetic DNA, the 98% that doesn't code for proteins, is unused is obsolete for over a decade, it is clear now that it is all regulatory since it is transcribed in regular ways in tissue. It also isn't as clocklike in its mutation as the speaker claims, there are locations which are conserved as well as any gene, and other locations that mutate rapidly. Further, it isn't mostly repetitive, much of it is "viral insertion", where I put "viral" in quotes because these are not likely to be disease causing viruses, but natural endoviral rewrites related to the mechanism of viruses.
I've been wondering about the very idea of obsolete or "left-over" genetic material. I think it's generally rash to assume that there's anything sitting around in our bodies that is superfluous to requirements. It seems to me to be a much better starting point to suppose that everything that's there has a function. Keeping a body going is expensive in energetic terms so I think we should assume that the superfluous stuff has pretty much all been eliminated.
This guy is off base on some other stuff too…Egregiously so.
@@nomandad2000 No, he's mostly on point, just a little out of date regarding biology. It's overall a great lecture.

Some say the Neanderthals were a small, more robust subgroup of the Denisovans.
1) DNA shows they are sister lineages. 2) Almost no substantial fossil remains have been found of Denisovans. Thus, no species description or holotype is possible, which makes morphological comparison between Neanderthals and Denisovans currently impossible.

Excellent!
There is one big problem with his terminology: all members of the genus homo are 'humans' thus Neanderthals are 'human'. So it really doesn't make sense to talk about human/neanderthal hybrids. Second, all non-African modern humans are essentially modern-human/neanderthal hybrids - or more precisely, descendants of such hybrids,
Most people think of 'human' as a species. Unfortunately species is not well defined. It would be reasonable, for example, to say nendrathal and homo sapiens are the same species. Also, knowledge has evolved. These terms came from a time [not to long ago] when we did not know that human/nendrathal hybrid was possible.
@@stevenpace892 Yes, it makes even less sense if Neanderthals were members of the homo sapiens species. But this video is only a year old so he knew enough to know better.
@@gastronomist no, we didn't think they were human; they were 'clearly' distinct from homosapien. Appearances can be deceiving; that was my point.
@@stevenpace892 That's incorrect. The idea that Neanderthals are a subspecies of homo sapiens has been around for a long time and is still debated.
I have a missing link living next door to me. Plumber man.
Read the title as "Netherlands Gnomes Project"
“…it wasn’t just Neanderthals and humans …”; “…and compare Neanderthal and human…”; “…Neanderthals were quite similar to humans…”; &c.
Neanderthals were humans. We Sapiens are humans, too. There is no distinction in human terms between Neanderthals, erectus, sapiens, and habilis, &c. They are all human because they are all in the genus Homo-the human genus.
“We might find late Neanderthals with human genes…” Indeed, every Neanderthal, as well as every erectus and denisovan and habilis and &c will have human genes because they are all human. Why not call our species “sapiens”? Yes, we are human, but we are not distinct humans from any other species in the genus Homo. So, in a human context such as this discussion we must use the specific word “sapiens” to distinguish ourselves from any other human species.
One can say “modern humans” but does that obscurely mean us Homo sapiens or just the ones who exist in the modern era? But we cannot say “modern Neanderthals” because they no longer exist, but they were were also human.
It is better to use the term “human” generically when discussing and comparing all human species. “Humans” are not distinct from Neanderthals: Neanderthals were as human as we are.
Species is not well defined. Nendrathals and humans did breed, and all nendrathal DNA is found in humans. They are similar, but not the same species. The did not commonly interbreed, a lot like dogs and wolves.
@@stevenpace892 -It is a bit more precise to define a species than a genus. Some consider Neanderthal and sapiens to be subspecies of the same species. The two discernible -uh-‘groups’ were certainly capable of reproducing fecund offspring, but our classification system(s?) statistically weight morphological distinctions, too, and Neanderthal was more markedly distinct from any sapiens than any sapiens differs from another of its own species today.
Anthropology also considers behaviour and there’s a pretty good cased that, by all available evidence, sapiens and Neanderthal were quite different is this way as well.
Finally, if Neanderthal and sapiens were so reproductively compatible as to class them as the same species, then why is Neanderthal DNA such distinctive (in modern sapiens) yet small component? If both were races of the same species, we should expect Neanderthal genes to be more evenly or broadly distributed in the sapiens genome as trait-distribution is among races of modern sapiens. But Neanderthal genes are not.
Maybe there are or will be some other taxonomical system devised, but I think the current application (that the two are separate species) is as good as we have. For me the big question is whether it’s useful or not: the small amount of Neanderthal DNA in supra-Saharan modern sapiens has revealed -and probably will continue-many clues about diseases we sapiens suffer today that might help find a cure.
My dad is always talking about how scientists haven't found the missing link and yet at the same time he is the only other person I have ever heard tell that joke about faith lol
This guy should invent a anti aging line and patent it . He would be the poster boy of phenomenal skin .
Here is something that could be a fun, exercise in probability. Have AI’s generate human images from genetic interpretation. In other words teach an AI what the particular gene does and let in put together a composite of what it thinks a human should look like from the Gene sequence it’s given. I wonder if the AI would have us looking like giant blobs. 😂
Before we can teach AI to do that we would have to fully understand it ourselves. We know a couple of genes and how they influence, for example, skin and hair and eye colour, but there are a lot where we don't know how they influence the phaenotype (looks).
I don't beleive AI thinks at all. It just takes what information has been fed into it and produces it. It does seem able to interpret what is logical but I think that is on the basis of comparing statements. I don't think it is creative at all, and actually forming hypothesis and imagining possibities is what humans can do and not AI.
DNA doesn't have information how to make you
only how to make organic materials
it knows nothing how to build an organ
@johnchristopherrobert1839 There's now reason why you would need an AI to do this, but the concept of a computer program that can predict the phenotype based on the genotype is something every geneticist dreams of. Unfortunately, we are so far away from doing it that it's not worth spending a whole lot of time thinking about.
This is a work in progress. Obviously the police would like to know as much as possible about a person from their DNA; interesting facts would include their face, first and last name, etc. clues to these facts are in the DNA. And these technologies are being developed.
Oh dear. That first answer was legitimately painful to hear
130,000 years for earliest homosapien fossil record? I thought it went back at least 300,000?
The speaker gets into a bit of a knot when he speaks about the "hybrids". The existence of fertile "hybrids" rather shows that Neandertals and "humans" were the same species, but just rather different populations.
I just can not believe than humans from Arica became Russian and Chinese !! Mu theory is that each part of the world had its (own) humans so like any other animal and plants
Like it or not, there are no genes unique to a race. The probabilities are very different but the collection of genes is the same. Human is ONE species.

Speaking of cars, boats, and helicopters and what makes us different? A little comparative anatomy will show that Neanderthal is an ambush predator while we are persuit predators. Very different animals. For instance, we can perform an overhead throw which Neanderthal couldn't, and we can do it while running. Neanderthal lacked an achiles tendon, for another instance, which means they weren't runners. Their musculature was arranged for a sturdy vertical structure.They stood in a bent kneed pronated stance, perfect for thrusting up with a lance. They lived in dense forest, in groups numbering no more than 50 with miles and miles between groups. We live in coastal or riparian environments, in small communities with upwards of 150 people and another community within a half day walk. We kill at distance, while they killed within reach or grasp. And there would be a myriad of cultural differences resulting from just these. Neanderthals are nothing like us.

This was an excellent lecture, but I do have a few suggestions for you to look into, in order to make it even better.
Not to be presumptuous or insulting, but it seems your specialty is genetics, not primates. A couple of things about chimps (and about orangs and bonobos), courtesy of Erika, better known as Gutsick Gibbon on here. She is a primatologist, nearing her PhD, and has several very helpful videos.
Chimps are in their stone age, and are known to make different tools differently in different areas. They are also warlike, very much like us. They recently were seen to go to war against a group of _gorillas,_ not just other tribes of chimps.
Also, bonobos are actually in many ways are more closely related to us than chimpanzees, one of which is most relevant to your lecture. There have been multiple studies showing our genetics are more similar to bonobos than chimpanzees. They also have certain activities that we have which chimps don't have which have been seen by scientists studying them.
There's a lab in a forest in the Democratic Republic of the Congo, called Lola ya Bonobo. Research there has produced more than 75 published studies over the last few years, showing, among other things, that bonobos show kindness - even to strangers - more than any other primate besides maybe us. I'd suggest you look into the results: they are brilliant, IMO, and to me, very telling.
Two negatives:
You pronounced orangutan incorrectly. There is NO G at the end of orangutan. They are NOT orangutanGs. You actually pronounce the word like most creationists do, in fact. It was very disturbing.
And one final thing: we are not "entities" when we are a haploid sperm or egg, nor are we "entities" in our own right until we are capable of functioning outside of the uterus on our own, around the 20th week or so. You are sticking some non-science something, perhaps humanism, deism, or theism, into the science you are talking about. It really doesn't belong there.
Why are you offended over a decade old lecture?
This lecture is very old, even though it was uploaded to UA-cam recently. Some of that information you cite may be more recent than the lecture.
I wish they had made it much more obvious how old this material is.
you never are independent entity
you have no truly free will,
you aren't conscious most of time,
you carry views of which nearly none were your personal creation
you aren't independent sane entity especially in phase of hormonal overreaction

My brother and I have pronounced occipital buns. To a degree that makes motorcycle helmets not fit.
22:05 I thought the laws of independent assortment made it so you’re not exactly 50% your parents and 25 % your grandparents
It is exactly 50%. Each parent provides one of the two copies [all of us had 2]. Our parents in turn, have 1/2 from each parent. That means if you are lucky enough to have 4 grandparents, it is 25% each. What 25% is random though.
Amazing! Thank you!
but there is a 1-st generation Neanderthal-Denisovan hybrid
Thank you so much.
He said humans came out of Africa and interbred with Neandrathal but didn't explain where Neandrathal came from!
Africa.
We were not bored, (just a little confused). Yet, i hope the lecturer (/ conferent) was not bored to have to explain at the level of our ignorance 😄
☘️ imagine that ☘️
This is the most inexact science ive ever seen.
What’s the title of your thesis in biology?
Thanks Professor, when can I attend your lectures in Applied Ignorance?
Heres a new idea, what if the earliest hominids (4, 5, maybe 10 million years ago) were all bipedal all along from Day 1? But we were so violent and deadly due to our bipedalness allowing for handheld weapons to be swung with greater force, we drove all the other primate groups of great apes' ancestry up into the trees for protection where they developed hands and feet for climbing. It's difficult to climb a tree and carry a rock at the same time and we're still working on improving the solutions to that problem to this day. Hominins didnt come down from the trees, we drove the hominids up into the trees.
Yes - You may enjoy a very short article by Brewster Smith, (Circa 1970), included in a collection of essays entitled, “What it Means to Be Human”, Ed. by Steven Fitzgerald.
@@victorsauvage1890 thank you
Sounds like a good video game but there's no reason to think that.
KenSoHappyClegg You have put forward an interesting thesis - I am unable to see any important error in your idea - “wooddoc5956”, suggests that your idea is superfluous - I would be interested to hear him describe exactly how your idea could be simplified.
@@victorsauvage1890 The fossil record Goes from tree dwelling to bipedalism. The evolution of climbing hands to holding hands Is well known. Why would you think reversing that process is justified?
good job Denis.
Human differences from apes...? Bipedalism and Ballet. Opposable Thumbs; From Moroccan beads to Man on the Moon. Self-Consciousness and Shakespeare; ''What a piece of work is a man, How noble in reason, how infinite in faculty, In form and moving how express and admirable, In action how like an Angel, In apprehension how like a god, The beauty of the world, The paragon of animals.''
IMO "man on the moon" is proof of our superior (unique?) skill for deceit that is a worse virus than the Ukraine UNC bio labs are developing.
The older i get, the more i appreciate Shakespeare's imagination. Either that or people were more impressive in his time.
Chimpanzee behavior is not similar to that of humans on the Autism spectrum.
Normal chimps look you right in the eyes and have complicated, nuanced social interactions with other chimps.
The book 'Chimpanzee Politics' by Frans de Waal does a good job of conveying the sophistication of chimp social abilities.
I don't know about chimps specifically, but in most apes, eye contact is a challenge.,
Gol, tighten it up. QUOTE "Go backwards in life, when you were child, when you were toddler, when you were baby, when you were (pause) an egg cell..." so many meaningless words. Epitome of blah blah blah, Where s the beef.
Why did we evolve but not the apes?? should they exist??
Apes have evolved as much as we gave. Just in other directions. We are not more evolved.
Same reason as we don't see just one species of birds or bears or elephant.... Different species develop and not all lines die off.
I disagree with what he said about autism, us, dogs, and most of the rest of animals. Lots of other critters live in social groups and look each in the eye. They are happier to be with their own than by themselves.
I figure the rise in autism in North America is probably because of all the man made crap in our food and water. Including “organic” that is grown where there used to be pesticides, herbicides, and chemical fertilizers used. Still in the soil. May be in acceptable levels in one thing but they do not seem to consider that the stuff is in lots of things. Then there is genetic modifications created in labs.
I gather that those who drink water bottled in plastic are more likely to get arthritis or get it sooner. I inagine how long the water is in the plastic bottles before someone drinks it makes a difference. There may be no getting around it because of the plastic particles in the stuff we eat as well.
Where else is autism on the rise?
They also have the same elements, carbon, nitrogen, hydrogen etc. The expression and when and where is as important as sequence. A single mutation can lead to severe mental retardation, problem with bipedalism, etc. Besides epigenetic and chromatin disposition. Toosimplistic to just look at linear genome sequence.
Without genome sequence from H. Erectus it is difficult to say what were the differences.
Hominid is not human.
Awkward fact seems to be that proximity of genome, the engine of evolution , is not sufficient to explain the human phenotype. No evidence chimps are evolving, they appear to be quite stable in their niche for the last 3.5 million years.
Extinction is unfortunate and our lasting legacy.
I think what God said was, "I'm not a god. You should have saved yourself".
Wonderful thank you very much
I think that apes evolved from humans or some form of human. Arboreal evolution followed a lengthening of arms and shortening of legs resulting in the ape from million of year’s ago. Humans evolved from an aquatic monkey much earlier in time.
How are we so closeĺy related to chimps when we have a different amount of chromosomes?
our chromosome 2 is a fusion of primate chromosomes 12 and 13. This was conjectured before it could be tested. it's been know now for some time.
A different number of chromosomes means you can not breed, but given everything else is the same, the two animals are VERY similar. It is like a version of a program running on the MAC, the other on PC. Not compatible but they do the same thing.
@@mcmanustony Any idea how long ago that fusion occured?

There is no reason to think that Neanderthals would not have been as inventive as HS, given time and enough population numbers to generate the flow of ideas that leads to urbanisation and so on…
Excellent
Does the genetic contribution from neanderthals to the non-african group explain why there such a great difference between the African group and the other groups, especially as it relates to intelligence?
What intelligence difference between Africans and non-Africans that is not related to culturally dependent questions?
@@JaniceinOR all of it, intelligence is innate and not culturally related
@@eddiemunster8634 I apologize for my clumsy phrasing.
When I read your question, it made me think of the fact that for decades, people have claimed that African Americans are less intelligent than white Americans based on IQ scores. However those IQ tests have questions that make assumptions about cultural knowledge, such as specific vocabulary or life experiences. Therefore, differences in scores on such tests sometimes point to differences in cultural knowledge, rather than differences in intelligence.
Please point me to evidence that there is an intelligence difference between Africans and non-Africans.
South east Asians aren't much smarter than Africans
so it's more related to climate and selection
people on north have less children these children don't die so often or randomly
and they put more resources in their growth
in Africa it's all about higher numbers and sheer luck
@@eddiemunster8634 your intelligence and conditions letting you use it properly are two completely different things
you can have best potential and still die last outcompeted because conditions do not care about your smartness
As I watch dozens of these talks, I'm struck by the obsession of speakers, scholars, with how different we humans are from all other species.
That perception is false.
I love Prof. Green so much! And maybe love his wife even more, Prof. Shapiro!!
So classifications of different homos is not an exact science but is a lot of conjecture?
I thank you for your lecture.
I hope you find better educated people to lecture to.
Try outside the USA.
42:00 Are you now talking about the main DNA? The flow of the talk suggests you're still talking about mitochondrial DNA, but that only flows from mother to daughter, in a pure uncrossed tree, so how could it be closer to European humans than African humans? Also you go on to belabor the point that Native American DNA shares this differential trait but that's no surprise as Native Americans are known with absolute certainty to simply be wayward Asians.
There are many neanderthal traits that can be observed in people today. My son has the occipital bun and I don't. The occipital bun is fairly common. Although I do have a pronounced eyebrow ridge. There is a picture of the two sculls available in google images. The neanderthal nose comes away from the scull at a much sharper angle. This gives people a big nose or sometimes a hook nose or a lump where the bone ends, like the nose of the speaker. Autism is possibly caused by neurotoxins in immunizations. There are many cases online where people have video of their children before and after immunization. The transformation for the worst is obvious.
The studies linking autism and vaccination have been proven falsified, over and over again. What is far more likely is that the genes causing various forms of autism turn on and express at ages that coincide with ages for primary vaccination. One has nothing to do with the other.
Unfortunately, many childhood immunizations are given right around the same age that the symptoms of autism are likely to show up. Correlation is heartbreaking, but not evidence of causation.
What neurotoxins do you think there are in immunizations?
No modern childhood vaccines have mercury in more than vanishingly trace amounts (left over thimerosal that was mostly removed at the end of the manufacturing process; the body breaks down thimerosal into ethylmercury, which is different from the neurotoxin methylmercury), and no reputable scientific study (Wakefield's study had many many problems) has found any association between vaccines and autism.
@@JaniceinOR Right, however in contrast to any correlation with immunisations, the correlation with ritual infant penectomy has a very plausable explanation in the trauma of the ritual triggering the genetic disposition. Unfortunately little interest has been shown in exploring this further in the eight years since the correlation was shown to exist thanks to Western, mostly US, cultural bias and despite the increasing interest in autism.
@@fritnat
Are you claiming a link between circumcision and autism? Where was this correlation shown?
Is there any data looking at the relative ratios? The groups to compare would be:
A1) people who were circumcised and have autism;
A2) people who were not circumcised and have autism;
B1) people who were circumcised and do not have autism;
B2) people who were not circumcised and do not have autism.
To support your claim, A1/B1 would have to be significantly larger than A2/B2.
Further work would also need to show that there were not confounding factors.
@@JaniceinOR "Ritual circumcision and risk of autism spectrum disorder in 0- to 9-year-old boys: national cohort study in Denmark" Frisch et al 2015. Do you have a special interest in autism?

I think the case could be made that the African group is a separate species from the non-african group.
This talk seems very dated. 7 billion was the population in 2011.
The lecture was in 2012.
Yes, but published here only a year ago. Instead of "This draft sequence yields important new insights," I would have put out a disclaimer to the effect that some of the information presented has been superceded.
@@Paulus8765 You're right. Especially for sapien's DNA in Néandertal. If I'm not wrong we gave him our Y and mt chromosomes.
