Just about to apply to a master's programme in Population Genetics, focusing on endangered species. This video really inspired me to find the inner spark again, writing the best possible application letter I could write! Quite often, those sparks are kept hidden away, since it is not always accepted being a "nerd". Thank you for sharing your joy about your subject! And for the record - I know many of us nerds would be thrilled to talk biology with you at any party!
@@pumaconcolor2855 Oh wow. What a fun thing to come back to 6 years later! Thank you for asking - and for reminding me of this memory. I ended up graduating my MSc in Marine biology with some courses from the population genetics programme :) Worked on some projects on a marine research station for a while. And I am now a PhD student, focusing on metagenomics with ancient eDNA from marine sediments in the Arctic. Also recovering from a major burnout. But it's getting better, and I'm slowly coming back to a better balance. It's been a wild ride! Are you also working in science?
@@s.b200 Environmental DNA? That's pretty cool and sort of a new field if I'm not mistaken. Sample collection must be "interesting". I have a degree in a STEM field but ended up doing other stuff. Yeah burn out is a common problem. People become very focused on their study/research and ignore the signs that they need to slow down. Glad to hear you are taking better care of yourself.
Amazing presentation, it was really clear and rich in content. I would’ve loved to have been there, because after the presentation I have many questions that weren’t asked in the Q&A segment: How do they know that the white fenotype came first? How do they know that the yellow and purple fenotypes have the same fitness? It perhaps would be useful to compare and see what flowers do bees prefer the most Do these flowers have ultraviolet patterning? Wasn’t the idea of the genetic pioneers already in the theory of natural selection? Because natural selection would act upon the variants of species and those variants remember me the genetic pioneers mentioned in this talk. How does that concept contribute to population genetics?
I wished you were there because you have some very interesting questions. Especially the questions concerning the bees, because bees are essential in the reproduction (as I understand with my very limited knowledge in biology).
Sorry for the late reply, thought I'd some of my answers for future readers (disclaimer: I'm a biologist but not a plant geneticist!) White first: Not sure in this example, but you can e.g. deduce it from looking at the pattern of mutations in the genes. Same fitness: If one was fitter than the other in their (same) habitat, it would have taken over the other population. Fitness can be defined in a whole lot of different ways, but mostly it's about reproduction. If they existed for >100yrs, they by definition, have the same fitness in this habitat. Attracting bees might not be the only factor important for better reproduction. What if a more attractive pattern was costly in some other ways, like being tastier to herbivores? The bee approach would be the way to go in the absence of the population stability data. UV: yes. Something I was thinking about as well. Darwin: Yes, I think? Not sure I understood the question, though.
Here is just a small aside on which side of the road to drive on. Below are the coordinates of a unique place ( as far as I know) where there is two-way traffic not on a dual carriageway (no median strip) and the rules of the road are to drive both on the left side and the right side at the same time. There are no collisions even though the traffic is continuous and non-stop and there are no traffic control signals such as traffic lights. 19 deg 44.162 min N / 96 deg 11.868 min E
Bees are picky. My great uncle raised bees and it was up in the Grand Teton area. He had Twenty different flavors of Honey. Bees will stick to a certain type of flower. So you got to have several different batches of bee colonies where they meet you will get hybrids because the bees are actively hybriding the flowers naturally.
This video is very interesting, especially if you have been interested in psychology and the relation between psychopathic and altruistic people. They are almost like the yellow and purple flowers. I wonder if it's the same principle causing that segmentation.
a nice presentation, thank you, one small point - I think the mic could do with some high frequency roll off, nothing much to be gained by leaving it open beyond a few Khz, and it will help avoid the high frequency sibilence. Keep up the good work.
I find it hard watching someone explain how the cart pushes the horse. :( [Edit] Ah. Nicely, the Enrico clarifies himself as the video progresses. It's just a little less flowing a delivery at times. Thanks! (For example, the population sampling of dogs *assumes* there is two populations. Resampling over larger data sets will swap the "conclusion" from "no relative divergence" to "relative divergence of 1". Thus it's down to who samples and their opinion on where to draw the line of samples, not the actual real separation or divergence. But then goes on to show the sampling of DNA, which is not arbitrary, they sample the same position/functional genome in each sample)
early on enrico states that the dna moves around and that shows up as colours on different spot of the flower. thought that was due to genes being de/activated.
So you proved bees adapted to any color... now you should investigate how bees handled this situation. Which maybe proves dna is not the steering part but just a library. Rna is the steering part. And it can steer it self and way more quickly.
that desk has likely had more chemical spills, scratches dents and historic dings than any other desk in the world. just how long has that desk been a feature at the RI?
6:08 this woman and her phone omg i would get so tilted if i was presenting my work and people would be distracted with their phones while i was talking..... hmm thats probably because i'd only make a presentation if i truely cared about that topic and i would want others to care, too... idk
I consider the school sign thing more about availability of people selling signs if I make N!-1 signs inexpensively and there is a huge 0 on each sign then evidently people governments etc will have a contest to design a new sign and amazingly my sign with the large 0 will win whether I offered a sample or not. so I sorta don't think that to be a good analogy. when you are speaking of plants why not plot the daughters of first differentiation where the differentiation would be greatest? just thinking out loud here....
This was wholly worthless .... all of the genetic related material was confirmed 20+ years ago and all of the cultural related material was irrelevant to the genetic mutation. What a disappointment that this is representative of this guys life's work. This is equivalent to a secondary school science fair project.
The “genetic related material” presented wasn’t confirmed 20+ years ago: A quick example is the smallRNAs mentioned on the conference, which are being studied intensively today. On the other hand, studying how theory applies specifically on concrete examples promotes discovery and the development of theory itself. Accordingly, the “genetic related material” of this plant species wasn’t confirmed until this group of scientists worked on it. Mendel studied variation on a then apparently unsignificant pea plant, but that study revealed rather powerfully the laws of variation on species. I recommend you to not look down to the work of a scientist so hastily, first search why scientists think this is a really relevant work. And if his work wasn’t relevant at all, why is he presenting on the Royal Institution?
The field of Genetics has been a huge disappointment. For example, geneticists have no idea which genes control height, an obviously hereditary characteristic. Humans worldwide have understood how to breed particular characteristics for thousands of years and have gotten impressive results. Since the field of Genetics arose, humans and biological life in general are devolving and being degraded rapidly. Genetics is just one more religion which interferes with meaningful progress in the world!

Did you get in?
@@s.b200 I'm kinda curious to know what you ended up doing...

Great job dad!
Communication is art.
to Dr. E. Cohen: it takes passion to achieve and communicate such findings, congrats!
This Dr is a great presenter. Soothing

gregor mendel cataloged all of this on his own but here there were 4 different departments involved.
So many ads this is unwatchable
Wow. Snapdragon is the only flower I grow. They're on my balcony as I type. :)
I would find talking to him at a party very interesting.
Brilliant lecture - gave me a small understanding of this complex science.
Good video, will recommend
wonderfully interesting. thank-you.
This video is very interesting, especially if you have been interested in psychology and the relation between psychopathic and altruistic people. They are almost like the yellow and purple flowers. I wonder if it's the same principle causing that segmentation.
Only in a pantheistic universe.
Is there a dimensional model of cooperating universities and success?

Thatnks
Something comes from the video that gets stuck in head for a really really long time.
This Idea has been with me a long time. Anything that can survive will. And sometimes it just comes down to luck. I like dahlias and I don't know why.

.ppl are soooooo. Hi I inbb boo I'm no ok ttrr ry0e
.
i think it is very interesting!!!!!!!
So you proved bees adapted to any color... now you should investigate how bees handled this situation. Which maybe proves dna is not the steering part but just a library. Rna is the steering part. And it can steer it self and way more quickly.
because they are glowing under UV? :D
How much black spraypaint do you think is on that desk now?
Just went to have a look, it looks clean!
that desk has likely had more chemical spills, scratches dents and historic dings than any other desk in the world. just how long has that desk been a feature at the RI?
The woman at that party sounded incredibly boring and mundane
"What's it for?" Stupidest question of all time.
clicked on this expecting a tech video on the company, snapdragon lol
I thought snapdragon was a herb?
6:08 this woman and her phone omg i would get so tilted if i was presenting my work and people would be distracted with their phones while i was talking..... hmm thats probably because i'd only make a presentation if i truely cared about that topic and i would want others to care, too... idk
She was live tweeting the talk!
She was fast asleep in the "Beyond the Higgs" lecture. 😂
Check out around the 38 minute mark. She's proper crashed out. 😴 Jajajaja
I consider the school sign thing more about availability of people selling signs if I make N!-1 signs inexpensively and there is a huge 0 on each sign then evidently people governments etc will have a contest to design a new sign and amazingly my sign with the large 0 will win whether I offered a sample or not. so I sorta don't think that to be a good analogy. when you are speaking of plants why not plot the daughters of first differentiation where the differentiation would be greatest? just thinking out loud here....

Is this coming from the life-size expermient they are conducting right now in Sweden? xD
We need to make sure that the "intelligent design" crowd does not get hold of this video!
Completely lost me at the end. Then when he summarized it's like DUH, why did he even do this talk in the first place? Has he never heard of ecology?

He gets money and honor for work done 20+ years ago by someone else.
