There's an actual Pleistocene Park located in Russia. Its purpose is to introduced lots of large animals into an area and recreate the ancient mammoth steppe ecosystem.
Anirudh Shanbhag not really, the dinosaurs of Jurassic Park are not real dinosaurs. They are mixed with modern animal DNA. Dr. Wu even says real dinosaurs would look differently in Jurassic World.
Most Jurassic Park animals were actually from the Cretaceous. I guess in the same way, many Miocene Park attractions would actually be from the Pliocene ;-)
What about a video that describes the larger extinct portions of the Tree of Life? Entire orders or even classes that just don’t exist anymore. Just a way to show how few types still exist when compared to the rest of time.
Background extinction rate is around 1-5 a year. So multiply that by every year there ever was and then add mass extinctions where up to 96% of all species died and it really is a tiny fraction. Like Dawkins said, there are a lot more ways to be dead, than there are to be alive.(referring to DNA)
the evolution of carnivorous plants would be fascinating. I know a bit how they exist now and the modern benefit to their ecosystems but what happened for plants to evolve digestive enzymes and, for some, trapping mechanisms? What do we know about the ancestor plants? Talk about any, nepenthes, drosera, sarracenia, fly traps, and others please
It took me a couple of weeks, but finally I caught up to the channel! I'm up to date with the videos and it was way worth it. This is without question, the best UA-cam channel ever!
The evolution of that whole order hymenoptera would be fascinating non parasitic descendants of parasitic insects tied up to the evolution of pollination. As for Eusocial behavior interestingly it seems to have evolved many time within hymenoptera somewhere between 8 and 11 times
Science Marches On. I still love the Jurassic Park novel though. You can tell the author did his research. As mentioned it was state of the art for the time,but as mentioned Science marches on. One of the things I liked about is how it pointed how little you can about behavior from fossils. We try to make our best guess based on bones and, footprints and so on but it's so little compared to a living animal. I thin that's why extinct animals fascinate us so much because there's so much we don't know. Like wise when he took liberties on the animals behavior and biology I like how most of it was based on parts that don't easily fossilize. So on one hand obviously there was no evidence for it, and it was OBVIOUS artistic license but he also took care not to contradict the existing evidence at the time as well when he made stuff up. I found that an interesting way to do things.
I just wish we got to see the River Boat on screen. I know they based the one scene in JPIII off it, but in the novel, the riverboat scene was absolute terror. Not to mention the Waterfall scene. Chills all night from those scenes...
Reverse engineering is the key. By switching on and off genes in chicken embryos, scientists have grown tails and teeth in early stages. So... a Chicken Rex would be pretty cool
Omg can’t believe I only now found this channel! I’m a second year geology and paleontology student so all these video’s are right up my street :D nice work! My professor told me briefly things about decaying dna and the readable limit already, but this goes way more detailed, thanks. Earned a sub!
That would be fantastic!!!!!!!! I think it gets really interesting in the Devonian when you have a whole bunch of proto-spider ancestors and spider-like relatives like trigonotarbids.
Don't forget the DNA obtained from subfossils of glyptodonts, which proved they were actually nestled within the armadillo group, and various south american hooved mammals, which proved that not only were they monophyletic but also that they were closely related to the odd-toed ungulates.
@@heanstone1327 Basically, we found remains of some extinct south american animals that still had enough genetic information for basic molecular testing. Glyptodonts were large herbivorous animals with giant shells, like an armadillo's but inflexible. They were previously believed to only be related to the armadillos, but the tests proved that they actually were armadillos themselves. South America once had a large and diverse assortment of hooved mammals, from the rhino-like mixotoxodon to the rabbit-like pachyrukhos. However, most of them went extinct 3 million years ago when the isthmus of Panama formed, connecting the Americas and introducing other animals that out-competed most of them. The remaining ones, mainly larger forms like toxodon, went extinct 10,000 years ago when humans entered the scene and hunted them to extinction. Because we never had any actual DNA to work with, figuring out which groups they're related to and even how they're related to eachother has been extremely difficult. There were even doubts that they were closely related to eachother at all. We knew for sure that they were placental mammals, but that's about all we were sure of. Until we found several remains of mixotoxodon and the camel-like macrauchenia buried in caves previously inhabited by humans. The testing showed us that they were closely related to eachother and finally solved where they belong on the family tree: next to Perissodactyls/odd-toed ungulates (modern-day horses, rhinos, and tapirs).
In this episode there is one of the things I love about this series and the narrators: a reasonable open-mindedness that allows for a scientifically appropriate balanced skepticism not found so often in science minded folks; the type I call "science dogmatists" who arrogantly believe that currently accepted science is set in stone and cannot be questioned, which ironically demonstrates a lack of understanding of how science works in the first place. Thank you to the Eons team for great content and interesting delivery that often leaves you thinking about what the future will bring. Keep up the great work!
This channel is EVERYTHING I ever wanted. I love anything to do with prehistoric life, but especially pre-Triassic and it’s rather hard to find engaging material for it. Anyway, I’d LOVE an episode on anomalocaridids and/or lobopods, or something perhaps on the Snowball Earth hypothesis. Thanks for the amazing content!
would you ever do a video covering the evolution of certain soft tissues, such as ears or cheeks, lips, even tongues? I was wondering a few days ago about which dinosaurs had cheeks, and how we know. I have seen some recreations of T-rex with lips covering its sharp teeth and I wonder how accurate that is.Thanks!
@@shersockholmes6261 There are reptiles with both cheeks and lips, but regardless consider that birds are the most closely related living animal to dinosaurs and they don't even have teeth. You wouldn't conclude from that that dinosaurs didn't have teeth

(Which also applies to how we research paleontology/archeology, too!)

Hi Eons! Great vid! There is some older DNA that has been sequenced though. Partial DNA has been sequenced from Magnolia and Persea from the Miocene of Idaho (Kim et al. 2004).
Best science channel on UA-cam. Always great videos. Presenters are always great and enthusiastic about what they're doing. I've learned more about our past from this channel, then I ever did in school.
"bone DNA better preserved in permafrost than previously thought, possibly storing readable pieces for up to a million years" another reason to stop global warming All this information really definitely helps people who wants to become paleontologists, keep up the good work
Global temperature increase melts the ice , and makes such fossils much easier to access. I would argue in many if not 90% of cases, such fossils would never be discovered if it wasnt for the ice melting and exhuming such fossils

Just wanted to say I really like the speakers you guys have here. Not only this girl, who is awesome btw, but also the other guys. Every one of you is nice to listen to. Not overly hyped or rushed, good tone, the perfect touch of humor next to alot of info. I frigging love this channel, while already being a long time sub to sister channels.
I love this channel. Among many, one weird reason for that is because the positive way you tell the story of the past. If I ever need to hear life altering information, (ie. Death, tragedy) I wish you all would be the ones to tell me.
there are a few errors in the illustrations here. half the animation for the pcr is the wrong way around. dna polymerase only works in one direction and the two strands are antiparallel. also there's an agarose gel in the picture of uv light. in this context the uv light is used to detect dna, not to destroy it.
I’m sure you’re correct but I don’t think many of the people watching this video could recognise the difference or care anyway. It’s not like this is research material. Most people are here for the basic explanation.

Makes me wonder, with Moore's Law in mind, if we might one day be able to reverse engineer ancient DNA from a sufficiently large sample of the proteins it was coded to create.
Moore's law has already failed, at least for now. And... I don't know, it seems to me that that would create DNA of limited usefullness. It wouldn't have any junk DNA to do molecular archaeology on, and... I don't know how it could ever be complete.
Will you guys ever do a video on Speculative Evolution? Predicting how organisms might evolve in the future after we are gone, based on what we know now of plate tectonics, climate, and past organisms? I'd love to see your take on it!
Great stuff as always! Could you talk about how old hive insects like ants, bees, and termites are? How did they evolve? Did there ever exist any super weird ones that we wouldn't recognize today?
I'm confused about the process of preservation I guess. I thought that fossilization was the process of replacing every organic molecule with an inorganic molecule, i.e. mineral, turning the organism to stone. So I don't see how we could ever have "fossilized DNA". Seems like it may be possible in a case of partial fossilization but would only be possible in most cases for other types of preservation, mummification, freezing, sealing in amber, etc. Has actual organic DNA been found inside mineralized bones? Can anyone clarify?
Yes I think you're right on all counts. That lack of specificity is what makes it confusing. Though no one would be looking for DNA from trace fossils. I wish the Eontologists here would clarify.
What I think is amazing is protein-to-RNA reversion, they grabbed a protein, turned into RNA and then did genetic comparision. They did this recently with South American horses and South American ungulates like Macrauchenia. So now we know for instance the closest relatives to Macrauchenia are perissodactyls. I think it's fascinating. This video is great. Well done!
I want to know: What does PBS Eons want to know? Do an interview of the entire regular crew about their favorite upload so far or what they are or would like to do for a future upload ;) That would be really interesting IMO. Go full untethered nurds unleashed please! -Jake
Sadly, it's largely a mystery since bat skeletons are fairly frail and rarely fossilize. There is also some controversy in bat phylogeny, so really it's all a big mess. Although they are really cool.
@@somedude140 All the more reason to do a video on it. The competing theories, evidence for and against each, etc. They've do it with other controversial/uncertain things on this channel.
You could probably piece together older DNA by preserving metadata such as the location of each molecule in the sample and the compounds around them, then use a computer model to reverse engineer the reactions that occurred. Similar things have been done with larger structures, like galaxies, the solar system, weather patterns, tectonic movements, ancient collapsed buildings, plane crashes, etc.

Seems like it may be possible in a case of partial fossilization but would only be possible in most cases for other types of preservation, mummification, freezing, sealing in amber, etc. Has actual organic DNA been found inside mineralized bones? Can anyone clarify?

Can you please talk about dating of rocks for example how old sediment is.
I wouldn't recommend dating a rock. I got nothing but a stone-faced look all night the last time I tried.
Good stuff. As an ecologist I have a great amount of interest on the subject but limited knowledge :)
They’re already bringing extinct animals back to life in 2020 they’ll be bringing mammoths 🐘 back👍🏻
I think the recent progress in AI can help out with this question in the near future.
I love this channel so much ♥️
waiting the day i get to see a live mammoth
Yes but No.
Nope but Hell yah.
That how science answer your question!
Do a video on the evolution of metamorphosis.
Make sense of how caterpillars, tadpoles etc evolved.
I love pbs
Thanks, Steve.
You want Kaiju? Because this is how you get kaiju.
I missed the gang last week. Don’t ever leave me lingering for a new upload again. Now on to the video!
I want to know: What does PBS Eons want to know?
Do an interview of the entire regular crew about their favorite upload so far or what they are or would like to do for a future upload ;)
That would be really interesting IMO. Go full untethered nurds unleashed please!

I love this channel! Always great to watch!
Bats! We'r on Spooky Month, we need BAT EVOLUTION!
Sadly, it's largely a mystery since bat skeletons are fairly frail and rarely fossilize. There is also some controversy in bat phylogeny, so really it's all a big mess. Although they are really cool.
@@somedude140 All the more reason to do a video on it. The competing theories, evidence for and against each, etc. They've do it with other controversial/uncertain things on this channel.
Yeah, and they do it pretty well
I, for one, approve with genetically recreating ancient animals, YESIVESEENTHEMOVIES, I think we can accept the risks
I dk how I feel about being so early to a PBS video....
it's kind of weird
i said the same thing about cumming in my girlfriend heheh
The trend is to comment "First!" unless you want to be different. I see you chose to be different
Feel sexually aroused.
You could probably piece together older DNA by preserving metadata such as the location of each molecule in the sample and the compounds around them, then use a computer model to reverse engineer the reactions that occurred. Similar things have been done with larger structures, like galaxies, the solar system, weather patterns, tectonic movements, ancient collapsed buildings, plane crashes, etc.
The velociraptor @ 10:35 has broken his wrists :(
Excellent topic. Love this channel. Would love to do a feature article soon about this very topic.
