[@chienbanane3168]

Could you talk about how and why the body plan of modern big land predators (big cats, bears...) is so different to that of theropods, the big land predators of the dinosaur age ? Especially, why were they mainly bipedal when their modern counterparts are quadrupedal ?

[@scaper8]

That would be interesting. I never thought about it, but it is kind of weird. I wonder if there's any particular reason for it.

[@somedude140]

Dinosaurs were actually ancestrally bipedal, the ones that had quadrupedal stances only evolved them to accommodate a larger gut for digesting large amounts of plants. Why they were bipedal in the first place I don't know.

[@goodsous]

This is a really good question. Modern bipedal animals are pretty few in number, not counting birds of course. Nearly all mammals are quadrupedal. I hope they have an answer to this.

[@Godzillaaaaa11]

I wonder if its tied to the gas ratio in the air, maybe indirectly metabolism.

[@somedude140]

Grammar Nazi The main reasons are either for tool use (apes) or to use hopping to get around (kangaroos). Sengis are a pretty cool example of a middle stage between a quadrupedal shrew-like animal and a bipedal kangaroo-like animal. I still have no idea why the dinosaurs were bipedal, though. We can be sure that their closest ancestors, the pterosaurs, were quadrupedal; so it had to have been a fairly big detail in what made dinosaurs dinosaurs. Then again, other major archosaur groups like the rauithiscians were bipedal too, so the pterosaurs may have just lost bipedalism. So I really have no idea.

[@nemotyrannus2]

Beautiful and sad real story at once. From the dark , frightening and yet wonderful ages to the slow realization the world has become what it is. Like an old man remembering his lifetime , like closing a book , like a peaceful awaking after an incredible dream... There is poesy and grandeur in this History.

[@notlisztening9821]

the book isn't closing... depending on how we form our future, our species is just a longer or shorter chapter. We might be responsible for a lot of species going extinct but in the grand scheme of things we are just making room for ecological niches to be filled again when we are gone. No one knows what might have been if we were never here or behaved differently and no one can tell if we made the future of biological life more or less interesting. Maybe give it another billion years and after us, a couple more self-aware species evolve and go extinct (or maybe we transcend our biological bodies and become gods? A collective hive mind floating through space as a supercomputer, looking for things to assimilate? Maybe we are just the jumping stone for artificial intelligence, which is an unavoidable step in evolution). I can't really comprehend what you meant with "sad" back when you wrote this and hope you'll learn you look at life in a different way.

Kenneth Satria why could we not replace our teeth if we lost them because of their complexity ? We do it once, after all, don't we ? So why could we not do it more times ? And if my memory is correct, elephants do replace their teeth multiple times (but only to a certain point, making them dying of starvation before dying of old age, TAKE THAT IN THE TEETH, INTELLIGENT DESIGNER, YOU S*** !) If you have any link, it would be nice to share :)

[@sonjavandenende9586]

I'd love to see one on the origin of teeth.

[@kennethsatria6607]

Nathan Jora Maybe because we arent there yet and have hit a roadblock, this flaw only threatens in old age for elephants and by then they would have done all they need to such as reproduce and pass on knowledge... turns out enamel is unable to be remade for teeth somehow and thats the physical limiter. Basically in animals like reptiles its just simple bone structures usually to grind and slice either plant or meat (and for plants only very crudely so herbivore dinosaurs had to rely on the stomach to get the nutrients needed with the exception of duckbills i think cuz they did chew), with us teeth have roots and layers and different shapes and uses. Most animals before and other were all limited to at most two types of simple teeth (and they were comparatively brittle against the elements since they were structured like lines stuck to one another while mammals were interwoven i think)

I LOVE THIS CHANNEL. It gives you an sense of location and historicity and we realize we're but a blink of cosmic time. I'd love more videos on the early humans and the various lineages.

[@danielolsen1348]

Lots of densely packed information, thanks guys

[@RajivKumar-ee7xv]

Liked and subscribed. These are the content I was looking for for many days. It was like a time travel.

[@Platyfurmany]

I so enjoy the story-telling narrative method of presenting this information! We process the information much better when it is presented in such a way, especially if the narrative is engaging, as yours is. And while I am at it, let me also say Thank You, Hank and all of your staff, for all the different channels you have developed to diversify your efforts in telling the story of science in its many different forms.

[@tyresecampbell7507]

Found this channel and watched every video in 3 days. Amazing covent. Amazing personalities as the hosts. Well done.

[@mkhanman12345]

I’m going to do the same thing.

This is a really exciting episode. I know what happens, but I was on the edge of my seat!

[@peter-peterpumpkineater4982]

8:14 one of your cutest videos yet

[@theboyuan0jcfan]

The history of life on Earth is an epic saga stretching unimaginably long time! Even the relatively short Cenozoic Era is so filled with so many events. I can't imagine the entirety of all other ages back across 3.5 billions years.

[@anthonypc1]

btw, love your program, (actually wish our taxes went toward this...) I think some graphics could help make it more clear the order of Eons Eras Periods Epoches Ages you’re talking about. Maybe even a consistent timeline on the bottom of the screen, in scrolling segments like what the Kurtzgezat channel does.

I’d love too see why are appearance changed and when certain characteristics developed I love your channel keep up the great work

[@vincelamb4063]

You mentioned mammal groups that went extinct during the Paleogene. How about making a video on one of them, the multituberculates?

[@somedude140]

They were a strange group of mammals that formed the sister group to the therians (placentals + marsupials). They held niches very similar to those of modern day rodents and rabbits and went extinct for unknown reasons. They may have also laid eggs. That's all I know about them.

[@citiesskyscrapers4561]

Great video as always!

[@xenocampanoli815]

This is a good introduction. Thank you Mr. Green, and to your group of course also.

[@trenpire]

can u guys make a series where in each episode its like a mini-documentary and is a few hours long and talks about a certain period of time like the Triassic or something and all the animals that lived at that time like dinosaurs, giant reptiles and so many more and about the food chain what it was like for the plants how earth was, etc. and than u could go to another period like when the bone-crushing dogs lived or giant bears or mammoths or sabertooths or the largest gorillas/apes ever or titanoboa or giant sloths or the giant turtle or whatever and than do an episode there cuz that would be awesome and then u could do one on an extinction event and it all these episodes would be like hours long hopefully lol or do one of these on a single animal/species like a titanoboa or desmostylia but this one could only be 45 mins long or something

[@Eudaimonist]

One of your best eps yet.

[@manospondylus4896]

0:42 Synapsids/Stem-mammals did not descend from reptiles, they just share a common ancestor with them among the first amniotes.

[@keithdurant4570]

Exactly, I keep telling people that diapsids had not even occurred yet so how could we be descended from them.

[@kennethsatria6607]

Wow i didnt know that... but they were reptilelike right? Something like Dimetrodon?

[@pansepot1490]

Disappointed Turtle, thanks. I was just scrolling the comments to see if someone had spotted that problem. Great channel but sloppiness should have no place in science. Now I'll have to check everything this guy says because I can't trust him anymore.

[@franzanth]

Long ago, "reptiles" referred to any non-mammal/bird amniote. Only later, around the 80s I think, paleontologists started giving scientific merit to those non-technical group names. This lead to "reptiles" being used to refer to diapsids/sauropsids, while non-mammalian synapsids that looked a lot like reptiles were suddenly no longer classified as reptiles. But the public expectation of what constitutes a "reptile" goes way back and is hard to dispel. Even today some synapsid/pelycosaur researchers may casually throw the word "reptile" to refer to Dimetrodon. In my opinion it's the meaning of the word "reptile" itself that has changed over time. - Based on my personal conversations with synapsid workers but mostly Christian Kammerer

[@keithdurant4570]

Franz Anthony Yes it is my understanding that tetrapods diverged into amphibians and reptilomorphs. Reptilomorphs are not however reptilia. Reptilomorphs then diverged again but the only extant lineage is that of the amniotes. Amniotes then diverged into Synapsids from which mammals derived and Reptilia which eventually led to the true reptiles.

[@gabo2161]

@PBS Eons when mentioning CARBONEMYS the background of this artistic recreation shows lepidodendrals, some lycopods that died out long before carbonemys lived. Apart from this small thing, I really enjoy all of your videos.

[@ljgarrison6910]

[@wietsesartsythings969]

Wonderful video, as allways. What I would personaly like to see is more on early human civilisation, stone age and hunter/gatherers type of comunities.

[@TerenceClark]

Yes!!! The Cenozoic! When this channel started and you guys were asking for suggestions this was one of mine. And not that I think you took my suggestion directly or anything, but you did it! And It's awesome. I've always felt the Cenozoic is sort of a forgotten era because it's bookended by currently living species and dinosaurs. But there's SO much in the middle and the closest I've seen anyone get to it is the odd National Geographic program and the Ice Age movies (which surprisingly do an alright job of representing some of the species of the time).

[@helmutmey2014]

So much information! And so much more still yet to learn, I don't mean to get political or controversial here but just stating the facts, it's sad how religion can limit our yearning for knowledge.
