Chinese Fossils Reveal the Evolution of Mammals | SLICE SCIENCE | FULL DOCUMENTARY 

True: early pritomamalian, like the Dimetrodon, and even more with Gorgonopsids already had differentiated teeth's and the Cynignatids almost a complete mammalian structured mouth, including cartilagineous nose.

Yes, but these mammalian-like synapsids were not prevalent until the Triassic, not the Permian.

At least 318 hey, U sure it wasn't 293 or 345 or or....

@@SteveWarlee Haha, oldest definite Synapsid fossils are from 318 million years ago. They could be older, but older ones aren´t found (yet). So yes, at least 318

@@asthemoonturns Yes, I posted a similar remark. That "mammal-like" descriptor is like a sloppy, 1950's vintage "Mutual of Omaha" text. It was never accurate, for anyone familiar with the grand phenotypic sequence of complex life. From the early years of paleontology, it was understood in broad terms that a gilled, fully aquatic ancestor became-- ~ a lung-lobed, contingently pond-loping pioneer, ~ then an opportunistic amphibian tetrapod, ~ one of which continued evolving the first amnion, permitting a fully terrestrial, amniotic tetrapod. That moment represents a substantial cladistic departure in vertebrate potential, as well as a very poetic pivot and a quite literal watershed in our evolutionary archive. Far more momentous than slow, incremental features of classic selective change, the acquisition of an amniotic membrane in an architecturally sturdy, gas-permeable shell was a genuine phase transition, fostering synergistic features as momentous as ~ ~ the earlier emergence of the nucleus in eukaryotes, and ~ subsequent pioneers in cell massing, fostering colony-obligate cell families and structures, and then, ~ another phase transition: the stunning powers of cell differentiation & migration potentiated a full "conceptus-to-birth" embryogenesis within a rent-free placental "island," with a uterine communication as sophisticated as the blood-brain barrier: in with the fresh, out with the stale, and voila! Look, Ma! The metazoans are efflorescing! Of course, Ma knew that before anyone did, and eventually, viviparity displayed many benefits over ovoparity, but also introduced new problems, like squeezing a big brain through the narrow canal and mandated by bipedality, As mammalian gestation addressed those new challenges, the solutions began to look like good fortune rather than bad luck: neoteny, or extended childhood, soon permitted even bigger brains by stretching out the time they needed to grow, which vastly enlarged the window of learning from grandparents, tribal leaders, experiential skills and older siblings. Evolution often looks less like a linear trail of advances and more like a spiraling compromise, an Hegelian see-saw, letting a delinquent dialectic apply for new jobs that reapply old skills. Such flexible winnings begin to resemble: * self-reflexive consciousness, * self-reflective intentionality, * syntactical language, * abstract ideation, * extra-somatic information storage, * technological innovation, * competent urbanism, * empathic, pluralist societies of deep equanimity, * the extensive, intensive education of a scholarly sector, the set of industrial innovators, a class of skilled political and diplomatic agents who establish both internal and international equilibrium for the maintenance of economically vigorous, intellectually generative, socially diverse and tolerant civilizations. Hmmm! Not bad for a recently brachiating knuckle-nose who couldn't even fry an egg, let alone trade one for a waterbed.

Not really fossilized soft tissue protiens ruins all of this. Proves not much of this is remotely true

Don't tell me, liar for the baby jesus? ​@@vikingskuld

@@imwelshjesus your the one lying or just ignorant of modern finds. Either way your criminally ignorant.

@@imwelshjesus Was that an evolutionist refusing to admit that we were once like rats climbing trees and eating crunchy insects ? lol.

The claim that "other animals only have one kind of tooth" is pretty bogus. Take tyrannosaurus rex, for example, they had differently shaped teeth in the front of their jaws compared to the sides. Pretty sure there are other examples of reptiles, fish and other animals with varied teeth.

Finally, basing our theories of the ancient fauna on fossils is a big mistake. The fossil record is seriously lacking. We have NO idea of how many types and how many of each type actually existed. Fossil bias is a thorn.

Another millenial using the falsehoold "A.I." at every sauce. This is no AI, there is no AI. The whole fraud is just marketers and IT journalists who are fraudulously using sci fi denomination for something that does not exist in science. It's just computer algorithms, yes i know it does not Jive and swings like using false words but i dislike frauds.

hahaha or rather its ancestor.

I.e. Termed the Cambrian Period and referred to as the "explosion of fully formed life"?

​@@JohnKSedorthere's a period before the Cambrian...but he means complex life from inert matter. Watch the video from the channel: Hoover Institution *Mathematical problems with Darwin. It's pretty eye opening.....if you're curious.

Do you have any evidence for some magical being talking life into existence?

and naps are most important throughout the day.

😄👍🏻

Agreed. I gave up on this video at that point. It's so disheartening to hear these scripts confusing things so badly. Whydo that? It's not much more complicated to get it right. It's more interesting to get it right, and doesn't require people unlearn things later on.

So we have egg making mammals before placental mammals ? Imagine women making eggs like chickens. lol.

​​​​@@ericastier1646Then instead of having to choose between having a baby or having an abortion, a woman could make an omelette. Call it an Ove Maria.

@@Unit8200-rl8ev That's vile and repulsive evil thinking.

​@@ericastier1646... And f'in hilarious!

Natural World Facts is great at posting captions, species names. Also Astrum.

Yes. I also like timelines and cladograms. Leave them a little longer.

There is no doubt that with greater computer and graphical power, presentation skills have degraded. If you watch the militrary training on flying instruments in the mid 20th century, the clarity and methods of presentation and animations were incredibly stunning and efficient at teaching. An art lost by now.

I had a mixed response to the 3D animations. in itself good but I wished the paleontologists didn't have to play fake that they could see the animation, i found that a wrong note because it is deception, they could not see them and were pretending. I guess 3D holographic animation is still not in existence yet. In the 1990's we had static holograms that used monochromatic laser to give stunning real 3 dimensional view over a limit angle using photo lithography. We are still waiting for the 3D animated holography that will replace our computer monitors. It's not happening yet.

Well there are the 3d video goggles you wear with strap around your head used with play stations or plugged into computer's that have 3d video displays.Older version's with trick stereo photographs and basic lenses that you hold up to a window provide impressive high definition 3D from 150 year old photographs.Just Victorian parlour tricks150 years ago. Sure the hdwr has been updated but the science has been known since Isaac Newton's time in the 16 th century 😮

@@jazzrossy930 No that is all stereographical images or videos not 3D real hographic objects projection . including google glasses it's not the real thing.

My comment was not about the cartune. It was about your comment (unedited original) that 3d stuff wasn't even valid and it doesn't even exist. I beg your pardon if I misinterpreted your response.

The „when“ may not be exactly answered, but the „if“ can be answered! 🎉

Thank you for watching !

Thank you !

It makes sense that they survived the cataclysm and the dinosaur didn't victim of their own success that lead to gigantism and dependancy on large regular food intakes to support themselves. Size matters. Being satisfied with insects and fruits is an advantage.

Welcome !

tell that to turkey vultures

You probably didn't miss much. The Chinese are not as curious about archeology as us. You'd probably would not have seen much if anything.

Thank you ! 😍

Don’t project your ignorance on other people.

​@giannapple I was typing the scientific explanation but deleted it after reading your reply. 😅
