Correction! At 9:19, we erroneously refer to Dimetrodon as an herbivore. It was definitely a carnivore. We even made a whole video about Dimetrodon and their carnivorous ways in a previous episode: kzbin.info/www/bejne/iYOWgIKGbtJ8o6s Thanks to everyone who pointed out our error!

Please cover the early evolution of primates, including strepsirrhine evolution. Discussing the Ida debacle would be good to discuss. Also, please discuss the giant, subfossil lemurs.

[@puncheex2]

What's a sub-fossil? The "Ida debacle" was a museum-media hype-money mistake, not an event that said anything about the paleontology. But, yeah, primates.

[@LemurWhoSpoke]

puncheex2 "Subfossil" means younger than younger than 50k years. Basically not old enough to have become rock. Pleistocene megafauna fall into this category, but few shows have ever talked about the giant lemurs, which are called "subfossil lemurs" in the literature. As for Ida, there was a lot to be learned from that debacle. Basically a small group of paleoanthropologists was trying to push an outdated view on the evolution of primates. The reason it took off wasn't just because of the chance to make money. The outdated view of primate evolution is still very much alive and can be see all over signs in zoos and in some general textbooks. Basically they tried to claim that Ida was a lemur, and a missing link between lemurs and anthropoid primates. No such missing link exists because anthropoids didn't evolve from lemurs. In fact, this is tied to an even bigger upheaval in our understanding of primate evolution. Primates did not originate in Africa; they came from Asia. In fact, the earliest fossils in Africa had long been labeled as anthropoids (by the same group that gave us Ida), but have recently been shown to actually be stem strepsirrhines. The early monkeys first started evolving in Asia and were probably nocturnal, whereas the lemur ancestors evolved in Africa and were diurnal. That's big, and an episode should be devoted to it.

I bloody love this series. Thanks PBS!

[@yvonnerogers6429]

Thanks for this amazing video! I've watched it several times at this point, mainly for the science and history, of course, but also because the music for this one is AMAZING!!!! Thank you, APM, for helping to make this such a memorable learning experience! I love this channel so much!

[@captainthrall]

I could listen to you talk all day long. Thank you.

[@BRUtahn]

What an awesome video! I love how you guys help put things in perspective!

[@ericanderson1846]

Spectacular explanation. More of this, please.

[@jlh8830]

Me and my 5yr old son always start and end our day with a little EONs. Great job guy/girls keep up the great work.

[@CompBioQuest]

I love the illustrations and storytelling. Thank you

[@67comet]

I usually listen to these while I'm at work. Keeping the window in the background and just listening. BUT, when Kallie comes on, I switch it to the front, because "KZbin Crush" .. She's a good speaker, speaks clearly, and has a good vibe about her subject matters.

[@moiraandnica4798]

I really enjoy your channel! I even let my kiddo watch with me! Thanks for explaining things like this, really appreciate y'all. ^_^ :) :)

[@robyn00xx]

This is my favorite channel to watch after a few bong rips

[@bjarkiengelsson]

No kidding!

[@Argethebarge]

Love it. Glad that you guys try to keep people engaged in palaeontology!!

[@judychurley6623]

One of the best overview videos in the series. Gives a great picture of the period.

[@danm7298]

I love learning about how life evolved from basically nothing to where we are now and where we are going. It really trips me out

[@maidros85]

Holiday is when that KZbin bell brings you a notification of a new Eons vid. 💕

[@yvonnerogers6429]

I’m loving this channel. Thanks for all your hard work! I learn so much! I wouldn’t mind a video like this covering the Cenazoic from the Paleocene through the Pleistocene as I find that stretch of time doesn’t get covered much, either, at least not as much as the dinosaurs’s era. By the way, the soundtrack for this episode is beautiful! Kudos!

[@brooklyna007]

This was so awesome! Thank you.

[@P-Bean]

I've learned so much more from this channel than school about this kinda thing.

[@wade5941]

Nice video and well done. I have always found it interesting that the Cambrian explosion of life occurred during a period of Earth's history that coincided with CO2 levels of approx 4000 ppm and temperatures 15 degrees C warmer than today. It is also notable that temperatures have almost always been significantly warmer than temps today. As she said, almost every major group of animals that exist today developed during the first 40 million years of the Cambrian. Suspect there was not much ice at the poles and that ocean levels were much higher than today. Also interesting that the Permian extinction coincided somewhat with historically low temperatures and CO2 levels. So many changes through time. So many variables.

I love you mention the trilobites. I have a trilobite collection! They are amazing creatures and is it weird that I find them adorable?

[@mezo4010]

Nope.

[@nicolel.2398]

Dude trilobites are the cutest things that ever happened. I love them so much.

[@EvilSnips]

Yessss :D I have seven trilobite fossils xD Most of them are actually really cheap, so it is easy to start a collection. Just go to a local rock shop.

[@nicolel.2398]

That’s radical man, I love it. I’m in college for paleontology so I have some wonderful outlets for trilo purchasing ❤️

[@EvilSnips]

Paleontology sounds like a fun major to take. I have been considering it, but it's a lot of field work from what I have seen.

[@Kotorichan]

Eons made an earlier video presented by Hank Green that explains how the Cambrian extinction never actually happened... so it would be a good idea to relate to that video when she says "it is not well understood". Keep up the great work :)

[@Chris-hp9be]

"The Great Dying" sounds like an episode from Game of Thrones

[@lucasotis9525]

The music and pacing in the beginning to hype up the viewer is gold, fantastic editing

[@noeditbookreviews]

What a time to be alive. For 99.99999% of the history of life, nothing had any understanding of its origin, and so recently along comes this primate that not only invents the question but the obsession with answers. Now, today. I can just pull a device out and look up what life was like millions of years ago.

[@Fatheroftheclones]

I look away for one minute and the fish already have legs

[@deebee5378]

I'd like to see some information on what may have led to today's monotremes like the echidna and platypus.

[@fadiljo4520]

What I concluded from all of this is that life always finds a way.

[@thomasdykstra100]

The "Cambrian Explosion" was a "Great Dying", evidencing the decimation of lifeforms present at the time of the Great Flood judgment... The sediments containing this prodigious range of creatures is obviously a death collection, gathered fairly quickly under catastrophic circumstances. The fossilization processes depended upon these unique circumstances, and owe their efficacy to the one-off chemistries brought about by a globe in wholesale turmoil.

[@Replicaate]

Trilobites hangin on like that "I'm not dead!" guy from The Holy Grail.

[@nescaudrummer]

the album "Phanerozoic I: Palaeozoic" by the band The Ocean made me interested about the topic, so I'm checking out this video

[@joenotch7429]

Watching this video 2 years later and FINALLY someone mentions The Ocean.

[@vmites7100]

The old days of Earth is so facinating...It seems so innocent and beautiful

[@xxxtakaji-kaixxx9016]

Cambrian explosion:we wish to come back but we can’t 2020:WRITE THAT DOWN WRITE THAT DOWN

[@mrx4022]

Fun fact: Dimetrodon is a stem mammal, meaning mammal like reptiles which includes Ssynapsids, the family which you and me are in. So, evolutionary speaking, Homo sapiens and Dimetrodon are very, very distantly related

[@luciusgracchus]

To be honest the dinosaurs are kind of boring at this point. Paleozoic era is full of exciting topics: extinction, first plants, first land plants, first land creatures and generally first of so many things. Good thing PBS Eons highlights this. Keep up the good work!
