They also tease us with -gorgonopsids added -gorgonopsids removed in the patch notes. They do this every update with a strong build that was previously removed like come on! Last time it was -tyrannosaurus added -tyrannosaurus removed Give us a break devs! Stop making me salty!

@spindash64 4 года назад

Rexie’s ban was at least understandable: the Saurapsid meta had turned into a game of just trying to max out your base stats, and got kinda stale. The Cenozoic, while facing an even more OP build, at least has a more interesting dynamic that forces more unique stat spreads.

@puncheex2 6 лет назад

The problem there is that neither of thise structures fossilize well, so what is known is from the very rare fossil find and extrapolating from what is there today. Alittle reverse-engineering helps too. We haver today a lot of example of eyes from the miniscule to the eagle, but that's now - what was in use in dinosaurs, for example, is to an extent a guess.

I don’t know. I think the Precambrian contains potential extinction events that make the Phanerozoic ones small. Granted, all we had were microbes. Great video!

@Darkstar..... 6 лет назад

Steven Baumann she also mentioned exciting and cruicial changes. Microbes would be in numbers far greater. And if they were wiped out thats the end of the story but it was over a far greater time span that any changes happened when your barely a multi celled organism.

@stevenbaumann8692 6 лет назад

aussie oi oi oi I generally agree. I just did a geo rant where I identify at least 3 possible quick Precambrian extinctions. 2.4Ga, 1.85Ga, and 1.086Ga. It seems no one has bothered to explore this in detail.

@noctusowl 6 лет назад

You are right. The great freeze or Snowball Earth around 700 million years ago probably wiped out 99.9% of all life existing by then. There might have been other similar but less severe episodes.

@stevenbaumann8692 6 лет назад

noctusowl exactly. I have 3 others in mind. 2.4 Ga, 1.85 Ga, and 1.086 Ga.

@superdumpfback4041 6 лет назад

Are you referring to the oxygen crisis? The oxygen produced by cyanobacteria slowly concentrated in the oceans 2 billion years ago and led to the extinction of many other organisms. Oxygen was a cell toxin for most of the early microbes

@LemurWhoSpoke 6 лет назад

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 6 лет назад

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 6 лет назад

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.

OK, thank you for the courteous re[lies. I appreciate the education you have given. I agree that this would be a very good topic for Eons to spend some time on.

@LemurWhoSpoke 6 лет назад

puncheex2 No problem. I just hope the Eons staff see this and consider it. If they do... I volunteer to help write the script(s). I wrote the Wikipedia articles about lemur evolution, lemurs, and strepsirrhines. I also have a lot of good contacts.

@GotPotatoes24 6 лет назад

Maybe in the same video, or maybe in another, I'd love to see an in depth examination of hominin evolution- the news that indisputably Neanderthal rock art was found in Spain might create more interest in the topic of archaic humans!

@yvonnerogers6429 5 лет назад

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!

I really have to say, this is one of the best channels with the most interesting subject matter I have ever found on the internet. The presentation of the wealth of information is absolutely incredible. I have grown an entirely new appreciation for life on earth. I knew life on earth was something special and unique, for some reason I never realized just how /cool/ it is. These videos have given me a feel for evolution that I've never had before. Seeing how life evolved to take advantage of the environment, and how intertwined it is with geology and other creatures is remarkable. I can't get enough of the fossil record!

@stevesellers-wilkinson7376 4 года назад

I'd love to see more about shark evolution and the chondricthes in general. Your videos are brilliant, by the way! I'm a huge fan!

Eons has such fantastic background music. It really helps to set the mood and carry the narrative along...

@Kotorichan 6 лет назад

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 :)

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

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 6 лет назад

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

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.

Props to you, lady! Of course I'll put it in my own words and such, but I will give your youtube a credit as well. (Since I have to record my findings anyhow lol.) Very much appreciated. You're very much alike my Earth and Science teacher as well.

IDK about the first 0:40 seconds. When I was a kid I never cared too much about the parts in my natural history books about dinosaurs. I was always infinitely more fascinated by the pages about the Pre-Permian Paleozoic but more than anything else the Cambrian. I would glance over the dinosaurs and go yea that's pretty interesting but stare for hours at the artwork about the Cambrian.

@dillon1455 5 лет назад

I would like an episode of the start of civilization. I think an introduction of where we came from; Homo, and the possible parents of us like the Denisovans, and then how we banded together to cultivate and then conquer would be fascinating due to the fact there there isn't much touch on here on the ages. Also, I love PBS Eons because you have taught me so much in so little time. I greatly appreciate all that you all have done to make this available. I will contribute, monetarily, when I can afford it. Thank you, PBS and Hank especially because I watch him every Saturday to teach my students on Crash Course about the Anatomy and Physiology of the human throughout our Medical Assisting Program. Thank you, all, very much!
