Sorry for once again a month without a video. I never did speculative evolution before so this was a new field for me.
It's fine I still get to hear that sweet sweet voice either way.
To be honest, I really don't think it would have been very possible, due to the changes of thr Earth, the available land to live on, as well as the many different species that would still exist. I feel as if humans would have to work their way around them, but they still could survive.
I still fell that they would either be used as food, or as apart of military riders.
I still believe that we would be the biggest and baddest species.
Oh, and here is a good video idea. What if the United States had joined the Triple Alliance during The Great War.

And the two other Permian extinction events: Olsson's extinction at 273 mya killing the pelycosaurs, and the end-Capitanian extinction event at 260 mya killing off the dinocephalians. The latter was in som respects as bad as the mass extinction at 66 mya.
@@king_halcyonAnd end-Ordovician, another extinction worse than the asteroid 66 million years ago that killed off, among other things, the animals mentioned at the beginning of the video.
There's also the end-Triassic exinction, probably even more responsible for the rise of the dinosaurs than the Great Dying. Without it, Sauropods would just be one group of giant herbivores competing for environment and theropods would stay small predators.

I think this my favorite video so far. From about the age of three, I had an unhealthy obsession with dinosaurs and prehistoric creatures. It kinda faded into the background as I got older but it was still there. This video helped me rediscover my love for these fantastic beasts for lack of a better term. Thank you.
I was just reading new dinosaurs by Dixon and more alternative prehistory is really cool for me right now. Great stuff, cheers!
Awesome book
11:17 so they would've evolved into some weird off brand sangheli? (elites from halo)
Looks like if a sangheli from the halo legends arbiter short had nosferatu teeth
coderedcomputerguy the little guys can turn into ungoys and kig yar
Blargh
Unlikely since the Unggoy and the Kig-Yar evolved on entirely separate planets from the Sangheili. The Kig-Yar are more avian than saurian like the Sangheili, and the Unggoy are sort of like crustaceans with their hard exoskeletons. Plus, Unggoy can’t even breathe oxigen. They breathe a methane-rich gas mixture through their gas-mask like breathing apparatus since they’re the only species in the Covenant that can’t breathe the same air mix as all the others.
As a paleo enthusiast who also loves human history it’s great to see you talk about both. Keep it up! I’d recommend if you were to do another thing like this I’d learn about war between the Arthropods vs vertebrates. Maybe do what if the Arthropods won the evolution war? I’d maybe use the Devonian to start as that was the turning point leading reptiles to rise as the oxygen rich planet drys out and cools, maybe make it so earths climate never changes therefore not causing the Arthropods rule to not decline (land nor sea nor air)
I'd say that an alternate Cephalopod world would be far more intriguing.
"The Great Dying"
What a name for an extinction event
It puts the asteroid impact into perspective, doesn't it? The Cretaceous-Quaternary that wiped out the dinosaurs was one of the five big ones but it's around #4 in severity. End Permain, End Ordovician and End Triassic were worse and the End Devonian was almost as bad). The dinosaurs actually benefited from two different mass extinctions : the End Permian that wiped out dominant synapsids giving diapsids a chance to radiate and the End Triassic that wiped out the rival archosaur lineages like the aetosaurs, phytosaurs and rauisuchians (look up Postosuchus if you want to see a Triassic apex predator - basically fast land crocs - Triassic fauna is weird) that left them the dominant terrestrial animals but the non-avian dinos were killed off by a third.
But the tenspids survived the Ulavavian Period and therefore gave history of humanity today a quick turn to the light side because of tenspolorians laying eggs then evolving to ulumpians.
This brings me back to something similar.

Heres a new video idea that has to do with this video topic. What if an extinction event like "The Great Dying" or a giant asteroid happened again what creatures would survive and which would eventually take our place at the top?
I want to see this
Probably reptiles or birds. Or who knows? Maybe the geography of the planet changes as sea levels rise leading to a world dominated by aquatic animals like fish. I am no scientist but it is worth exploring.
Too late Earth is already in the midst of the Anthropocene mass extinction though this one is more similar to the mass extinction in the great oxygenation event as it is evolution stumbling on a lifeform that causes a paradigm shift in the environment causing it again, you might know it, they walk around on two legs and build stuff all over the place while setting fire to just about anything they can get their hands on alot messing up the composition of the atmosphere in the process.
Well said.
NASA would be given all of DOD’s (Department of Defense) funding and would put humans on Mars in a fully functioning colony to prevent our extinction.
If they had 65 million years to develop then one of the dinosaur species could have been an intergalactic species by now
We still have dinosaurs today. They're called birds. They have been evolving for the past 65 million years. The smartest birds are crows and ravens. If there wasnt a mass extinction at the end of the cretatious, then non avian dinosaurs would have lokely continued to evolve to the level of crow intelligence at this point in time.
Press F for the V'straki
#hehe
No, it wouldn't. You need an energy surplus to even reach the level of ancient societies like Egypt. Dinosaurs did not have such. Intergalactic travel, at least outside of a local group at the most generous, is impossible because of the nature of the expanding universe.
Not inevitable
I really like this new style of video! Well done!

It isn't how evolution work. Humans have relatively short history. Our specie has only three milion years and evolved from something what was basically a chimpanzee what has between 4-6 milion years and didn't change much from time humanity separated from our common ancestor. There are unique reasons what decided on human evolution (I'm not talking about aliens before some idiot say so).
@@TheRezro Its a Star Trek reference
I see you are a man of culture as well! That Voyager plotline was honestly weird AF.
This video absolutely intrigued me, especially with your short image of a dinosaur-humanoid right near the end. As such, I went and did a little light research and math and have discovered that there is another even more curious alternative chain of events.
I started under the assumption (a very large assumption) that the Suminia or similar creatures may have undergone evolutionary pressures that eventually resulted in a human-like intellect and use of tools. I then took the time-span from the first emergence of primates, to humans, and then the modern day, and was correct in noticing that this interval was far smaller than the time between the Permian-Triassic extinction event and the Cretaceous-Paleogene extinction event.
Taking the Suminia to be a parallel to the very first primates, it turns out that they, or similar creatures, could surpass human levels of technology in as little as 68.5 Million years after their, in our world, extinction during the Permian-Triassic extinction event. In fact, they have a margin of error of roughly 2.7 times, meaning that even if they evolved to our level of technology 2.7 times slower than we did from the first emergence of primates, they would still have sufficient technology to potentially redirect the asteroid that caused the Cretaceous-Paleogene extinction event, thus that extinction event may never occur in their world at all.
It's a very simple set of calculations that I've made, but I've put them up on pastebin for those who want to see it: pastebin.com/KGrHeHfL
My inner sci fi storyteller enjoyed this comment
I love you for this quote at 3:50: "The common conception was that mammals simply appeared out of nowhere during the jurassic"
This perfectly embodies my frustration with pop-culture palaeontology and biology (even in schools)
So thank you very, very much for making this video and sharing the fascinating creatures that are the therapsids (and mammals for that matter) with the world!
I love your stuff, and knowing a few people who aren't into evolutionary history like I am who watch your videos, this has really let me have some awesome discussions with people on the evolution of life on Earth. So thanks for that!
If the volcanoes in Siberia didn't erupt at the end of the Permian era, would they inevitably just erupt some time later?
Probably, but the Siberian eruptions had a bunch of factors that made them unusually lethal due to the surrounding geochemistry and minerals (they emitted huge amounts of natural CFCs, for example, which probably wiped out the ozone layer for a while). By contrast, a somewhat similar-sized eruption happened in North America around 15 million years ago, giving rise to the Columbia Plateau in the PNW - but obviously, that didn't lead to a mass extinction event.

Dinosaurs: go extinct
Cody: *plays reverse card*
Throughout the whole Paleozoic era, trilobites continuously thrived starting from the Cambrian era. It would be interesting to see modern trilobites today.
Their diversity was severely depleted by the Permian though. Doubt they would have survived multiple marine extinction events during the Mesozoic.
@@Ozraptor4 The great dying never happened in this scenario though, trilobites likely would have the necessary diversity to survive in this case.
@@Arthanias Trilobites were on their last legs *before* the Great Dying began. They never fully recovered after the Ordovician extinction and took major hits in the Devonian. By the time when the latest Permian, the global diversity of trilobites had been reduced to a single order of 5 genera, down from 10 orders and 1000s of genera during the Ordovician.
Remember, without the Great Dying all the Permian marine chelicerates and crustaceans that went extinct would survive as well and these were likely already outcompeting the trilobites in most niches by that point.
Horseshoe crabs are their closest living relatives.
@@Arthanias Nope.The last few Proetid Trillobite species by the end of the Permian were simply struggling too much,their diversity has been steadily dropping before that even while no mass extinctions were happening,likely due to the takeover of the Crustaceans.

There were very big mammals. Indricotheres and some Mammoth and Elephant species could easily reach the size of a medium sized Sauropod, 4+ metres and several tons in weight. However those Mammals tended to have long gestation periods which made them particularly vulnerable to environmental changes.
You know that Cody is running out of ideas when he revisits his old ones.
I know, this is like so 65 million years ago
Or maybe it was because he wanted to fix the issues of the old one with more knowledge. His previous video was full of misinformation.
It's not the same topic though. I mean it's all dinosaur focused but not quite the same topic
Good to see some coverage on this time period
I think archosaurs would still have a larger role in the alternate timeline. In particular pterosaurs. Diapsids are more suited to flight as they have lighter body plans. I still think there would have been pterosaur-like flying reptiles.
Archosaurs like protosuchus were also well on the way to filling their niches.
The most interesting thing would be how the ocean develops; wether a terrestrial species moves back into the ocean and becomes dominant, or perhaps placoderms stay king.
@@Arthanias Placoderms (other than those that evolved into bony or cartilaginous fish) were killed off in the Late Devonian Mass Extinction, which happened BEFORE the Great Dying.
So basically synapsids ruled the land, while archosaurs rule the seas and the sky.
What a sight that would be

"Hey look another primate body type right before the greatest mass extinction event in history"
Wait,

I wonder if the primate body type is the tendency for evolution, and if it is so, if big brains are basically a inevitable product of it. That would mean intelligent alien life could always be mostly humanoid.

Something interesting you should look into is what would today be like if Titanic never sank. There's actually a lot that changed because of Titanic, like mass communication with the telegraph got crazy popular because of it and without that we probably wouldn't have gotten things like radio and TV and the internet. There were tons of influential people on the Titanic as well. And there's also the regulations of ships that went into effect because of Titanic and the founding of the ice patrol. If you *really* wanna dig into it there's some very small chances of things like air planes never getting popular for travel, gigantic and fast ocean liners, and the tiniest possibility of the world wars not happening. (VERY TINY THOUGH!)

There are two more options, which I think should be explored in a future video: The possibility that humans evolved again but laying eggs instead of giving birth, and the possibility that the mammal with opposable thumbs would evolve enough to survive the extinction event by literally eating (processed) trees and having greenhouses with concentrated sunlight. The carbon dust from the fire keeping the cavern-system and greenhouses warm would also help the plants in the greenhouse grow faster, textile air filters would be used to keep the volcanic ash from being breathen in by the scavengers and woodcutters, and the dried-up megafauna would make for great firewood once sawed in manageable pieces. Technological groups would have an edge in surviving, which would make them evolve even more towards technology, which could lead to that version of humans to be a lot more active in populating and repopulating the Earth after the asteroid.
