What Caused the Pleistocene Extinctions?
The Pleistocene was known for having a variety of large-bodied animals throughout the world. All of a sudden, they disappeared. Today, we'll investigate the potential causes behind the extinctions.

There are only 150 mouse tailed bats, it’s so sad how most animals here are endangered but a lot I didn’t know about, and one more person = one more conversation effort. And the more who know the more can help. So please anyone who sees this Google some guys mentioned in the video learn and spread awareness!❤ we can protect them together’:D
Tree kangaroos?! Aww
love your narration - American in the most charming, elegant, and pleasant way!
Good video
True
My beliefs here is that the quickly changing climate was not only distressing the Fauna but the early modern Humans were forced to migrate long distances in Bad Weather to obtain the meat necessary for survival, of course they affected the animal population but because the wildlife was struggling it helped with their extinction where otherwise it may not have. I would like to know what was going on in Africa, etc. Since South America also lost all it's Mega-Fauna you can't say the lack of tropical temps. was the cause (South America was still geologically very close to Africa).
The information is good but you need better video editing software my guy wouldn’t hurt to organize this properly maybe into PowerPoint slides or a nice graphic would be nice. Peace ✌️
Mammals: the only group of animals that are capable of doing what the Dinosaurs before them once did.
Animals & insects did not evolve God almighty created all the dinosaurs & extinct animals ever known ; Genesis 1:25 & God made the beast of the earth after his kind & cattle after their kind & every thing that creepeth upon the earth after his kind: & God saw that it was good.

6:08 Lmaoo you know what good to actually hear you rant and show your personality more in I this video for the first time !! It really makes you stand out I appreciate the uploads 🔥💯
Is Ozil I will be playing with them all day and guess what I'll be teaching him how to walk
This one very much is on humans, climate flat-our doesn’t work due to the fact these were animals that survived numerous warm intervals during the Pleistocene and with many actually being better-adapted for the warmer, more forest habitats associated with warmer climates like those today.
2:12: caseoh
Garbage.
against your religious garbage
What about the Dinocrocuta?
Never stop these videos please. They really are the unique part of CZcams only one person is doing. Looking forward to seeing evolution of humans, minks( wolverines/weasels), and birds

Proof?
26:30 Can you tell me what is the difference berween chinchilla and chinchilla rats?
2 different families of rodents
11:03 Like the folks over at the Pleistocene subreddit. They treat the overkill hypothesis like it’s gospel.
Our ancestors? At that time white people didn't exist. Lmao. Hmmm.
Of course humans set fire to Australia if the spiders now scare you imagine back then...fire was the only logical choice
These animals ate people. They were fighting for their' lives, man overcoming nature was never guaranteed. These weren't just cute harmless domesticated animals. They weren't the victims, they were just instinctual creatures, a danger to society. It was never guaranteed we would survive and not be the ones to go extinct, only primative tools and cooperation gave early man the slight advantage. Our' other primate cousins didn't survive and went extinct, they were less creative and didnt communicate as much but our'dominance was never guaranteed and humanity could have been extinquished then. We were the only ones because people were hunted by these animals, they had to take them out
Essentially, we killed them off on purpose and forgot but it was likely by design, the hunter gatherers intended to make land they could keep and not flee from so they planned ahead that's what set the human race apart if we hadn't come together to drive off the animals that were eaters of man then we could never have a truly stable society without first conquering nature first it's impossible so they eliminated the most dangerous animals for the sake of the less able. There is also the story of the great flood and likely many large-scale shifts on the earth due to the climatic differences at the end of the ice age and the piles of glaciers it freed up as well became an issue
👍⭐⭐⭐⭐⭐Finally a video about this. Great video!! many thanks for making such a great content!!❤❤
I'm wondering why deer made it through the pleistocene extinctions very well
3:02 subway surfers is the most the random part of this video
Your saying the skulls of these reptiles show similarity to mammals, similar but not exactly the same. The big problem is mammal means 'mammary"gland that produce milk, Reptiles do not have glands that produce milk, nor did this evolve from sweat glands, as Reptiles haven't got that either.
and?
You lost me when you said Pakistan was west of Africa. While you could go west to get to Pakistan I'm pretty sure the ancestral proboscideans went east. You also seemed shocked that both female and male African elephants had trunks. Pretty sure you meant tusks, but your sloppiness makes me not want to watch your videos any more.
Long ago the world used to have a lot of megafauna but everything changed when humans attacked
MMMONKE
RAT TO MONKE
I don't buy into the human Extinction theory for megafauna the math just doesn't work for me, like the theory Earth's water was brought to the planet by asteroids and comets, again the math doesn't work..
Concerning the end of the video. Firstly, in terms of archaeology the number of human burials in late Pleistocene North America is severely lacking, even during the Clovis period, and especially compared to Afro-Eurasia. As such I do not consider a lack of kill sites to be proof of anything. Secondly, the end of the penultimate glacial period did featured turnover, but it did not have a widespread, comprehensive and regionally biased extinction event amongst taxa of large animals and only large animals. And that’s notable because the transition between the Eemian and penultimate glacial period was pretty dramatic. Lastly, there is no reason why animals which are naive from being on islands should be so different from animals which are naive from being on a different continent.
Africa's Pleistocene ecosystem/megafauna remaining almost completely intact, non-African megafauna cohabitating with Humans successfully for thousands of years, the low number/density Human population & clear evidence of the conversion of Mammoth Steppe to Tundra + Boreal Forest are all clear factors that makes an anthropogenic origin for Pleistocene extinctions utterly ridiculous. People need to stop letting decades-old confirmation bias cloud their thinking.
I can't believe i watched this video twice and both times looked over at exactly 31:01
quite good - they mix palaeomerycids with dromomericids and other mixes too but in general OK
a dog domestication video.. yes
love this chanel many thanks for making such a great content
i hated the volume increase at 13:33 jesus dude can you calm down how annoying
Humans caused the extinctions. The climate change hypothesis makes no sense because a) many of the species that went extinct survived countless ice ages and interglacials with little issue until humans came into the pictures. b) If climate main was the main culprit, how come species that were supposed to benefit from climate change died off as well? Many of the temperate forests in which mastodon lived and fed now cover a big percentage of eastern North America and yet we didn't see a mastodon population rebound. Quite the opposite, we see them dying out just like the mammoth.
That also raises the question though of if it was humans who caused the extinctions, at least in the Old World, why didn't they wipe out the mega fauna tens of thousands of years ago when many of them died out roughly ten thousand years ago?
@@Spongebrain97 Because extinction isn't always a sudden occurence but rather a gradual event. We might think of a few thousand years as being a long time but from an evolutionary a whole species going extinct in just 5,000 years or even 10,000 years is extremely fast. Evolution operates on completely different time scales than humans do. Remember that those megafauna species weren't used to having predators at all. So all it took was a slow but consistent hunting pressure over thousands of years for them eventually to go extinct.
@@guerreiro943Another point to add, is that the severity of those extinctions have a correlation to the contact the continent has to Africa, since the place where humans originated still retains many megafaunal species (who were more accustomed to hominids), while Oceania and the Americas suffered dramatically. Furthermore, the oceans didn’t experience significant change in biodiversity during the Pleistocene, despite the changing climate (being the last extinctions far before with the joining of the Americas between the Miocene and Pliocene changing oceanic currents)
What about how climate change shrunk the megafuna it's a theory
Rubbish! Mammals produce milk to feed the newborns. I give you 10 kg of grass and give me 1 litter of milk which composition is perfectly balanced with vitamins and nutrients and which has no smell or taste of grass or blood which carries it to the tits. Look for a creator and ask for guidance.
no, that's you completely ignoring biochemistry because of your pathetic religious superstitions
The Diamond and Pearl snow route song is so fitting❤
The thumbnail feels nostalgia
Never ''Evolved'' they are different species of Elephants ,there's no fossil record that proves they ''evolved'
Here in Australia, there hasn't been any evidence of Aborigines hunting the megafauna. However, what there is evidence of is that the fire-stick farming they use caused a number of plant species to go extinct. Tests on the shells of Geniornus and emus from that era show that emus had a very generalized diet, whereas the Geniornus relied on a few specific plants, all of which went extinct around the same time as the megafauna.
Ridiculous
