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.

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

    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).

    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.

    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

  • @entity_unknown_
    @entity_unknown_ Před 11 dny

    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

    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.

  • @alexanderstone9463
    @alexanderstone9463 Před 13 dny

    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.

  • @bustavonnutz
    @bustavonnutz Před 13 dny

    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.

    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.

    • @Spongebrain97
      @Spongebrain97 Před 14 dny

      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?

    • @guerreiro943
      @guerreiro943 Před 14 dny

      @@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.

    • @piporindo5788
      @piporindo5788 Před 10 dny

      @@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)

    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.
