First of all, Europe's glacial refuges were much smaller. Compare the landmass of Iberia, Italy and the Southern Balkans plus Anatolia and the Caucasus (Western Palearctic, belongs to the European biogeogrphical region) to Southern China, India and South-East Asia. Plus Iberia, Italy and the Balkans would have all been isolated due to glacial ice sheets in the Pyrenees, Alps and the Dinaric mountains. Smaller refuges means smaller population sizes, smaller population sizes means increased vulnerbility to e.g. human hunting. And then even in South Asia with its extensive habitat for megafauna Stegodon (a browsing proboscid), Plaeoloxodon namadicus (a huge elephant), Palaeoloxodon naumanni (Japanese elephant), a giant tapir, several water buffalos, Hexaprotodon (basically a hippo) and more went extinct.

Avoiding humans seems to be a fairly good survival strategy.

As Nero Bernardino said, the ozone layer is usually in some kind of equilibrium. Whatever dissipates or vanishes through natural processes, gets also replenished through natural processes. We disrupted this equilibrium with the large-scale production and release of chlorofluorocarbons (hydrocarbons with chlorine and/or fluorine atoms) into the atmosphere. They were used as aerosols (i.e. the gases in spraying cans etc.), in refrigerating, and as solvents. These chemicals also react with ozone in the upper atmosphere and bind the ozone, thereby depleting the ozone layer. Starting in the late 70s, and esp. with the Montreal Protocol in 1987, the countries of the world agreed to severely reduce the use of chlorofluorocarbons, and today, we nearly stopped using them. Therefore, the ozone layer started to return to its normal state, slowly closing the gap.

This Ice Age series was amazing!!! Everyone should see these videos. It gives a great understanding of how the balance in our atmosphere is very delicate and how small changes make a big difference over a long time. It can also help understand how a big change over a small time can have large effects that are difficult, and most likely impossible, to reverse. Climate change and loss of biodiversity will surely have massive effects and someone might even be able to make a video like this in just 100 years looking back at how insanely different the world was in just 1800.

They were not very destructive though. On a big scale invention of oxygenic photosynthesis increased organic matter production many times compared with earlier chemosynthesis and anoxygenic photosynthesis. Biodiversity and amount of matter and energy available to biosphere as a result increased. Also, oxygenation of atmosphere happened very slowly, over the millions of years, and microorganisms can reproduce and evolve really fast, so I doubt many huge taxa died out, there were probably more than enough species in every big taxon to either adapt to oxygen, or find anaerobic niche. Most bacterial and archeal phyla diverged before the oxygenation, and they (many many of them we still see today) still survived. If most phyla died out during oxygenation, we would see "bottleneck" - only few phyla diverging before oxygenation, and most diverging after it from only few taxa, which survived the event

It likely wasn't. The reality is that the areas with the least decline in megafauna are the areas where the climate changed the least, and the areas where the climate changed the most suffered the greatest losses. South America's vast taiga plains turned into a rainforest, Eurasia and North America radically rearranged there biospheres as the vast sheets of ice retreated. Even when we look at Australia, likely half of the forested area of the ancient continent is under water today. In contrast, Africa's deserts are still in basically the same places, Indomalasia's rainforests are still in basically the same places (except where we've chopped them down). Grasslands & forests have shrunk or grown, but are still in basically the same places.

To have the audacity to claim that all this has nothing to do with man, a notorious extinctionist whose destructive impact on nature is known, acknowledged, documented and undisputed, to say that it was a natural event that wiped out the megafauna with stunning precision, while leaving a number of smaller species that would have been equally affected by the changing times virtually untouched, is indeed mysterious and beyond my understanding.

Love your mini documentary films bro. Please do more. This is, by far, my favorite channel.

This was awesome! It's EXACTLY what I've always wanted.

When you mentioned the destruction of the habitats of, say, mammoths, I'd say that explains extinction of large species better than human predation. Humans did expand throughout the planet together with the changing climate, and what large animals also have in common is that it takes them longer to adapt to changing climate because they usually have longer lifespans

That would explain the event if the Weichselian transition (the last major climate change that ended the last Ice Age and started the current Holocene) was a one-off event. Unfortunately this is far from reality. During the whole Quaternary (Pleistocene + Holocene) the earth experienced as many as 8 such climate changes, i.e. prolonged Ice Ages periodically interrupted by warm interglacial periods, yet the effects on the megafauna were negligible in that they didn't cause nearly as much interuption and didn't produce megafaunal mass extinctions. Actually, the last of these interglacials (that is to say the last before the current Holocene), the Eem interglacial roughly 130.000 years ago, was both longer and warmer than the current Holocene, yet the mammoth-steppe fauna survived throughout without trouble. Similarly, temperate faunal assemblages such as the European Palaeoloxodon-fauna (straight-tusked elephant, two Rhinocerus-species, deer etc.) respectively its ecological predecessors (southern mammoth and different rhino-species) survived throughout all glacial peaks, some of which were more pronounced than the last one that coinceded with the extinction of for instance the straight-tusked elephants, without trouble, even though they were restricted to small refuges. This is a major flaw in the climate-change argument, and I don't see it being adequately adressed by those who claim the climate did the megafauna in.

I would assume it was a situation similar to modern Inuit people where they effectively live off of any animal species (whales, bears, anything edible to be honest). This could've eventually lead to people actually discovering the lush forests and plains further south, where presumably they settled (or in the case of the Inuit, stay). But then again, that is my assumption.

Basically, as the climate warmed up the mammoth steppe slowly moved north-east towards Siberia and Alaska, the herds of mammoths, musk ox, rhinos, etc moved with the steppe and the humans followed. I read - can't quite recall where - that for a time the first humans and megafauna from Eurasia to make it into North America were actually trapped in Beringia/Alaska as the steppes had fully retreated from mainland Eurasia before the glaciers had opened up enough in Alaska for them to make their way into the rest of North America.

@@TheElizondo88 ditto. I would think that land bridge was always in flux, going from somewhat favorable steep, to inhospitable desert, and to being underwater. This is why you have the existence of Dwarf mammoths along the islands near Siberia and Alaska. Also, I read somewhere that while there were a few waves of humans that colonized the Americas, the Native Americans of today came from possibly just one core group of maybe 10,000 Ancient Beringian people that crossed over 20,000 years ago. The lineage does exists in Siberia but seperates from native Americas 17,000 years ago. Seems at some point when humans existed in the area there was a short lived "decent" land bridge, but its was probably not as lush and inviting as it may have been during that pre-human time when animals moving back and forth between the two continents. I think if the land bridge was more lush and long lasting you would have more human diversity in the Americans.

To add on to what others said, for thousands of years humans in the Americas lived basically _only_ in Alaska, as you couldn’t easily go east or south. As the ice sheets melted and retreated a “corridor” of sorts formed in between Alaska and the Cascadia region to the southeast. From there humans were able to spread rapidly across the continents. They went south from Alaska before going east.

They may not have done so at all. The easiest route might have been along the coastlines, once they developed decent kayaks or the like. They'd have lost access to the big, meaty megafauna animals such as caribou, bison, horses, and mammoth, but those are hard to kill with only spears anyway. And they'd have *gained* access to the arctic waters' abundant fish, seals, walruses, Stellar's sea cows, and maybe even whales.

In my opinion, this is why we should try and restore the ice age “mammoth steppe” biome, by restoring this habitat we can introduce animals that survived the ice age (Bison, Musk ox, wild horses) and make a habitat suitable for them again. In the far distant future we may even de-extinct mammoths or woolly rhinos and have them roaming the far north once again.
