It's also fascinating how the strongest apex predators are the least likely to survive extinction events, since they are always the most vulnerable to any collapse in the food chain. Smaller animals appear to be way more adaptable while the strongest almost never survive.

[@rodneywhitley1323]

I think it's omnivores vs. Herbivores or carnivores.

[@WVa007]

Everyone saying they’re unsubscribing from an educational channel because he expressed his opinion are the same ones who call people snowflakes. Grow up. Get over it.

[@gordo1163]

God forbid people have different opinions!

[@miami444]

I mean if you claim to be an educational channel you can't openly be a biden boy and expect people to not unsubscribe. Ima still watch cuz i do what i want but those comments shouldn't shock you.

[@nicksweeney5176]

You need to grow up and get over yourself. He's just devalued himself and discredited himself; he's so degraded himself as to serve as pitch boy for a corrupt regime.

[@Siatsgaming]

Simple, leave politics out of education

[@staticshock8361]

I will still watch because I love the content, but there is no need to bring political opinion in an educational documentary.

[@ktkalicka]

Really cool compilation, such fascinating facts and worlds. Paints a good picture of prehistoric life.

[@wildcatrewind]

Just bc you are talking about the time period that Biden grew up in doesn't mean you have to mention him 😉

In the middle of Pangaea, rain was scattered.

[@mrdavman13]

Yep vast deserts actually sprang up because of the lack of established terrestrial plants as well as low amounts of water in the area due to the huge amount of area between the ocean and middle of the super continent. Eventually it balanced out more tho but it definitely created all sorts of weird climatological effects.

[@indigolarsen3191]

I realise that adding captions to long videos/documentaries like this would be time consuming, but autogenerated is incredibly hard to follow along with given the inaccuracies and lack of punctuation. I’m assuming this channel could afford doing that, and that it would be greatly appreciated by deaf and hard of hearing folks (I am neither). And personally I would just love to be able to see the scientific terms spelled out, so I can do further research afterwards. I hope you would consider this, Anyways, I’m only 8 minutes into the video so far and enjoying it immensely, so thank you!😊

The Iceage started about 2.4 ml years ago and lasted to about 11500 years ago. So, the iceage ended about 11500 year ago and not 300 ml years ago.

[@WhiskeyToro]

Children of the future watching this and if you ever come across my comment--please know that this is all just hypothetical. We will NEVER know what the past was like millions and even billions of years ago. There's literally no way we could ever know. This is all regurgitated information that is from people that have been entrusted as the smartest people in the world...just like we don't know how old the Earth actually is. But it's fun, not fact. One day, human life will cease to exist on this planet-- that is an absolute certainty. What follows... who knows? And that's what makes it all so fascinating

HOT!! Way more humidity. Oxygen was up to the 36% marks. We humans would’ve been miserable, if not dead!!

[@prototropo]

The ancestors of mammals were never "reptile-like!" That is an old, discredited idea. From our very beginning, we were distinct from reptiles--because both lineages evolved from amniotes, which had descended from amphibians, and their new their amnion allowing their eggs to survive away from water. It was shortly afterward that amniota itself branched into two lines--synapsids--our oldest ancestors, and sauropsids--the family that produced lizards, snakes, crocodiles, dinosaurs and birds. Both diverged from amniota, snd so we were no more like reptiles than reptiles were mammal-like.
