How Humans Lost Their Fur

↓ More info below ↓
We’re the only primate without a coat of thick fur. It turns out that this small change in our appearance has had huge consequences for our ability to regulate our body temperature, and ultimately, it helped shape the evolution of our entire lineage.

Human persistent hunting is literally the stuff nightmares. tall thin creatures slowly chasing you forever until you die. you can outrun them for now, but they’re still coming and there’s nothing you can do to stop them.

[Rubrickety]

When do paleoanthropologists think Homo Erectus first evolved the ability to conceal its genitalia via clever camera angles and obstructing props?

[ManicPandaz]

You know when you look at a sphinx cat and say, “oh my god what happened to that cat?!?”, that’s what other apes think when they look at us.

[IncriminatedAntelope]

A man who lived with a tribe in the Amazon or something, said they ran for 5 hours and the tribe only stopped for a handful of muddy water, then kept running. Literal machines & all extremely physically fit

[choobooloo]

That is some very strategic gazelle ear placement.

Having once had the experience of being unable to sweat for a period of several months, I can say with certainty that sweating is a deeply underrated human ability. You may think sweating is gross or inconvenient, but it's a whole lot better than not sweating!

[Avintrue]

Jane Goodall also suggested that we spent time in water, another way to cool down, which also caused most other mammals to go hairless. As it happens, prime apes today will always walk bipedally in water which could point to how we began to walk bipedally more often as well.

Me looking at my belly: They know nothing, my friend.

[GregoryTheGrster]

One very critical aspect of having hairless skin is that you then can have tattoos, which are important for coolness (though not thermal coolness).

10:57 "having hair on our heads …"

I probably come to this realization after every Eons video, but it’s simply stunning how much we know about life, history, and our planet. So much of this was unknown just a few decades - and definitely a few centuries - ago. We have come to know so much, the last remaining questions are things like, where did the entire cosmos come from. And in a sense we do have decent, if incomplete, answers at that.

And now I’m absorbing an overview of a few million years of evolution on my handheld supercomputer in my climate controlled bedroom. The power of science to enlighten and improve the human way of life is without compare.

I'm not going bald, I'm evolving.

[sboneliberator]

bruh just imagine being an animal and being like "phew I lost those humans" and then you just see an army of screaming monkeys with spears charging at you.

[Alias_Anybody]

"What did 500 million years of evolution lead to?"

"Naked sweaty men"

[workmix]

Major props for clarifying your use of the word “we“ I wish more people would. The most carelessly bandied-about word in the English language— in any language.

[anjap]

As an Australian entering summer, I sure am glad I have 2-5 million sweat glands right now. My clothes might beg to differ though

[susyshepard]

I was a nurse for almost 40 years. I've seen a lot of naked people and I've got to tell you some people still have " fur".

[mohsinish]

3:24 "This has made a lot of people very angry and has been widely regarded as a bad move"

This is one of my favorite Eons episodes. All of the human evolution ones are. I've always thought: we're such a unique mammal! We're the only mammal that stands on two legs, the only mammal without fur, blubber, or any other thick insulative substance, and so on. These videos explain them in a clear and concise(as well as fun) way, and I love them!

Persistence hunting is now called a 9 to 5. That’s how humans lose their souls.
