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.
Thank you to Julio Lacerda ( JulioTheArtist) for the excellent Australopithecus and persistence hunting Homo erectus illustrations!

The Descent of Woman, by Elaine Morgan, is the finest theory I've ever read concerning this. The theory posited here doesn't explain the hyman, uniquely found among aquatic species. Same hold for the shape of our nose when other apes, save one, have forward vents. The apes with noses like ours, swims, too.

So at what point was it determined that homo species could survive without fur? If it was necessary for our ape-like ancestors to have fur to keep them warm at night, I'm assuming at some point that was no longer an issue. Did the climate change, or was it connected to our growing brains which were gradually giving us the ability to make fire and fashion clothing?

You can use cricket for example. Try pick male female cricket and wait till it mate and lay an egg After that try kill the biggest one and give the other less food over week See how the size was changed over generation and you got micro evolution there. You act like apex predator to control population of the cricket while the cricket is actually trying to survive so it change size and more adapted to less food

Evolve to what? Human? Other species can't and impossible for evolving to another already excited species Also that needs million years of time.

There's a theory that humans had a phase in evolution when we evolved along a shallow coastline, eating fish and crustaceans. It's called the aquatic ape theory. It might explain why we are having large brain capacity thanks to the eating habits, being bipedal and also why we have lost our fur.

Really appreciate having this more or less answered. So much for all the zany hypothesis in that Naked Ape book from the 60s, such as that we went from the trees to the shoreline and our hairlessness helped in our ability to swim.

How far has humanity come when a totally natural thing as sweating is described as gross???? Let’s face it, we humans drink and eat so we do number one and two! And since we are warm blooded we have to get rid of some heat and so we sweat! All natural!! On the other hand it should be fun if we panted instead in this day of mobile phones. Just imagine all those calls with heavy breathing....😂😂😂

Ugh. Humans pant during exercises just like other animals, but panting doesn’t make us cooler. Instead we also have to sweat in addition to feeling like your chest will rip open with panting for no helpful reason. Just one uncomfortable feeling at a time please.

@John Thumble theory in science means hipotesis that came from fact. Also we don't evolve from apes or even monkey, but we're classified as apes in taxanomy Human apes and monkey are came from same common ancestors

@Larry Foster You know all of science is composed of theories right? You can't get higher than a theory. The common definition of theory is different from the academic one. Also none of this changes the fact that we are apes and are composed of the same kind of cellular machinery all life is. It wouldn't make any sense if we weren't related.
