Why didn't evolution give humans lots of body hair to keep them warm in winter?

no woman would want to shag an ape, so the hairy men would of remained single and undatable, thus their hairy genes would eventually run out.

For the majority of human existence (excepting some intermittent ice ages), our ancestors lived in Africa, and cold was not the problem it is for, say, Canadians. Anyhow, evolution doesn't "decide" what to give to which species. It tries random things and see what works best. Presumably, humans with excessive hair suffered ill effects from it and did not reproduce as often. Perhaps the hair interfered with hunting and gathering in some way or collected bacteria which led to illness. The short of it is that proto-humans with relatively little body hair had a better chance of reproducing than proto-humans with a lot of body hair.

That's a good question and I really like some of the answers you got. So, yeah I think both genders get turned off by body hair. At least now, the style is definitely against it. There is nothing pretty about hair, and yes people sweat, horses perspire. And when you are talking about eons of time, in and out of the conventional boundaries of evolution, it is hard to ignore the use of animal skin garments. They really make people look sexy.

Edit: Sorry, animals sweat, people perspire. And also, the body hair we do have is adaptive for head lice. Animals have fleas.

Remember, early humans started out in Western Africa, a very warm place. There early variations probably lost their hair little by little, and because of their intelligence, when they migrated to more northern parts of the world, they made clothing out of dead animal skins, so there would be no evolutionary advantage to those who would have been born with long hair.

hahaha well i think, when the first humans encounter winter, they don't really have that much hair so they feel cold, then they tear off the skin of the animals they hunted and made clothes to keep warm, and they felt warmth. so when they are evolving, the nature thought that, oh we don't need to grow more hair, since we have animal skin clothes to keep warm. and so the hair grew less and less and then completely were completely (well not exactly completely but you get what i mean). and then human started to think hairy people were ugly and stuff.

Humans evolved in the savanas of africa. Early humanoids did have hair but the conditions of the african savanas ment that humans had to move away from just gathering food to hunting for it. And since most of the top preditors like lions hunted at dusk an dawn, humans had to hunt during the day when it was really hot. So eventually we lost our hair to make way for sweat glands which serves as a cooling system to enable us to work hours in the hot sun. Did you know that no other animal does sweats? Humans only moved to colder places recently(40k to 100k years) so very little evolutionary changes have occured since then.

I think, According to the History, HUMANS are Formed in the Warmer Countries ( AFRICA), For Their Personal Wish, They Moved to the Coldest Countries.

Evolution does not do anything at all mindfully.

It's a constant interplay between environment and adaption. In Dawkin's book The Selfish Gene, he doesn't mean to say that we are selfish. He's saying genes are molecules being favored by their environment and how well they succeed in surviving and reproducing is what evolves us to be who we are, and who we are is...

We are successful bipedal mammals. The best on this planet. We rule. All the other mammals are at our mercy.

It is pretty much believed that humans evolved in Africa during a fairly warm period of earths history. Humans then slowly expanded to Europe and Asia, adapting to changes in climate using animal skins, etc.

I may never exactly know why...? But I am really wondering why the warmest and yet hidden body parts could grow thick and piercing irritating hair.?

And still we have to cover..!

Have a nice moment..!

It instead gave us the intelligence to find ways to stay warm in winter. If we had lots of fur we'd have a tougher time surviving in extreme heat.
