the evolution of clothes?

Because man's ancestors came from the regions African plains where it was warm and nice. Once some of them started wandering into places where there were winters, it became necessary to insulate with animal skin.Now the question of why we became "ashamed" of our nakedness is a whole other issue. Perhaps EvC's sociologists could fill us on this one.

Not necessarily. Colder areas = more clothes. Warmer areas = less clothes. Here, we have the basis for educated guesses. It's a heck of a lot better than blind guesses made by YECs.

I once read a book called The Naked Ape by some guy when I was like 15. Can't remember any detail from it. All I remember about this is that the guy presented a theory on why the naked ape began to cover up his sex organ. Apparently, by walking upright, it is impossible not to show your genitals, and this was intimidating within a primitive society.

Like I said before, perhaps walking upright made it necessary to display the sex organ all the time, and to some societies this became somewhat of an intimidation.Another reason is christianity.Anyway, I grew up in Vietnam and I can assure you that it's not warm and humid all the time. Sometimes it gets unbearably cold, and I'm speaking as someone that is used to North American winters. Well, if we didn't have an evolutionary advantage such as our brain power, we would probably have stuck it up too. You are forgetting the human factor. It's like asking why aren't we going around raping every female we could find just so we could plant our seeds? Well, we can think. Well, I guess they decided to stick it up like the animal. Nothing wrong with that.Anyway, at one point, I said that the cold wasn't the only reason and that my position was nothing more than an educated guess.

Perhaps it is a combination of both protection and class struggle. Caveman A might find a better fur than caveman B and starts to say, "argg..." which translates to "haha, I'm better than you." This eventually leads to the head caveman of the clan demanding the other cavemen to give him the best furs.
