Human evolution and fur

[pgrimes15]

So I was watching Ancient Aliens (I know, I know) and the dude with crazy hair brought up a good point. Why did we evolve to be furless just to have to kill animals and wear their furs to survive the cold in ancient times? Anyone have a good reason for this?

According to an article in New Scientist No. 2857, the most popular theory currently is that when human ancestors needed to venture out into the savannahs that were developing when Africa experienced climate change (became hotter and dryer) , selection favoured individuals with less hair that could shed heat through sweating. This is much harder to do with a thick fur, so this evolved out of us. An interesting point is that other plains dwelling creatures were not furless, but needed to keep it to deal with the cold nights. Mark Pagel at the University of Reading UK argues that our ancestors could not have shed their pelts until they were smart enough to deal with the consequences (i.e. make fire, shelter, clothing), which was probably after modern humans appeared approx. 200,000 years ago.
The article points out 2 other facts that confuse the issue. Pubic lice evolved around 3.3 million years ago, and they could not have done so until human ancestors lost their fur, thus creating the the louses' niche, - and body lice which live in clothing evolved around 70,000 years ago.
As ever with science, the evidence is not conclusive but merely points to certain deductions that may be adjusted as more things come to light - exactly the opposite of religion which has its' conclusions (the bible) and retro-fits the evidence to it.
