Elephants are virtually bald.

M*W: Wow! I didn't realize how far back this thread went! I have studied a little about evolutionary alopecia. Yes, we have less hair now than our ancient ancestors had. I wonder if global warming has anything to do with hair loss? Personally, I think we have always been in a state of global warming, so it's nothing really new. Humans may have caused global warming to speed up with our industrialization and advanced on the polar caps, why do we need hair? Wasn't hairspray one of the causes of holes in the ozone?
Did you know that you now and the you 20 years from now are two very different people. All you share are some memories.

How high are you right now? I mean its a interesting wonderment to say the least but do you have a proposed mechanism for how global warming causes baldness?
Higher temperatures leads to higher humidity and a better microclimates for ectoparasites, which leads to an advantage of having less body hair?
Having less hair would lead to fewer parasites and thus greater fitness or reduced disease... Of course, elephants can get away with this because their large size makes them less volnerable to cold.
Hi everyone!
I have a limtied understanding of evolution and I would like to see what others think. -With all the advances in medicine and surgery to fix genetic problems will humans continue to evolve? Does evolution even apply to how human society is? I find it very hard to answer these questions because relatively humans have been on Earth for a short time and evolution takes millions of years.
I wonder if there is any difference between a child from 2000 years ago and today, if we put them in the same environment. I think the logistics are the same, only technology has changed....
Does evolution mean we increase in complexity or that we become more suitable to our environments?
I believe, and I'm not sure if it's possible, that we are not evolving, but devolving. Technology has made it possible for people with bad genes to live and pass their genes on down the road. Have you noticed that only stupid people are breeding? Anyone of average intelligence knows the world is already overpopulated. Why are you indulging yourself?! Idiot. If you go back in time, I think you'll find that you're really not more advanced than someone from 2,000 years ago. Because chances are, if you were dumb at that time, you were dead. Sure, you can say, "I can use a computer and a cell phone!" Well yes, you probably can, but you're still dumb.
Take an average person and put them in a time-machine and send them to 0 A.D. Strip them naked, and they'll die instantly. Probably by walking off a cliff or pissing off a wild animal.
We already use 100% of our brains. Evolution would not allow it to be any other way.Also, will we evolve or develope in the mind so we can use the other 90% of it or evolve it to be even more powerful?
Only if you think it should be evolution in a particular direction. And evolution doesn't have directions.so im afraid the future looks bleak for human evolution.

wait, you mean the saying that we only use 10% of our brain isn't true? If so, how so?
