What on Earth does that even mean?Why don't you take that advantage?
Juvenissun thinks that individuals evolve during their lifetimes.
Probably, but I've been there and seen them.
You may find it interesting to read the wiki page on dark skin. It describes how skin color is a direct adaption to the amount of UV radiation at the place of settlement, and how populations can lighten and re-darken as they move around. Here is a quote:
No, it's all due to the amount of melanin.I have not. I like to see a scientific report on that.
I suspect the cause of the dark skin are different between the two.
Actually, they come in a variety of shades. And there are other dark colored people--Australian aborigines come to mind--who are generally darker than most Africans.
Why would the amount of melanin be different?No, it's all due to the amount of melanin.
Two hundred years is only roughly between 6 and 9 generations on average, not enough to show significant changes. Human populations dispersed across the globe over tens of thousands of years.Many black Americans are still quite black even their ancestors lived in the North America for two hundred years.
It shows that a lack of general biological knowledge can seriously affect one's understanding of evolution and examples of evolution. The only solution is education, but there is often a bias against learning things that might undermine existing beliefs...This... has seriously stopped being funny. This has turned in to something horrifyingly tragic. No-one can be this dense on such a simple subject!
People with darker skin live in areas of the world where there is a higher amount of UV radiation because of large amounts of sunlight. It is that blooming simple!
As was stated in the quoted material in my post, in 100-200 generations. That's about 2000-4000 years, so it's not really feasible to verify it by direct experimentation. And the 200 years you refer to is only 10 generations at the most - way too little to make a clear difference.So you suggest black people can lighten their skin color in how many generations?
I do not believe that and like to see an actual example or experiment on that.

Obviously you are looking for some entirely different explanation. Do you have any idea what it is?Our children is poisoned by this kind of overly simplified information. We NEED to tell them that there are MUCH MORE exceptions than the presented explanation.
Why is the skin of Australians so dark? But not people in the Sahara desert?

I note that you haven't bothered to respond to my post (post 186: http://www.christianforums.com/threads/dont-like-the-implications.7973420/page-10#post-70384244), where I answered your questions concerning races of humans and why a single race doesn't evolve multiple times and/or in multiple locations independently.No. I don't think there is a good explanation to the question.
