[QUOTE]Originally posted by rasol: [QB] [QUOTE]This is based on Jablonski's theory that skin color can change within 500-1000 years if vitamin D is absent.[/QUOTE]Can, yes, but she does not conclude that it *must*. This is simply a calculous based upon the amount of time it would take a highly postive selected for trait to sweep thru a small population. It is not at all clear that leucoderma is *always* that highly selected for, which is why only Europeans have lost enough skin color that the ethnonym 'white' is appended to them. However virtually all sub-tropical to arctic northern populations have lost their original black skin color. Unless you are saying that Eskimo are Black? One of the points of the article is that NorthEast Asians lost their original dark skin independantly, due to the same environmental cause, and hense have unique indigenous mutations on skin color receptors: [i][Mutation] SLC425 [b]causes paleness[/b] in Europeans, but not in Asians.[/i] This is powerful proof of convergent evolution due to environmental selection. Did you not read this, or do you simply not understand it? [/QB][/QUOTE]
