The mormons tried years back to try and prove they were descendants of Israel or whatever.

huh, well that does make sense. I still think it would have helped if they had actually tested the DNA of some of the indigenous American people though.

It's not a new theory but I think there was still some debate about whether or not it was multiple waves of exodus from out of Africa or centrally basically one group. 

Looks like basically it was one group. I guess they hit the equivalent of the genetic lottery because their genes have spread and spread while everyone's elses either got stuck in Africa or died out. 

Guess you can walk a lot when you don't have TV, or internet, or anything to do and just need food, lol. 

My guess is because black people were the original people and then people evolved to have whiter skin for colder climates. Then European and Asians evolved their whiter skin slightly differently.

I think white people coming first and evolving to have black skin in hot climates makes more sense (does white skin even have any advantages for cold climates?) but then wouldn`t explain the differences between white europeans and white asians.
