Quote:

Eventually, over many generations, the pigmentation of those Indian will change to allow for the greatest useage of the sun on the skin.

This would only work if the people who got rickets died off before reproducing. Its not the need to survive that drives the change, its the luck of the draw in genetic mutation that allows a species to survive.
