Default Serious question about white people and evolution.?



When a blue eyed white person and a brown eyed white person have childre, they can produce children wither either brown eyes or blue eyes. Even if all their children are brown, and all their children's children are brown, the blue eyes can still resurface and be expressed in their children because the gene for blue eyes is still passed down.

Well, why isn't that true for white people and dark skin? All humans are supposed to have originated from apes, and we all had dark skin. Somewhere along the line, white people deviated from that line and had a mutation that made them have white skin.

The question is, why aren't the genes for dark skin ever resurfaced in white people, the way that the blue eyed gene resurfaces in a family of brown eyed people? It's unheard of for two white people to produce "a black child."

What gives?

Unlike eye color, skin color isn't given just by one gene. I'm not sure, but I believe that is a set of genes which determines which color your skin is.

Black color in white people, or viceversa, can reappear, but this usually does by jumping a generation (like to grandparents to their grandchildren). I don't know how many generations it can "jump", but as it goes further it is more and more difficult for them to reappear.

The dark skin gene in white people is in recessive stage so that's why they never express as white skin gene are always dominating on them.
