This answer is convuluted.I,am willing to bet that the person giving their hypotheses is of European descent.

Dear, Dana,

As long as know genetic drift does not bring forth new traits, it may just by chance enhance non favorable traits, but the pale skin literally evolved from dark skin, which I believe is due to melanin deficiency. I think that somehow the melanin production was decreased due to some sort of a negative feed back. In my opinion this could have been a mutation. I know, mutations occur very rarely, but if a mutation occurred, then, as you wrote, a genetic drift occurred, the evolving of pale skin makes better sense to me.

Oculocutaneous albinism (OCA) is a rare, genetically inherited condition passed on by both parents to their offspring, resulting in a significant reduction in or absence of pigmentation in the hair, skin, and eyes at birth. Individuals with albinism are very fair-skinned and fair-haired, with (most often) blue eyes that can take on tones of purple or red in bright lighting.

But due to such lack of knowledge as to why their “white skinned” off springs came about, African mothers and fathers became more and more fearful and suspicions and began to separate their growing number of “white skinned” off springs away from the “black skinned” (pigmented) population.

Eventually most of the “white skinned” off springs of “African” mothers and fathers formed several groups and began to migrate northward through Egypt to another area of Africa which is now called Europe, seeking a more hospitable living environment and to escape the intensity of the equatorial hot climate of the great river valleys and great lakes region of Central, Eastern and Southern Africa which was then and still is South of what is now called Egypt.

The “albino” group moved up in the mountainous area during the Ice Age or Glaciations period that lasted thousands of years further isolating themselves from their original parent population in Africa. And by being in such isolated living condition for such a prolonged period they also interbred (within the existing parent groups) thereby creating additional “albino” offspring from “albino” mothers and fathers who were then and still are direct descendents of African mothers and fathers.

A mutation results in a change of the DNA sequence within a gene or chromosome of an organism resulting in the creation of a new character or trait not found in the parental type. There is blonde hair among the black Australian aborigines. That is an example of a mutation. Albinism is a good example of a mutation. The White Race has the genetic inability and absence of melanin to produce the different skin pigments seen throughout the world.(melanin means black in greek) That absence of skin pigment creates the inability to produce colors. As a result, uncolored or white skin is produced.  Recessive genes delineate body characteristics that are masked or not expressed when a contrasting dominant black or brown gene or trait is present.

White people's ancestors were black.

Black people's ancestors were apes.

Apes are Caucasian.

Apes evolved from monkeys.  Monkeys are Caucasian.

Monkeys evolved from mice.  Mice are Caucasian.

It is the default color of mammals.

Shave your cat to see.

I hope this has helped a little bit.

I can answer questions about evolutionary mechanisms and theory, including genetic drift, mutation, natural selection, etc. I also can clear up misconceptions about evolution as it's sometimes talked about by those not well-versed in the subject (e.g., some politicians and many religious fundamentalists).
