If I am white and I move to Africa and marry a white skinned person..?

Question

and my children and grandchildren only married white people... would my great great great grandkids be black?

People have claimed that the environment is the cause for skin variations. How many generations would it take, living in Africa and marrying only white people before my family line would turn black?

This is in relation to this question I posed earlier.....

Answer 1

Look at it this way--you have 8 kids, 6 are very fair skinned, several pigmented a bit darker. Due to the tropical african sun--the frequent and painful sunburns which force the fair skinned kids indoors most of the time--the darker pigmented kids are more successful--they get more crops planted-because they are able to stand the sun better. Due to the strong son--the fair skinned line is susceptiable to skin cancers--many of the generations die of skin cancer before they reach childbearing age. The darker skinned kids pass on the trait to their children. The slightly darker of the 5 childrens children again has an advantage in the tropical african day--and more of his progeny survive. Continue this for a few hundred thousand years and the people living then will be the ones whose skin coloration provides the maximum survival benefit. It's all a matter of time.

Answer 2

Based solely on what you said, never. That's not to say that your great grandkids to the 50th generation won't be darker or have greater resistance to the sun, but they'd never be "black".

You're basically taking one idea and using it to encompass everything while ignoring everything else that needs to be taken into account.

The environment *is* what is responsible but it's not the only thing responsible. Do me a favour and read up on natural selection and survival of the fittest. Maybe you'll learn a thing or two.

Answer 3

Everybody exclusively married only whites.If there were no blacks in the bloodlines there would be no blacks in your family. However, a black person can be born to white couple if there are blacks in the family even up to 5 generations back. You nor your family will"change" dramatically. You may tan easily, etc. but that's it. Dark skinned people are dark due to more pigmentation in their skin. Albino's, for example, have none.

Answer 4

it depends on the ancestry of the person you married. If the white person you married had a great grandparent that was black, but everyone else was white. And your kids married white people so on and so forth, several generations later, out could pop a black baby. Genetics are just weird like that.

Answer 5

No.

Evolution requires that a change would survive better than the original. You're not in a situation where a color change would provide better than not and then, of course, this mutation would need to happen in your family and that's unlikely too. Also, it is not only the climate that encourages change but the choices society makes. Your choice to stay white is an evolutionary choice also,

Answer 6

        The answer is, no. Skin color is mostly the result of genetics -- not environment. Environment only affects natural pigmentation to *some* degree -- not to the n-th degree. A white-skinned person has already had the black pigmentation genetic ability bred out of their genetic make-up by a thousand or more years ago.

Answer 7

Ha. They wouldn't be black in less than 200,000 years.

They would be as dark skinned as a black person within the first generation, because the body MUST compensate for the extreme exposure to the sun, by producing so much melanin that it takes many, many hours in the sun to get enough vitamin A.

(Melanin is a defense mechanism for Vitamin A overdose)

So if you moved to a village, you, yourself, would become "black," but it would be an event of evolution to be truly African.

Answer 8

I think that a persons environment has alot to do with their physical appearence, however, also in their genetic profile. Maybe they all evolved into a genetic component due to their habitat. Since most atheist seem to like evolution so well. I do believe that we were created and because of our changing habitats, we evolve and adapt to survive. We were created though. I did not come from an ape...but a human...and my appearance i got from my mother.LOL

Answer 9

I've been told that as the generations progress the color line fades and it settles into a nice shade of tan......but it's just what I've been told. Makes sense though.

Answer 10

This is ridiculous. Dark genes happen to be dominant, light genes recessive. Your family would not change races. Besides, other races than ******* have dark genes, even the Irish.
