We all know that at the beginning of a summer holiday we burn quicker and easier than at the end of our holiday. This is because our skin has adapted to the heat given off by the rays of the sun. In a very small way this is for our survival. We haven’t actually changed in person at the end of our holiday, but our appearance is noticeable. So much so that people often remark on how well or tanned we look.

Now, lets say that any given white Englishman went on a permanent holiday by means of migration. It has to be assumed that the place he chose had a significantly warmer climate than Britain. After several years you would expect this man to have a much darker skin pigmentation than when he left. Also worth noting is that if you didn’t know him before his departure from England, and only after several years of being in his new habitat, that he had indeed always have been this way. Why would you not, you have nothing to base any other hypothesis on.

It appears to me, although I am not a dermatologist or in any way an expert on this subject, that the reason for this change is to adapt the skin for a constant bombardment of the higher concentrated rays of light than they where used to in England. This would seem to me so that they do not burn as quickly or as easily. I don’t think many people would disagree, except maybe an expert, who with their credentials could explain the physics behind ‘tanning’. However, I believe the resultant out come would be the same, fair haired, brilliant white people burn more quickly and easily than say a dark haired, olive skinned person.

Given that our friend from England is now olive skin, but started off a more plausible white, if I had the resources I would like to consult an expert to ascertain whether given that, if our friend had children with a female of similar history, would that child be born in the original tone of its parents, or ever so slightly more tolerant to its new environmental surroundings, olive skin? In reality, this is not important for now, as natural selection takes place over many generations and not just the mutation of one generation’s offspring. However, for the theory to seem plausible, we will assume the child was born olive skinned.

Now that this has been assumed, we have a system to base future generations on. Over many years and many generations the pigmentation of the skin will continue to darken until it reaches a tone that is tolerant to its environment. Had the skin not done this, our friend and his subsequent offspring would have burnt very rapidly in the sun of their new environment, thus making survival incredibly more difficult than if this mutation had taken place. It is then not inconceivable to think of black and white as an ancestral survival mechanism, based upon the original environment of our ancestors.

Although I do not expect this theory to change any one’s perception on racism, it merely proves a point that we, being humans, are all the same. It’s just that for the needs of the human race to survive globally, subtle mutations were required on some areas of the globe and not in others.
