I’m not quite sure if I am wording this question correctly, but I am wondering what skin color would the original homo sapiens. Are humans naturally light skinned and only darker skinned owing to the sun or vice versa owing to some sort of vitamin deficiency. Perhaps there is no answer to this, but i am curious to hear what people think.
And please, do not let this question become some wierd race war. Thanks in advance.
This Wikipedia article gives a reasonable summary of thinking on the issue.
Gorillas and chimps are light-skinned beneath their hair. The ancestral human probably was also.
Upon evolutionarily losing their hair, humans probably first developed dark skin in order to protect against destruction of the B-vitamin folate and skin damage by intense tropical sunlight. Development of lighter skin when some populations migrated to areas with less intense sunlight probably has to do with manufacturing enough vitamin D in the skin.
After doing some checking around, I’ll withdraw gorilla (my mention of it was based in part on the Wiki article). However, I’ll stand by chimpanzee, at least in the case of young animals (older ones may darken). In any case, chimps are more closely related to humans than gorillas are.
It has something to do with chromosomes and can vary from albino white to ‘blue’ black, depending on the combination, with something like sixteen distinct ‘colors’ IIRC. Perhaps an expert can elaborate.
BTW No one has any idea what the ‘original homo sapiens’ looked like, but lots of conjectures.
As I pointed out here, they are no expert. Man’s natural skin color is the average skin color for the human race. In that case, average would not be so bad.
It says “sexual preference,” implying that human males may have some innate preference for lighter skinned females independent of other selective factors. (A similar preference on the part of females could be postulated for facial hair in males. On the other hand, I have seen speculation that facial hair in males could have been selected for by intermale competion, by favoring those that were better able to conceal their emotions in aggressive interactions - the moustache and beard concealing emotional expression by the mouth.)
An innate male preference for light females exclusive of other factors seems unlikely to me. However, if lighter-skinned females are more likely to have healthy babies due to a better ability to utilize calcium, a preference by males could develop for this indirect indicator of fecundity. However, all this is speculation - I am not aware of any evidence for this.
