EVOLUTION OF SKIN COLOR IN HUMANS :-
Skin pigmentation is the product of two clines produced by natural selection to adjust levels of constitutive pigmentation to levels of UV radiation. Photolysis of folate and its main serum form of 5-methylhydrofolate is caused by UVR and by reactive oxygen species generated by UVA.it is primarily to regulate the amount of ultraviolet radiation penetrating the skin controlling its biochemical effectslability and Melanin pigmentation is adaptive and it is maintained by natural selection because of its evolutionary lability.

Questino 7. How I genetic drift different from natural selection? A. Natural Selection occurs because some alleles confer higher fitness, whereas genetic drift occurs because of sampling error. B. Natural selection has a stronger effect in large population, whereas genetic drift acts primarily in small populations. C. Natural selection is a mechanism of evoltion, whereas genetic drift is not a mechnaism but an outcome of evolution. D. Natrual selection tends to cause very rapid evolution whereas gentic drift tends to...
