When comparing the prevalence of albinism in Africa to its prevalence in other parts of the world, such as Europe and the United States, the potential evolutionary effects of skin cancer as a selective force due to its effect on these populations may not be insignificant.[1] It would follow, then, that there would be stronger selective forces acting on albino populations in Africa than on albino populations in Europe and the US.[18] In two separate studies in Nigeria, people with albinism were found to be of reproductively significant age more often than not.
