[QUOTE]Originally posted by rasol: [QB] [QUOTE](Jablonski, NG and Chaplin, G, J Human Evolution 2000; 39: 57-106). Jablonski and Chaplin state: "Here we present new evidence indicating that variations in skin color are adaptive, and are related to the regulation of ultraviolet (UV) radiation penetration in the integument and its direct and indirect effects on fitness." The article concerns UV light and skin color. They also state: "In all populations for which skin reflectance data were available for males and females, females were found to be lighter skinned than males." [/QUOTE] [QUOTE]This indicates to me that testosterone is involved in skin color.[/QUOTE]^ I agree. I've written about this before. Jablonski also agrees. How does this help you? ps - You quote James Michael Howard, who claims that he 1st posted his idea to a newsgroup. What is his educational background? His simplistic hypothesis predates genetic evidence of the causes of skin color and has many obvious flaws. He runs into the problem that black females obviously do not produce more male hormone [testosterone] than non black males. He tries to resolve this by suggesting that testosterone is passed on in-utero. However, skin color can't be sustained by in utereo testosterone levels in 'female fetus' because said effect would not last after birth. Melanin must constantly be produced in order for skin to remain dark. Anyway, his hypothesis is mooted by genetic study of the actual cause of skin color in humans.... good luck trying to make a white person black by feeding them steroid [fake testosterone], it won't work because their skin color receptors are disabled. No amount of testosterone can make them black. [/QB][/QUOTE]
