[QUOTE]Originally posted by Narmerthoth: [QB] [QUOTE]Originally posted by Tukuler: So far a lot of tooth gnashing and hand wringing but not even one attempt at falsifying any full paragraph context Finch proposal. [b]This means no one has found any part of Finch's Vitamin D - albinism hypothesis on the evolution of white skin in Europe to be unsound.[/b] There is only dislike for Finch's hypothesis. Here it is again with the same invitation for any and all to pick one or all of its premises, quote such premise(s) in full paragraph context, and then disconfirm. [IMG]http://img109.imageshack.us/img109/1627/finch1985caucasoidevolu.png[/IMG] [/QUOTE]I regards to the embolden question above, the hypothesis is absurd when you consist the dynamic range of wavelengths in which Eumelanin captures solar radiation compared to white skin which becomes a narrowband filter to available solar energy capture. [IMG]http://i32.photobucket.com/albums/d25/GoldenMenes/EM-Waves.png[/IMG] Black/Brown Eumelanin is comprised of all of the wavelengths of the E-M spectrum and therefore can absorb energy from all of these sources, in Africa or Europe. If you de-pigment to white (actually red/pink), then you narrow the available wavelength to just within the red/yellow spectrum within visible light band, or approx. 600-700nm. So, essentially you go from having the ability to absorb ALL from Gamma to Radio to just a little fraction of the band within the visible spectrum within the lowest energy bandwidth. It doesn't take a math degree to see which melanin type absorbs the most energy in any environment. What the proponents of this theory also neglect to state is for every action, there is a reaction. A reaction typical in whites who have lost large percentages of Eumelanin is, a greatly lowered immunity system. Not only is the available energy resource band limited, but the body also becomes susceptible to radiation damage from all other wavelengths outside of the Yellow/red wavelength. Hence, the need for limited direct sunlight exposure and toxic sunscreeen. So, what the theory suggests is that nature depigmented whites at the expense of their immunity systems. I don't know about you, but I really don't believe that natural selection works so haphazardly. Albinism byway of TYR/P-Gene mutation must have originated in Africa and the original migrants into Asia & Europe most certainly were comprised of waves of African Albinos. [/QB][/QUOTE]
