Nigger pavement apes' shitty dark bodies are no more due to any "adaptations to solar heat" than their monstrous nostrils or coarse velcro "hair" are. Carleton Coon was just an ignorant Darwinist fool who, like all 20th-century Darwinian fools, believed humans and niggers are both apes and are "descended from common ancestors". (Hence the Darwinist libtards constant, deliberate, and degrading use of the exceedingly misleading words "white" and "black" to describe mankind and niggerkind respectively)

The tawny Hottentots live side by side with sable Kaffirs in Africa. The ancient "Indians" of California, in the latitude of 42 degrees, were as "blagg" as the niggers of Guinea. And in Africa, the darkest niggers are 12 or 15 degree north latitude; while they become less dark the nearer they approach the equator. Dark eskimos live in the exact same latitude as the fair humans of Highland Scotland, yet they don't have similar fair complexions. Gorillas and orangutan apes who live in rainforests of Africa and Asia, away from the "intense" solar heat", have similar shitty dark bodies as the full-blooded groids of sub-saharan Africa. Here in Australia, far away from the equator, the so-called "aboriginal" niggers have the same distinctive shitty dark bodies of the niggers of Africa. As you can see, Darwinian hypothesis of "natural adaptation" is nothing but a demoralising delusion wherewith libtards try to degrade mankind to social "equality" with disgusting Apefricoon beasts.

(PS. it's a well-known scientific fact that black objects absorb the most heat. And this is why you hear scientists telling elderly and young children not to wear dark clothes during scorching summer days)
