One thing is appearent, most people equate caucasoid with blonde hair, that is most incorrect.
Caucasoid skeletal morphology has nothing to do with hair color, in fact most caucasians, DO NOT HAVE BLONDE HAIR. Also people equate caucasians with
Europeans, that is not the case at all. Caucasoid is a very distinct type of skeletal and dental morphology and has nothing to do with hair and or
Blonde hair is rare, even in European populations, and can be traced to a small ,very recent Eurasian imigrants into northern Europe, 3-5k years
Red hair has been linked to Homo Heidlbergensis and neanderthals, it predates modern humans by several hundred thousand years.
It's my opinion that blonde and red hair in modern humans can be traced to an indiginous new world population that has been replaced by various waves
of people from northeast Asia, whom just happen to be their descendants.
It is likely that "white skin" evolved in a central Eurasian population in response to diminished levels of sun light after the Toba eruption. This
is an evolutionary adaptation to make more vitamin D.
Or my own theory is that an already lighter skinned people spent several generations in a low light area, such as an area that perpetually shrouded
in dense fog, such as the central valley of California.
During the last ice age, the waterlogged san Joaquin valley would have been one of the foggiest places on earth.
Today here, with a wet winter the fog sets in and there have been times where you could not see the sun from the middle of November to the first days
of February, literally two months where the best you get a dull glowing orb through the mists.
Even the local native Americans' mythology reflects the lack of sunlight in tales about coyote stealing the sun from or for the valley or mountain
