A very small minority of people in the world demonstrate this phenotype.
Now there are plenty of other people who exist in very cold climates but do not have blond hair and blue eyes. They are "people of color".
If you are outside on a very hot day, and you are wearing Black clothing, you feel even hotter, because the color Black absorbs energy.
So the idea that skin whiteness is a result of evolutionary biology for the sake of being better able to absorb heat maketh no thenth.
Human skin has one pigment, a chemical called melanin. This pigment functions to protect the lower layers of skin from the effects of solar
radiation, it basically blocks the light. In some climates, there is a lot of direct and intense sunlight, so the skin of people in these regions
tends to have lots of melanin to protect themselves. In other regions, the sunlight is less intense, and less direct, and there are even fewer hours
of sunlight. So in these regions, a lot of melanin isn't required to protect yourself from cancer. In addition to that, the body needs
some
sunlight to get thru, because its important in the production of vitamins and the maintenance of health. In the tropics, again, there is so much
light, that a healthy amount still makes it through. In the cloudy and low intensity regions, the inhabitants have lighter colour and thus are able
to absorb a healthy amount of sunlight.
So that is why we see dark skinned people in africa, australia, even parts of south america, but paler people in tierra del fuego, canada, europe,
korea, etc.
Even within 'nations', this can be see, if you look at south indians, who are close to the equator and have high melanin concentrations, and north
indians, who are further from the equator and have lower melanin concentrations.
Why are the white peoples crawling around in caves and throwing rocks at the moon while the Black Africans are solving the extremely
complicated geometric equations in order to build The Great Pyramids?
Because of culture. Human civilization is a cultural trait, not a biological one.
The whole Human Family is of the Black Originals. Brush up!!!
This is actually somewhat misleading. No race today is more 'primitive' than the other 'races'. We don't know what the original skin colour of
the earliest humans was, but considering that they evolved the low lattitudes, they were definitely dark skinned. Whether they would be recognized as
'black people' today is a different matter. Just because it was in africa doesn't mean that they stereotypically conformed to what we think of as
'african' today. For example, most black people in the west are descendants of a group called the Bantus, from western sub-saharan africa. In the
east, its a different group. In the extreme south, another group also. Eventually Bantu's migrate from the west down into the south.
In the north of africa, we see other groups of peoples. There is no one 'african type' that is the most primitive 'race' of humans or something
like that.
Maybe if the northern section was aryan in the time of highest Egypt we can see the white race coming out of Africa.
"aryan" is a pretty meaningless term, about as meaningless as 'black'. Aryan really, at most, describes a language group. The aryan languages
spread from central asia/iran a long time ago, but really have nothing to do with the spread of humanity.
