>>14064470It is a socially constructed idiom to suggest that the brain is somehow seperate and superior to the rest of the body, it reacts and mutates just like the rest of the body does.
Any measure of man dropped into the middle of a neolithic Polish forest in late October would surely die before winter ends due to a lack of non-frozen water, a lack of warmth from the bitter cold, a lack of shelter from the pervasive rain and snow and lack of food in the barren and harsh environment.
This kind of biome /demands/ that a man prepare extensively for winter. That he should build sophisticated shelters. That he should stock fire wood. Stock food whilest the elements allow it to grow. These tremendous pressures almost unimaginable to our priviliged lives were the reality for our white ancestors, so great and awful were they that it persuaded him to continually strive to improve his situation through enginuity. And so the white man advanced and advanced as his environment refused to allow him to be lazy.
The black man, however, survives in his environment all year around in the jungles of sub-saharan africa with a neverending supply of fruit, meat and fresh water. His primary instincts enough to enable him to survive, so that he may graze on the land like the bison and hunt on it like the tiger, year in, year out.
To suggest that hundreds of thousands of years of this has had no effect on the brain of these two sub-species is not ignorance, it is lunacy.
