you are introducing EVOLUTIONARY FORCES------
a kind of genetic change based on natural selection----
blacks were not enslaved here in the USA long enough
for that sort of thing to happen
Not a natural evolution. A sort of social evolution spurred by a concerted effort of those in power to shape the oppressed group. I should have made it more clear, that some intelligent, ambitious, and independent-minded black folks remained alive, but learned to hide those "undesirable" traits. What are the odds they raised their children to be intelligent and ambitious, when those traits were considered dangerous?
Hell, I know someone now who can remember his mother telling him that while he was in the South as a child, to not look white people in the eyes. It was THAT serious, how they acted and what kinds of behaviors were encouraged and discouraged by the group in power.
