Africa is MEDICALLY RETARDED! 😐

I mean a lot of blacks did immigrate to South America after colonization, so maybe thats where they all ended up mixing in the most. I find it very hard to believe the South Americans are sub-80 IQ since they were at least able to maintain a civilization, albeit often one based on sacrificing the children of the tribe across the border to the rain god to make the crops grow good.
