### I completely disbelieve this estimate. Major races split between 100+
and 50 kyr ago, with zero gene flow between the most geographically
isolated subgroups. There must be multiple Pygmy ancestors at 15 kyr who
made absolutely no contributions to Aborigine or Amerind populations and
vice versa.
