According to their simulation, an ancestral population of 60 women and 30 men were breeding in Africa before humans left the continent. The numbers fell to around 25 women and 15 men breeding at the time of the first migration of Homo sapiens, around 70,000 years ago.
As modern humans moved into Europe more than 45,000 years ago, the number of mothers may have outnumbered fathers by around 100 to 30, according to Stoneking.

Hadde vært interessant å visst hvordan fordelingen er i dag.
