exactly we as designed to have more children because up till 1000 years ago Men stastically lived to be 35. so we had to reproduce.
The wild thing is that your descendants are unlikely to be alive 400 years from now but your ancestor of 400 years ago genes survived because he had a gang of kids.
You read european royal bloodlines and they died out many many times and they tried to preserve it because although some dudes are successful in having a lot of kids some of his kids will have one or no children.
It's wild that you're way more related genetically speaking to your female ancestor of 500 years ago than you are to your Male ancestor because almost every woman has children less than half of Men globally and historically speaking has children.
Finally there's the FBA debate. Black Americans will likely be Argentina'ed in 200 to 300 years at the rate we're going 53% of Black American Men are single and childless I think that 72% of Black American women have kids.
@Pull Up the Roots kinda corrected me but there's 2million babies born by Black women where the heritage could possibly be mixed or in question.
Again as Roots said it could be that the race of the fathers are not listed but also 20% of Black American Men are coupled to someone not Black American
