And even at 80%, early humans already had it really rough. There seems to have been 2 near extinctions of modern humans in the far past, so when the population is about 1000, having 200 not contribute is pretty big. Especially with the higher mortality rates early humans had in regards to birth.
It’s more likely the percentage started extremely low and increased over time as population stability increased, since then it would reach a point where 10-20% not having kids wouldn’t be as big a deal since there would now be hundreds of thousands or even over a million.
I don’t think the human race would have survived 50/50 split
So bi and pan people don’t fuck and make babies?
That would imply at least 30% is bi/pan.
