A factoid from David Reich (regret picking him up so late)
Almost every non-African has some Neanderthal ancestry (max 2%)
0% in sub-saharan Africa
Yet though Neanderthal zone was mostly Europe, modern Europeans have less Neanderthal ancestry (1.5%)
Other non-Africans at ~2%

This inter-breeding happened roughly 40-50K yrs ago in Near East and not Europe, as per Reich, soon after the early migration out of Africa of modern Humans
Soon after moving out, they met Neanderthals in the Near East, their long lost cousins who had left Africa 500K+ years ago

But Reich also believes the Neanderthal inheritance today is lower than it perhaps ought to have been because of natural selection
i.e.
The early hybrids of Neanderthals and modern Humans had lower fertility as compared to the rest of modern Humans

This makes me wonder -
Do genetically distant populations on a smaller timescale exhibit lower fertility when they interbreed?
Say Armenians and Indians...

Reich says no, based on analysis of inter-racial mingling in America in the past 400 years of West Africans and West Europeans
But wondering if there's something to this.
Maybe it needs more analysis
