I bring this up because some have claimed that I advocate a sole genetic progenitorship model for the first couple.
Their scrupulous work found that Jerry Coyne and others, in bullying Christians and Jews on how “we can dismiss a physical Adam and Eve with near scientific certainty,” were in reality poorly supported.
For the last forty years, population geneticists have repeatedly said that our population was never smaller than several thousand.
Could humanity have had its origin in a first pair, or did it have to come from a population of at least several thousand?
A bottleneck of two, or a first pair at our origin older than 500,000 years, is possible.
