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.
Could humanity have had its origin in a first pair, or did it have to come from a population of at least several thousand?
Honestly, the scientific establishment would do better by sticking to science.
A bottleneck of two, or a first pair at our origin older than 500,000 years, is possible.
I don’t think the study can claim all the things it does based on the evidence they have.
