Different races as the first step of speciation

AI Thread Summary
The discussion centers on the concept of race and its relationship to speciation in modern humans. It posits that different human races may have emerged after approximately 80,000 years of isolation. A key question raised is whether these races represent an initial stage of speciation, suggesting that if populations, such as those in Vietnam and Germany, were to cease interbreeding with outsiders, they could eventually evolve into distinct species. The conversation also touches on the timeframe for speciation, referencing the divergence of Neanderthals and modern humans around 600,000 years ago, while noting that interbreeding was still possible between the two species. The implications of isolation on genetic divergence and species formation are central to the discussion.

4) RACE AND SPECIATION It seems that different races of modern humans

arose after being isolated for about 80,000 years. Are different

races the first stage of speciation? That is to say, for example, if

the people of Vietnam and the people Germany stopped having children

with foreigners outside of their respective countries, would they

eventually become different species?

Even if one population of germans got isolated into two, they would speciate.
 
How long would it take? Neanderthals and modern humans drifted apart about 600,000 years ago, but according to some they could still interbreed...

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
