“In broad strokes, the modern human population evolved from a merger of two ancient groups around 300,000 years ago, roughly 80% from one, and 20% from the other. The uniformity of this signal in all living populations suggests that it was a true formative event.” www.johnhawks.net/p/modern-hum...

Hi John, thank you for sharing your article - it's a fascinating read! I'm wondering If you've got copies of the Alan Rogers and collaborators, and Hrushikesh Loya preprints - can't seem to locate them online - as these sound really interesting.

"If we assume that both stems ended up archaic humans, in the broad sense, then they must have evolved that way simultaneously from earlier, H. erectus-like ancestors..." Really interesting paper! Q: So a potential origin for (now extinct) population B is a separate evolved line of Homo Erectus?
