> “For example, all present-day populations show about 2% of Neanderthal ancestry which means that Neanderthal mixing with the ancestors of modern humans occurred soon after they left Africa, probably around 50,000 to 55,000 years ago somewhere in the Middle East.” I gotta wonder what people are thinking when they write this stuff. I mean, "Neanderthal mixing with the ancestors of modern humans occurred soon after they left Africa". Do they imply that those whose ancestors never left Africa are not "modern humans"? I doubt it. So they're just being sloppy.
