...the boy’s DNA matches that of Western Europeans, showing that during the last Ice Age people from Europe had reached farther east across Eurasia than previously supposed.
Oh? People from eastern Asia couldn't have populated Europe?
I suspect it's more likely people from Europe traveled eastward to what's now Siberia, but have to wonder how sure we actually are Homo sapiens originated in Africa and reached Europe before various parts of Asia. Just because the oldest pre-hominid fossils we've found thus far were in Africa doesn't mean that's where we actually originated.
Does that sound too far-fetched? How much of what we believe we know today would have seemed equally ore more far-fetched 100 years ago?
Just finished reading two books about Atilla the Hun (400s AD). Populations ranged back and forth across the great Eurasian plains over the centuries and millenia, depending on weather conditions and population growth among other things. My son had his 6 wisdom teeth removed and the dentist asked if he had Esquimo blood. His father was 1/16th Cree Indian (a Canadian tribe) The rest was northern European from Scotland, Prussia, and Wales. I think his father had visible traces of Neanderthal blood as well.
