You don't know what homogenous means, it doesn't mean identical, but mixed up evenly. The haplogroup you posted is descended from Europe and migrated to Asia. If the races in the USA were left to their own devices they would also be homogenous after maybe 200.000 years or so - because the distance between European and Sub-Saharan African is considerably larger than between Paleolithic and Neolithic European.
You're indoctrinated by race-mixing propaganda, or you're a non-white/mutt yourself, and refuse to look the truth in the eye. I'm not gonna waste my time any further educating you, everyone can do his own research.
