History shows clearly where all the races emerged from except the Anglo. I watched a lecture recently claiming Europeans (and the Aryan) bloodline is not separate from Asiatic bloodlines but then the genealogy doesn't support it.

Archeology does support various human species including Neanderthal that competed heavily before homo sapien sapien won the battle. Likely slaughtering it's way to the top since humans are so violent.

I think that world beyond the North exists.
White is an anomaly on Earth (the Earth "we" know.)
