> It is one of the reasons why 90% of human genetic diversity is within groups and only 10% is between groups.

Can you clarify what this means? I’ve heard it a bunch and I can imagine scenarios that this statement could describe. But also, a naive interpretation doesn’t make any sense.

It just means intra-group genetic diversity (i.e. between individuals) is far greater than inter-group genetic diversity (between populations)

Inbreeding fails to gaurentee genetic isolation/differentiation. Offspring may still have more in common with someone on the other side of the planet.
