...genetic data revealed that the human variation we see is not a matter of hard types but small and subtle gradations, each local community blending into the next. As much as 95% of the genetic difference in our species sits within the major population groups, not between them. Statistically, this means that, although I look nothing like the white British woman who lives upstairs, it's possible for me to have more in common genetically with her than with my Indian-born neighbour.
