Science does not support the idea of pure races with ancient origins yet far-right white supremacist ideology is on the rise in Europe, North America and Australia. It appeals to a racist notion whereby many white supremacists see themselves as members of a “pure” race that is at risk of dilution and contamination.
In the past few years, genetic sequencing of ancient and modern humans and related species has given us a flood of new information about how human populations have evolved. The evidence reveals a history of ongoing genetic mingling, due to interbreeding between different populations and even species. Humans from different groups had children together, and even with Neanderthals and members of other now-extinct hominin species. This mingling occurred constantly in the long process of human migration across the globe. Europeans inhabit one region of a large genetic continuum and are no more or less “pure” than any other population.
In short, the idea of a pure white race has no basis in genetics. Lightly pigmented skin, hair and eyes are simply an adaptation to northern European climates (and represent an inferior adaptation in equatorial regions). These features exist in a background of countless other genetic influences borrowed from many populations, old and new.
