ICYMI: The August issue of National Geographic has this really great article:
The first Europeans weren’t who you might think

Those master race white Europeans are in for a huge wakeup call.

It also explains why some (perhaps many/most) of us “white Europeans” aren’t so pure white after all when we get out 23&Me/Ancestry results.

The idea that there were once “pure” populations of ancestral Europeans, there since the days of woolly mammoths, has inspired ideologues since well before the Nazis. It has long nourished white racism, and in recent years it has stoked fears about the impact of immigrants: fears that have threatened to rip apart the European Union and roiled politics in the United States.

Now scientists are delivering new answers to the question of who Europeans really are and where they came from. Their findings suggest that the continent has been a melting pot since the Ice Age. Europeans living today, in whatever country, are a varying mix of ancient bloodlines hailing from Africa, the Middle East, and the Russian steppe.

SPOILER: “pure Europeans” would be Neanderthals and they couldn’t hold off the “invaders” from Africa, the Middle East, and Russia/Siberia.
