"The Four Races of Man: Red, Yellow, Black, White"

[Igel]

5. Most such divisions are facile.

Australian Aboriginals probably separated from the main trunk of humans before the groups that became Europeans and Asians did. In other words, in some ways they're more divergent.

Khoi-San are at least as distinct from sub-Saharan blacks as the latter are from the rest of humanity. Anthropologists used to say that until the primarily Western obsession with skin color triumphed over all the other differences. One side-effect that that the on-going genocide of that former "race" suddenly vanished as an issue, except among those studying those groups' cultures and languages.

It rather leaves out where to put Negritos, as well as other groups from S. India and nearby areas, even ignoring the current trend of contrasting everybody with whites (however re-re-defined) for American political/ideological purposes. I mean, that four-fold split erases well over a billion people who we don't consider "white" but certainly are not "black" or "yellow." (And somebody will take issue with "Negrito", I'm sure, but while they're a diverse group there's still some uniformity to them and it's unclear how else to refer to them.)

But it sounds good.
