Phrenology doesn't work

The black hole of the Yucatan yielded up a "Naia" skeleton; Discovery Future discusses it.

Naia was a woman, and had the pelvic birth-pitting to prove it; with, unluckily, the pelvic fragility which helped kill her, when she spelunked into a lower cavern. Her head looked like the Kennewick Man's: more Ainu, or European. Luckily for our sciences, modern scientody has recourse to DNA. Since, well, woman there's no Y-DNA so we can't say much of her paternal ancestry.

We can say instead for her mitochondrial D lineage. This is all over South America mostly today. So nobody is calling her a "Solutrean".

At least, I hope nobody is. Beachy Head woman, for those keeping track, was deemed African by phrenology. She was not. On the other hand they did have some Yoruba or Mende DNA in Updown; this girl (whose own mtDNA was European) was probably brought to protoEngland by the Meroving Franks (which is why you don't see me buttmad over mulatta puppettrice too-tall in mediaeval-static Knight of the Seven Kingdoms).

The overall message has to be: don't use skull shapes as a proxy for race or ancestry.
