The Mayas' other ancestry

LindyScience (clumsily) translates some Italian, asking a question about the real translation she has in her head. The real translation is, Native American populations genomes do not show any contribution from non-American populations, with one exception: the Maya, to whose (al cui) genetic makeup 'Tuscan' and Bantu ancestors have significantly contributed. She asks how come the conquistadors only raped the Maya and not the other indigenes.

My answer is that the conquistadors didn't rape the Maya. Since we're on topic, they somewhat-famously failed even to conquer them, much...

The Spaniards in Maya lands lived among them as Maya. Vaguely recall a nineteenth century book about the Maya which noted some Spaniard villages in their lands who spoke only Maya and not Castilian (anymore). UPDATE 8/17: Daniel Brinton an Carl Hermann Berendt. Perhaps from the unedited Nombres Geograficos en Lengua Maya.

Spaniards elsewhere when they went mestizo got their kids to speak Spanish, not their mothers' languages. Where there was a pure "Indian" town, it has stayed "Indian".
