[ExI] Out breeding

" The team also examined evidence of where the people had grown up by
analysing the combination of different forms of strontium in their
teeth. The ratio of strontium isotopes depends on a person's diet
during childhood and reflects the dominant rock types in the area.
While the men and children had a strontium profile that indicates they
were raised nearby, the women came from outside the area.

" Pike said this was evidence of a patrilocal society, where families
"married out" their daughters, either to avoid inbreeding or build
allegiances with neighbours."

Some time ago I read a detailed account with more individuals.

But the thing that amazed me is that people had figured out long ago
that inbreeding was a bad idea and went to considerable trouble to
avoid it.  (Like importing wives from a long distance.)

I wonder if they did the same with farm animals.
