High rate of extrapair paternity in a human population

What an unwieldy title.

But fascinating to see how much non-marital pregnancy varies depending on culture.

In Western culture, for example old UK traditions, there was a much stronger focus on inheritance, so extramarital kids were branded Bastard or Whoreson. https://en.m.wikipedia.org/wiki/Bastard_(law_of_England_and_...

It appears that in cultures without the need to insure blood lineage for political reasons, people were much more tolerant towards those kids.
