Second degree cousins is not that close though. If every generation has three children, that’s 27 persons. I thinks that for most of human history excluding second degree cousins from the acceptable partners pool would have been impossible. Communities were not that big.

I can’t stop laughing.
That’s how it’s phrased in many other languages, german for example.

Of the variable alleles, not all DNA
iirc 90% of dna is the same even between humans and plants. (Don’t quote me on that)
Groups often came together to party and marry people.
There are even rules, like exogamy is common.
