    Isn’t there some sort of biological thing where you’re more likely to be sexually attracted to your relatives if you don’t know they’re you’re relatives

      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.

        And if my maths is correct, you only share on average 12.5% of your DNA with them

          your math may be wrong, because we have very similar genomes, even compared to complete strangers. hell, even between some species.

            Well, yes. I meant in the sense we share on average 50% with each parent/siblings, 25% with grandparents, etc. I should have said genetics instead of DNA.

        Groups often came together to party and marry people.

        There are even rules, like exogamy is common.

      All I could find on this is something called “genetic sexual attraction” [1], though Wikipedia contains arguments that it’s pseudoscience [1.1]. Here’s a Reddit post asking about this. [3].

      Related to this, I also came across the “Westermarck effect” [2] which appears to suggest that people who grow up together are less likely to be romantically attracted to each other [2.1].

        1. §“Criticism”

          Critics of the hypothesis have called it pseudoscience. In a Salon piece, Amanda Marcotte called the concept “half-baked pseudoscientific nonsense that people dreamed up to justify continuing unhealthy, abusive relationships”.[8] The use of “GSA” as an initialism has also been criticized, since it gives the notion that the phenomenon is an actual diagnosable “condition”.

          Many have noted the lack of research on the subject. While acknowledging the “phenomenon of genetic sexual attraction”, Eric Anderson, a sociologist and sexologist, noted in a 2012 book that “[t]here is only one academic research article” on the subject, and he critiqued the paper for using “Freudian psycho-babble”.

      Yeah, that’s weird: genetically similiar people are more attractive (as long as it isn’t too similiar)(people in stable relationships often look alike) but bigger genetical difference is better.
