      Meh. True monogamy is quite rare in mammals.

      Used to think monogamy was very common in birds, but IRC thanks to DNA testing, we now know plenty of baby birds have a different daddy. Ie. they raise the baby together, but they have an open relationship and impregnate/get impregnated by other birds.

      Apparently that’s surprisingly rare in humans.

        Less that they “have an open relationship” and more that the birds sneak around behind each-other’s backs. Males go off and try to sneakily impregnate other females, females sneak around and try to get impregnated by other males. You find it in apes too.

          Isn’t this anthropomorphizing, though? Is there evidence that the mates would experience emotional distress if they learned their partners were “cheating” on them?

          Being in a consensually monogamous relationship, I know I would and my husband would, but how much of that is cultural? I’m not really convinced it’s something that’s ubiquitous in the animal kingdom, though if you have a source about this that discredits my (admittedly amateurish) hypothesis, I’d be open to learning more.

            Sure, but saying “have an open relationship” is also anthropomorphizing. Also, sneaking around describes what happens much better. I don’t know what it looks like with birds, but with apes when a non-dominant male mates with a female, they have to sneak around to do it. If the dominant male catches the non-dominant male he’ll attack him.

            Here’s an example from monkeys:

            I haven’t found articles about chimps and gorillas, but I remember it being similar.
