Pair-bonding – the species neutral term for marriage or social monogamy – is one of the things ingrained in our very being and is as natural to us as breathing. It’s something all of us are programmed to partake in. Believe it or not, that’s more of a feature, strengthened with every one of our procreative iterations, than a vestige. Simply put, people with a knack for pair-bonding ended up living long enough for the successful survival of their immediate descendants and for a good reason – we suck at everything. Apart from our incredible thinking capabilities, there is nothing we can do that other animals couldn’t better. The survival of humanity isn’t simply enhanced by this practice; we don’t stand a chance without it. As long as a significant portion of the human population keep doing it, we can be assured that humans will continue to exist.
