Humans are most closely related to two Great Ape species: Chimps and Bonobos. Chimps have a classic alpha-male harem arrangement. So patriarchal and heteronormative, amiright? But Bonobos have a female-dominated social structure and are famous for being promiscuous sexually, with sex being used for barter, reducing tension, and just for fun. Both male and females engage in homosexual behavior. Groovy …

It must be great for beta male Bonobos to live in such a sex-positive culture, right? Not so fast. It looks like a lower percentage of male bonobos reproduce compared to Chimpanzees, and only the most dominant bonobos are successful at passing on their genes to the next generation.

Sexual selection is a bedrook thing that happens in most species that reproduce sexually. Most males of any species don’t reproduce, and this is by design (to weed out mutations that are not adaptive as quickly as possible). Our two closest relatives experience sexual selection (see links above), and we know that it’s historically been a thing with humans as well (80% of females humans vs 40% of male humans reproduced in the past). This should really be taught in high school biology in my opinion, since it’s more relevant to the lives of most humans than natural selection. You’re unlikely to die because you weren’t fit enough to get food or avoid a predator in a modern first-world society, but if you’re a male you’re still in a struggle against other males to get attractive enough that females will be open to your advances.

A sexually liberal culture doesn’t fix the problem for less attractive males, but instead exacerbates it. The parallel for Bonobos with the sexual revolution in human society is obvious. A society with more sexual freedom means by definition a society where females exercise their natural right to choose whom to mate with, and some males are left out in the cold due to sexual selection. Bonobos seem to deal with this partly by having ample homosexual sex. If it’s good enough for beta male bonobos, maybe beta male humans should give it a try?
