There's been a lot of discussion about the book Sex at Dawn across the internet. It's written by Christopher Ryan and Cacilda Jethá who are described as "renegade researchers" in the press release for the book. And what's the book about? It's evolutionary psychology at its finest, trying to explain modern behaviors with "just so" stories about what our ancestors did. It's largely concerned with polyamory and explaining how we're evolved for it and therefore it's a natural state.
They make frequent references to bonobos (AKA "sex chimps") as examples of how they think humans should behave, or at least how they think early hominids did behave. Many of the problems we suffer from today, they claim, are the result of moving away from this natural state.
I think it's pure, unadulterated bullshit.
Calling something natural in no way makes it legitimate. It doesn't matter if something is present in animals or not or if our early hominid ancestors did it or if everybody was doing it right up until 1921. Humans are gloriously capable of overcoming animal behaviors and altering ourselves based on culture.
Things which are present and therefore "natural" in populations of the family Hominidae consisting of chimpanzees, gorillas, humans and orangutans:
- Killing and eating your offspring.
- Rolling around in the dung of your prey.
- Throwing your own feces at neighbors.
- Rape.
- Necrophilia.
- Bestiality.
- Hunting animals closely related to you.
- Picking bugs out of the hair of your loved ones and eating them.
- Having sexual relations with your own offspring, parents or siblings.
- Murdering the offspring of a female to induce her to copulate with you.
- Same sex activities.
- And, oh yeah, polyamory.
When your opponents tell you what you're doing in the bedroom is unnatural, they're probably wrong. All sorts of stuff happens in nature. Dredging up evidence from animal behavior (or applying evolutionary psychology) does not strengthen your position, because you're arguing against something stupid to begin with.
People are people. We don't have to justify our choices by comparing ourselves to creatures that fling poop and try to get blowjobs from frogs.
