There are a lot of opinions roaming about the blogosphere regarding whether or not people are “supposed to be” monogamous. I’m going to try to take an in depth look at this topic from several points of view. Hopefully, by the time you’re done with this article, you’ll have some idea about what science says, and that will allow you to evaluate your own moral feelings and emotions against something a little more concrete. Before reading on, I do feel like I need to emphasize that descriptions are not instructions. I’m not in any way trying to tell you what you as an individual should do. Instead, I’m trying to give you something scientific on which to base your own decisions — something more than gut feelings. Humans are widely varied in their desires, so I certainly do not presume to tell you what yours ought to be.
To begin, I’m going to tackle human sexuality from both sides, male and female. This may seem the obvious choice, but just to be sure, let’s remember that sex is competition. Males and females have their own interests, evolutionarily speaking, and we have hopefully dispelled the myth that human intelligence puts us above other animals. Like chimps and dolphins and killer whales, we are very intelligent social animals, and examining our behavior is the same as examining that of any other creature. If we see a pattern of behavior, there is a reason for it. Anything that exists is a product of evolution, including our intelligence and our incredibly complex society. If we look well into our past, we will understand the mechanisms behind our behaviors. If we are lucky, we will be able to take the lesson of sugar consumption to heart, and we will be able to make some educated statements about what we should do if we want to achieve a particular result.
So, on to the question of monogamy. Before answering decisively, I must make a distinction about the word itself. There are two very different ways of asking the question – that of a social scientist and that of a sociobiologist. An anthropologist who speaks of monogamy is talking about marriage, or whatever cultural equivalent there might be. A species is monogamous if males and females have one official partner. This does not take adultery into account, nor does it account for serial monogamy, which is the practice of having one partner for a relatively short period, and then moving on to another partner. On the other hand, a sociobiologist who speaks of monogamy is speaking of the actual practice of mating. A species is only monogamous if it really has only one sexual partner. Any mating is considered part of the equation, and social institutions are not considered.
For the time being, I will be using the sociobiological application of the word. When I speak of polygamy, I am speaking of the practice of having multiple sexual partners, regardless of institutionalized or cultural norms. Similarly, monogamy will only apply when a species really does mate with only one partner. Just as in our mental exercise with sugar cravings, we must first understand how we behave, and then we must understand why. Only then can we begin to look at ourselves as individuals and begin to think about goals and how we should act if we wish to achieve them.
Finally, then, the answer to the question. Are humans monogamous? The short answer is no. We are mildly polygamous. The long answer requires addressing the question from various points of view. Culturally, we have always focused on a single marriage between a man and a woman, but there are two unavoidable facts that we must not overlook, even if they are incriminating or cause us personal discomfort. First, though marriage has virtually always been between one man and one woman, mating has not. Since the agricultural revolution, powerful men have virtually always kept harems. In fact, this practice has only fallen out of favor since industrialization. Contrary to the notion of the faithful middle class man, polygamy was not restricted to the very powerful. It was only institutionalized for them. Men have been cheating as long as they have been marrying, and not just a little bit. Cheating is almost as common as marriage, historically.
If we compare anatomy and biology, we find this conclusion to be valid. There is a clear and virtually indisputable link between the size of the testicles and the fidelity of the species. Ours are not large enough for a thoroughly promiscuous lifestyle, like the chimpanzee’s, nor are they as small as the most monogamous apes. Human males are not large enough, compared to females, to command harems in the same way as a gorilla. We are not antisocial enough to be as monogamous as gibbons. In all biological areas, we fall above the threshold of monogamy, and below that of outright polygamy. ---->>
