Absolutely! Obviously, if you asked 100 women what they were looking for in a partner, you’d get a wide variety of answers. From a biological standpoint, there are physical ideals in a partner that we notice subconsciously (for example, and it goes way deeper than this, men are most attracted to women with a diamond face shape, women are most attracted to men whose upper back and shoulders form a kind of inverted triangle shape). There are various other physical cues which we take in subconsciously, from proportion to symmetry, to hair and skin, etc.
Basically, our brains quietly process ‘ideal mate’ characteristics. As I said, there is a long tradition of monogamy because it was a really good solution to meet human needs at the time. The female is generally weaker and less muscular, so there would always be a male around to protect her and her offspring. Physically, men and women have diverted and evolved to fill our own particular social and biological niches. There was a need for someone to care for children and the elder members of the society, as well as a need for someone to protect the settlement and be strong enough to go out and hunt.
Over time, society has worked itself to fit basic human needs. I wouldn’t be surprised if the first hominids didn’t have as much of a sexual dichotomy, because I feel like we’ve evolved physically to be how we are nearly completely out of the roles we’ve assigned each other.
I remember reading a couple of interesting studies years ago, at the height of the whole ‘is monogamy in our nature or not’ debate. What’s fascinating to me is what our bodies do without our control or knowledge. This study posits that the shape of the human penis has actually evolved to be a sperm displacement device (“the penis may have evolved to compete with sperm from other males by displacing rival semen from the cervical end of the vagina prior to ejaculation”).
Another study (which I can’t find, only references to it) found that when men spend more than 3 days away from their partners (when their partners could get the opportunity to mate with other males), the number of sperm cells per similar sperm volumes rises sharply.
These things, along with studying chimpanzees and other primates, would make it seem like we have evolved in response to polygamy, not monogamy.
