We seldom think of ourselves as “purely biological” organisms, but it’s a good exercise sometimes.
If we take our conceptions of love, sexuality, and self-actualization out of the picture, we occasionally stumble upon some really interesting questions about our basic biology.
There really are two kinds of people in the world. Those that give in to the urges for monogamy and those that give in to the urges for non-monogamy. Both urges are real, strong, and based on our evolutionary past. But in the end analysis, our bodies, and the oldest remnants of our evolutionary past, demonstrate that females are built for non-monogamy. It’s a pesky truth, but denying it is just… well… denial.
