You can explain a lot of our actions today if you go far enough back in time. Why are most children picky eaters, for example? Back when we were hunters and gatherers, children just couldn’t pick up some fruit or berries off of the forest floor and eat them. It could make them very sick and they could die. So when your kid doesn’t want to eat those peas, it’s his instincts telling him what to do.
The latest theory as to why some people are overweight is a similar story. It’s a survival mechanism. Those who had the genes to put on weight easily had a better chance to survive the winter when food was scarce than those skinny folks who couldn’t. Today food is plentiful and we don’t need those genes, but they are still with some of us.
Why both men and women have a tendency to cheat on each other can also be explained in terms of survival. Way back in prehistoric times the man had to impregnate as many women as possible for his genes to survive. Many of the babies died right after childbirth because of the tough conditions.
A woman would find a mate (much like today) to protect her and feed her and her children. But he may not be the ideal one to be the father of her children so she goes out and sleeps around to make the gene pool healthier.
This is shown to be true because her body will accept a stranger’s sperm much more readily than her mate’s. Also a man whose mate is away for more than three days causes his body to make millions more sperm. It assumes that she is going to be unfaithful while she’s gone.
This is also proven by looking at the animal kingdom. According to CNN: ” Once at the Toronto Zoo, my family witnessed a male orangutan picking nits off his baby’s hair, while the female was grooming herself under a tree. Can there be any clearer precedent, from an evolutionary perspective, for men to scrape the dinner plates while women get manicures?” Writes author Wendy Shalit.
She goes on to write that since most studies on infidelity are conducted by men, there seems to a slant on which examples of apes or gorillas and their behavior we use to justify men’s infidelity. She uses an example of the primate’s penis is longer and thicker than most species. Some scientists use this fact to explain male infidelity through evolution. But she says that men’s arms are longer and thicker than most women’s so what does it prove?
The author recommends that all women go to the primate center at the local zoo and observe for themselves. Maybe that’s not such a bad idea.
