Just what a crazy name because of this weblog. Any normal person would automatically believe that aside from combining a beverage of sperm and egg in a fertility hospital, if a female were being impregnated by a certain man, she should have had sex with him. Appropriate? But, sigh, reproductive life is not that cut and dry.

During the brand new guide “how come the Penis Shaped such as that? And various other Reflections on Being real,” psychologist Jesse Bering Ph.D. can make an elegant situation your progression associated with penis head developed as a way to fight the point that as a species we humans tend to have loads polygamy or at least something of “perceived monogamy.”

Contained in this interesting read, Dr. Bering defines the penis form as if it will be the earth’s most readily useful plunger and scraper.

“precisely the human being variety provides a unique mushroom-capped glans, and that is attached to the shaft by a thin tissue of frenulum,” writes Bering.

Then the guy continues on to explain that evolutionary anthropologists and psychologists imagine your huge glans forms a ridge the whole way around the shaft — a great device to scrape the interior regarding the vagina of every various other mans semen.

This would demonstrably put a guy’s very own child juice at an advantage. Scrape away the last guy’s ammo and shoot your rocket deep to the pussy.

There’s one problem.

What to do with that additional mans sperm that features gathered under the ridge of a mind and (in many countries) is actually properly put away at the perfect temperature under a foreskin.

The most obvious solution, however, is just take a shower, break the rules that foreskin and wash away your competition’s troops. If only all guys had been very hygienic.

Instead, remains of some other man’s semen can gather underneath the foreskin and get inadvertently kept inside the after that girl the person features intercourse with. Really. In accordance with Bering, possibly.

There you may have it. One study showed that around 10% of infants produced in US hospitals do not have DNA that matches the doting Daddy cooing at their unique hospital cradle.

Now you could surmise that a good amount of it is as a result of good old-fashioned cheating. But who had been unfaithful? Mom or the pops just who pulled various other people’s semen off their mistress?

Hmmm…makes one presume, does it not?
