Women are Required to Cheat to Protect the Species

An interesting article from ScienceNOW Daily News involves the study of why females cheat – or try to mate with more than one male at a time. According to the multi-generational study of fruit flies, certain less-than-desirable traits can be eliminated by the competing sperm of multiple male partners. Thus, by mating with more than one male at a time, the odds are high that ‘good’ sperm will kill off the less-desirable sperm, so the offspring will be produced only by the 'good' sperm with the desirable traits. In this way, the species as whole is protected and strengthened.

I daresay that since humans are far more evolved than fruit flies and do not ‘mate’ only in order to procreate, the compulsion to be with more than one partner at a time is not about protecting and strengthening the species.

This is, however, yet another good attempt by science to justify bad behavior and poor judgment in humans. The previous attempt was aimed at cheating males.
