"Are Humans Meant to be Monogamous?"

Are they deliberately publishing this dreck?

From LiveScience:

Social monogamy is a term referring to creatures that pair up to mate and raise offspring but still have flings. Sexually monogamous pairs mate with only with one partner. So a cheating husband who detours for a romantic romp yet returns home in time to tuck in the kids at night would be considered socially monogamous.

Beyond that, scientists' definitions for monogamy vary.

Evolutionary psychologists have suggested that men are more likely to have extramarital sex, partially due to the male urge to "spread genes" by broadcasting sperm. Both males and females, these scientists say, try to up their evolutionary progress by seeking out high-quality mates, albeit in different ways.
