What Do John Edwards and Prairie Voles Have In Common? And It's Not That They Act Like Rats.

Prairie Vole
While Edwards is a rat, and a vole is a rodent, we have to delve deeper. What do they have in common? Well, John Edwards is prone to infidelity….he is prone to being promiscuous. And guess what…so are voles. Actually, voles are highly promiscuous. Maybe Edwards is too.
Yes, this is another study.
“A man's tendency to be unfaithful may be influenced by his genes, research suggests. Men who inherit a genetic variant that affects an important attachment hormone are more likely than usual to have weaker relationships and marital problems, and less likely to be married, according to the research. Their wives and girlfriends are also more likely to be less satisfied with them as partners. While the study did not look directly at infidelity, the findings suggest that male monogamy might also be influenced by variations in a single gene. The study's authors cautioned that any effect would apply only on average, and that it was impossible to predict whether any individual would be unfaithful or a bad partner on the basis of his genes.
The gene in question affects the receptor for a hormone called vasopressin, which plays an important role in social behaviour, pair-bonding and sexual attachment. Its effects were first characterised by studies of different species of voles. Although the meadow and prairie voles are close cousins, their sexual behaviour is dramatically different.
Like most mammals, male meadow voles are highly promiscuous, but male prairie voles are monogamous. When boy prairie vole meets girl, the two indulge in 24 to 36 hours of nearly continuous mating, which cements a bond that invariably lasts for life. When one partner dies, the survivor usually opts to remain celibate rather than find another mate. Male prairie vole brains contain much higher levels of vasopressin than those of meadow voles. There also genetic differences in the receptor for vasopressin in the two species. “
