Finally, Scientists Discover Why Women Really Cheat (Read Here)

Scientists have claimed that women are programmed to do the dirty on their partner – but it’s all down to their biology. According to a new study, lusty ladies are “genetically programmed to have affairs” because monogamy is unnatural.

Instead scientists think the females have evolved to keep their options open at all times, meaning they constantly test relationships and remain on the lookout for better mates.

Researchers at the University of Texas claim women are predisposed to play away, but it’s so they can have “back up plans” if their current relationships fail. The desire to cheat stems back to our ancient ancestors who would have kept back-up partners on the sidelines incase their current squeeze died.

Senior author of the research, Dr. David Buss, explained: "Affairs serve as a form of mate insurance, keeping a back-up mate should a switch become warranted in the future.

"A regular mate may cheat, defect, die, or decline in mate value.

"Ancestral women lacking a back-up mate would have suffered a lapse in protection and resources."

The professor of evolutionary psychology reckons that women evaluate their lover’s “mate value” and then compare it against other single guys’ ratings.

Dr. David told the Sunday Times: "Lifelong monogamy does not characterise the primary mating patterns of humans.

"Breaking up with one partner and mating with another may more accurately characterise the common, perhaps the primary, mating strategy of humans."

Meanwhile there’s more evidence to suggest that cheating might just be in our DNA.

Some people believe there’s a cheating gene, or set of genes.

A recent study of 181 men and women by researchers at Binghamton University suggested that half of all people have a gene that makes them prone to sleeping around and being unfaithful.

Those with the DRD4 gene "were more likely to have a history of uncommitted s*x, including one-night stands and acts of infidelity" according to lead investigator Justin Garcia.
