Men aren't hard-wired to be unfaithful after all?

University of California researchers examined the fruit fly study by English geneticist Angus John Bateman in 1948, and proved that the long-accepted theory was incorrect.

The study, led by Patricia Adair Gowaty, a professor of ecology and evolutionary biology, found that females may be just as promiscuous as males, Daily Mail reported Thursday.

In fact, Gowaty said Bateman's study should never even have been published.

Musing on the reasons why the original experiment was never retried, Gowaty offered: "Our worldviews constrain our imaginations."

"For some people, Bateman's result was so comforting that it wasn't worth challenging. I think people just accepted it."

Bateman's 1948 paper became significant in the 1970s and has been cited in nearly 2,000 other scientific studies and yet despite the fact that science relies on multiple re-studies, it was never retried until now.
