Barry X. Kuhle, an evolutionary psychologist from the University of Scranton, has proposed a somewhat controversial explanation for women’s bisexuality, or “hetero-flexibility. Kuhle contends that, evolutionarily speaking, same-sex behavior allowed women to pair up in order to raise children.

"Being born with the ability to [be attracted to men and women] may have been beneficial to ancestral women," Kuhle tells LiveScience.

His hypothesis was recently published in the journal Evolutionary Psychology, and Kuhle suggests that women who were raped or fathered children with absentee dads may have formed relationships with other women, making it easier to rear offspring.

Not everyone agrees with Kuhle, however.

"It's an intriguing idea, but there is actually very little evolutionary evidence for it," said Lisa Diamond, a psychologist at the University of Utah.
