From homosexual penguins and sex-transitioning fish to pregnant male seahorses and sexually dominant female bonobos, there are thousands of species that defy our expectations of gender and sexuality. Director Drew Denny takes the nature documentary to a whole new level in this eye-opening and entertaining expedition to the places David Attenborough overlooks, where giant duck penises and corkscrew vaginas take center stage.
Turns out Darwin wasn’t right about everything. He nailed that theory of evolution, but his understanding of gender and sexual diversity in the animal kingdom was more than a little misguided. Turns out the natural world is way more diverse and complex than he — or your high school biology teacher — may have led you to believe. Meanwhile, many unsung contemporary scientists, like evolutionary biologists Joan Roughgarden and Patricia Brennan and primatologist Amy Parish, have been zealously studying animal behavior and anatomy and exposing the myth of the gender binary for decades, despite ongoing resistance to their findings from the research establishment.
