Lucy Cooke


Lucy Cooke is a New York Times best-selling author, award-winning documentary filmmaker and broadcaster, National Geographic explorer and TED talker with a Masters in zoology from Oxford university. Her latest book BITCH was named one of the 50 best books of 2022 by the Telegraph.

“Cooke demolishes much of what you probably learned about the sexes in biology class. This may be disconcerting, even confronting for those who feel comfortable in the warm embrace of Darwinian order. But it’s also exciting, and fascinating, and very well might change the way you see the world.” Science News

Women aren’t the only victims of misogyny. For centuries female animals have been marginalised and misunderstood by the scientific patriarchy. In BITCH Lucy Cooke introduces the animals and scientists who are reinventing the female of the species. This critically acclaimed best-seller will change how you think about sex, sexual identity and sexuality in all animals, including us. One of the Telegraph’s top 50 books of 2022, BITCH was adapted into the BBC Radio 4 series Political Animals and is now on the syllabus at UCL, Princeton and other major international universities.
