What does it mean to be female? Mother, carer, the weaker sex? Think again. Whether investigating murderous meerkat mothers, same-sex female albatross couples, philandering female monkeys, menopausal orca matriarchs or the titanic battle of the sexes waged by ducks, Lucy Cooke exposes the sexist bias embedded in evolutionary biology and reveals the emerging truth about female animals. The bitches in BITCH overturn outdated binary expectations of bodies, brains, biology and behaviour, and showcase the extraordinary plasticity of sexual expression in nature.
