This was such a delightful book, full of fascinating science and history. Ever since Charles Darwin cherrypicked his data to suit Victorian sensibilities about gender roles, schools teach that the female of any species is generally a meek, nurturing caretaker while the male gads about hunting, fighting, and flaunting bright plumage. Cooke goes into the field with many different scientists to observe the many ways that creatures in nature defy this theory, and also digs into the science to show that general assumptions made by observing limited species are far from universal. The content sounds dry, but Cooke’s writing style is super enjoyable. Really great read.
