The primate tales that de Waal uses to discuss gender are both fascinating and enlightening ... But as an argument about humans, I found Different less satisfying ... De Waal sometimes stretches evidence to fit his claims ... When De Waal asserts that male apes and men are both judged by the width of their shoulders, he doesn’t even offer a footnote ... Sometimes de Waal’s evidence for a link between humans and other primates feels more like free association ... Different would have benefited from less free association and more sustained argumentation ... It is hard to tell from Different to what degree our genders have been shaped by history before and after our split from our fellow primates. None of this is to take away the value of the stories of Donna and the rest of the primates that have filled de Waal’s life. If you don’t know your bonobo from your gibbon, Different has many surprises in store for you, surprises that will leave you humble about complex primate evolution has been, and how much we have yet to learn about how it shapes our lives.
De Waal turns again to the ape world, this time to explore the connection between gender and biology. As I said, brave. Whether he’s convincing is another matter ... He points to differences in the behavior of male and female primates as evidence that biology explains more of human gender differences than many would like to believe. That is not necessarily a baseless argument, but de Waal never provides a concrete definition of 'biology' for us to consider ... An explicit definition of biology, by way of hypothetical genetic mechanisms, would have gone a long way in supporting the central premise ... Still, de Waal’s book is a valuable addition to the public discussion of sex and gender. Analyzing the behavior of close evolutionary relatives is a scientifically sound way to understand the origins of our own behavior ... Even if Different doesn’t provide satisfying answers to our questions about gender and sex, it is still a valuable collection of amusing, heartwarming and sometimes heartbreaking anecdotes about our animal cousins.
De Waal draws on a long career of investigating chimpanzees and bonobos—both equally close to humans genetically—to argue with wit and clarity against assumptions about sex and gender that generate inequality ... The author enlivens his pages with attentive, sometimes moving portraits of animals he has encountered as well as anecdotes about his own experiences as one of six brothers. Engaging, enlightening, and deeply informative.
