""Reproductive anatomy is more variable than commonly understood, according to this eye-opening study....The raft of research convincingly debunks the idea that sex anatomy has much consequence on behavior, character, or cognitive ability...and the illuminating discussions of animal biology demonstrate the profound diversity of sex expression in nature.... [Sex is a Spectrum is] a resounding refutation of the idea that there’s anything natural about the gender binary."" * Publishers Weekly * ""Fuentes . . . flexes his considerable powers of communication to lay out the argument that human gender cannot be understand as binary. . . . [Sex is a Spectrum] is a highly readable popular science investigation of sex and gender, rich with 'did you know' moments for those who love the extraordinariness of nature and human bodies."" * Library Journal * ""Fuentes does a good job of summarizing what we know about the evolution of sex.... Sex Is a Spectrum will be important for introducing a wide readership to the nuances of scientific understandings of variability in sex and of the biocultural constitution of humans... there is much for biologists to appreciate in the book as well.""---Malin Ah-King, Science
