Reviews

“As a compendium of information on sex and gender diversity in the natural world, Roughgarden's is the richest and most authoritative book available, fulfilling a desperate need of readers both within and outside the scientific community . . . this book is going to have a huge impact.”
*Nature*

“This brilliant and accessible work of biological criticism has the potential to revolutionize the way readers conceive of gender and sexuality in the natural world. “
*Publishers Weekly*

“An insightful blend of biology and social science, this work presents a fresh evolutionary perspective on sex, gender, and sexuality, with widespread implications for modern societies.”
*CHOICE*

“The book is thought–provoking, even at times profound. . . . I hope this book will be widely read. It combines the combustible power of a keen intellect with powerful conviction and ethical courage. Scientists are trained to create the illusion of objectivity by hiding their hopes and expectations. Roughgarden tries a different approach, openly injecting her reasoned convictions and policy agenda into her analyses. I don't agree with all of her conclusions, but she has written an important and honest book about a subject that matters.”
*American Scientist*

“Throws open the animal kingdom’s closet doors.”
*Advocate*

“This extraordinary study strengthens the case for a liberal tolerance and blows open established moral and scientific certainties.”
*Scotsman*

“Brave . . . Evolution’s Rainbow succeeds very well at making the reader rethink their conceptions of social selection and nature.”
*Biology Digest*

“Evolution’s Rainbow not only enhances our knowledge of the natural world, it also offers an ethical way for such knowledge to be used.”
*California Wild*

‘A fascinating discussion of diversity in gender and sexuality across a wide variety of animals.”
*Pink Pages*
