Nature's Nether Regions

What the Sex Lives of Bugs, Birds, and Beasts Tell Us About Evolution, Biodivers ity, and Ourselves



The story of evolution you've never heard before: the amazing diversity of form and function in female and male genitalia including human ones.

A tour of evolution’s most inventive—and essential—creations: animal genitalia

Forget opposable thumbs and canine teeth: the largest anatomical differences between humans and chimps are found below the belt. In Nature’s Nether Regions, ecologist and evolutionary biologist Menno Schilthuizen invites readers to discover the wondrous diversity of animalian reproductive organs. Schilthuizen packs this delightful read with astonishing scientific insights while maintaining an absorbing narrative style reminiscent of Mary Roach and Jerry Coyne. With illustrations throughout and vivid field anecdotes—among them laser surgery on a fruit fly’s privates and a snail orgy—Nature’s Nether Regions is a celebration of life in all shapes and sizes.

Praise for Nature's Nether Regions

Praise for Nature's Nether Regions

"A very nice book; perfect for reading on the plane."
--Isabella Rossellini

"A closer look between the legs (or, in the case of the Australian velvet worm, on the head) to explore what the sex lives of various creatures can teach us about reproduction, diversity and human sexuality.... I actually missed my stop on the train this morning because I was engrossed in the chapter about duck sex."
--Lindsay Abrams, Salon

"From the very first page, Menno Schilthuizen makes us both laugh and think about the bewildering genital variation in the animal kingdom. We laugh at the outrageous shapes these organs take, and think about the central issue of this book: how genital anatomy advances male and female procreation. An exhilarating and most informative read!"
--Frans de Waal, author of The Bonobo and the Atheist

"When writing about genitals, it is difficult to find the correct balance between dry scientific description and pure titillation, but ecologist and evolutionary biologist Schilthuizen, in this remarkable book that explores the evolutionary origins of sex organs, succeeds in finding exactly the right tone.... Schilthuizen's entertaining work reminds us not to take 'the mechanics of sexual intercourse' for granted."
--Publishers Weekly

"A provocative voyage on the 'vast ocean of sexual function beyond the quiet backwater that we humans find ourselves in.'"
--Kirkus

"The science of genitals is a relatively new field for biologists, who have long overlooked the evolutionary importance of species' private parts. Biologist Schilthuizen balances the silly and the serious to describe researchers' latest efforts to understand how 'evolution has graced the animal kingdom with such a bewildering diversity of reproductive organs.' Schilthuizen tours some of nature's weirdest inventions, such as the chicken flea penis, which is 'actually a profusion of plates, combs, springs, and levers' and looks like 'an exploded grandfather clock.'"
--Scientific American
