"Rutherford describes [The Book of Humans] as being about the paradox of how our evolutionary journey turned 'an otherwise average ape' into one capable of creating complex tools, art, music, science, and engineering. It's an intriguing question, one his book sets against descriptions of the infinitely amusing strategies and antics of a dizzying array of animals."—The New York Times Book Review

Publisher's Note: The Book of Humans was previously published in hardcover as Humanimal.

In this new evolutionary history, geneticist Adam Rutherford explores the profound paradox of the human animal. Looking for answers across the animal kingdom, he finds that many things once considered exclusively human are not: We aren't the only species that "speaks," makes tools, or has sex outside of procreation. Seeing as our genome is 98 percent identical to a chimpanzee's, our DNA doesn't set us far apart, either. How, then, did we develop the most complex culture ever observed? The Book of Humans proves that we are animals indeed—and reveals how we truly are extraordinary.
