From Karen E. James, PhD, evolutionary & developmental geneticist at The Natural History Museum in London, England:

“Seamlessly blending science, sex, and humor in his book, Sperm Are From Men, Eggs Are From Women, Joe Quirk tempts us with the promise of sexual revelation, and then delivers with an alternately hilarious and astonishing primer on the modern evolutionary theories of human sexual behavior. Quirk’s charming combination of corny puns and dry wit leads us, laughing, through what might otherwise be some daunting scientific territory. He plays peek-a-boo with our oldest, most primal urges, triple-dog daring us to confront the possibility that our desires, jealousies, fetishes, and even our deepest emotions are merely the products of our primate past. All who accept the dare will be transformed into scientific thinkers, for observing how we deviate from Quirk’s evolutionary stereotypes– and wondering why– is perhaps the most tempting exercise of all.”
