At a time when people are testing the boundaries of just about everything related to sex and gender, The Sexual Evolution shows that diverse sexual behaviour is not a new development, or even a human one. It's the product of billions of years of experimentation throughout the animal kingdom.

Evolutionary biologist Nathan H. Lents takes readers on a journey from silent crickets to lesbian albatrosses to bonobos who kiss, revealing what this incredible array of sexual diversity can teach us. Amusing, enlightening and meticulously researched, this is a book that will demolish biases held by even the most open-minded among us.
