Why do giraffes have such long necks? Why are zebras striped? And why does the clitoris of the female hyena exactly resemble and in most respects function like the male's penis?

Deploying the latest scientific research and his own extensive observations in Africa, Léo Grasset offers answers to these questions and many more in a book of post-Darwinian. Complex natural phenomena are explained in simple and at times comic terms, as Grasset turns evolutionary biology to the burning questions of the animal kingdom, from why elephants prefer dictators and buffaloes democracies, to whether the lion really is king.

The human is, of course, just another animal, and the author's exploration of two million years of human evolution shows how it not only informs our current habits and behavior, but also reveals that we are hybrids of several different species.

Prepare to be fascinated, shocked, and delighted, as well as reliably advised-by the end, you will know to never hug the beautiful, cuddly honey badger, and what explains its almost psychotic nastiness.

This is serious science at its entertaining best.
