Full of fascinating and bizarre cases of genetic mutation and irregularity, Mutants is an amazing exploration of the human form in all its beautiful and unique guises. Why are most of us born with one nose, two legs, ten fingers and twenty-four ribs -- and some of us not? Why do most of us stop growing in our teens -- while others just keep going? Why do some us have heads of red hair -- and others no hair at all? The human genome, we are told, makes us what we are. But how? Armand Marie Leroi takes us to the extremes of human mutation -- from the grotesque to the beautiful, and often both at the same time -- to explain how we become what we are. Through the tales of long-lived Croatian dwarves, ostrich-footed Wadoma tribesmen, sex-changing French convent girls, and many more wonders of human development, Leroi has written a brilliant narrative account of our genetic grammar and people whose bodies have revealed it.
