Chimps like us

What is being a human animal about? Mary and John Gribbin’s competent and accessible book Being Human: Putting People in an Evolutionary Perspective (Phoenix £6.99 pbk, ISBN 1 85799 378 0) talks about how the minute genetic difference between us and pygmy chimpanzees can go a long way and why, in the end, the difference between ourselves and the dinosaurs may not be as big as we would like.
