The Last Human: A Guide to 22 Species of Extinct Humans

This is a look back at the many-branched tree of the human evolutionary tree. The many versions of human (all but one, Homo Sapien - us - being extinct). This collection is a thought-provoking. Most of the critters featured survived longer than we've so far been around. It's entirely conceivable that we could wind up one of the least successful man-apes dreamt up by nature. Also interesting is the notion that we shared space with closely related Neanderthal for some time. Strange how we've come to see ourselves as so unique, the evolutionary equivalent of an only child.
