Fifty thousand years ago - merely a blip in evolutionary time - our Homo sapiens ancestors were competing for existence with several other human species, just as their precursors had done for millions of years. Yet something about our species distinguished it from the pack, and ultimately led to its survival while the rest became extinct. Just what was it that allowed Homo sapiens to become masters of the planet? Ian Tattersall, curator emeritus at the American Museum of Natural History, takes us deep into the fossil record to uncover what made humans so special.

Ian Tattersall, a highly esteemed figure in the fields of anthropology, archaeology, and paleontology, leads a fascinating tour of the history of life and the evolution of human beings. Starting at the very beginning, Tattersall examines patterns of change in the biosphere over time, and the correlations of biological events with physical changes in the Earth's environment.

To better understand the inner workings of our bodies and to trace the origins of many of today's most common diseases, we have to turn to unexpected sources: worms, flies, and even fish.
