Ian Tattersall is widely regarded as one of the rare eminent scientists who is also a graceful and engaging writer. In this extraordinary new work he attempts to answer the most controversial questions on human origins: What makes us so different? How did we get this way? How do we know? Guiding readers around the world and far into the past, Tattersall examines and explores evolutionary theory, a science based not on a finite set of conclusions drawn from overwhelming evidence, but rather our evolving effort to make sense out of a handful of incomplete fossil remains.

Brimming with delightful stories and scientific wisdom, this exquisite book offers fresh insight into the fundamental questions of our origins--and our evolutionary future.
