This book is a sequel to the famous Lucy which described finding an early hominid that challenged the then orthodoxy about human origins. In this book Johanson goes back to Olduvai Gorge and finds another specimen (less sensational), and takes the opportunity to review changes in the thinking in the field of human origins since his first book. ( )

This is about anthropology, first man, and human ancestors. It also discusses the battles between famous paleoanthropologists such as Tim White, the Leakeys, Donald Johanson, Desmond Clark, Raymond Dart, etc. ( )

The discovery in this book is not in the same league as the original, but it's still a well told story, and a good explanation of the growing interdisciplinary nature of the study of human origins. ( )
