In 1987, a group of California scientists announced that they had traced the entire natural history of humankind to its single common ancestor, a woman who lived in Africa more than 200,000 years ago. Investigative journalist Brown tells the story, setting it in the context of recent paleoanthropic discoveries. For a general audience. Annotation copyright Book News, Inc. Portland, Or.
This book discusses the evidence that we are all descendants of a small band of humans who lived in Africa about 200,000 years ago. It was published in 1990, so it is dated--I am sure there have been updates to the science by now. It is a very interesting topic, unfortunately Brown concentrates way too much on the squabbles between scientists for my taste.
