Human Origins

At the beginning of this book, the author states, "The aim of this book is to break the complex human story into bite-sized chunks, to highlight the broad trends and the major disagreements--and there are many disagreements...I have also tried to highlight how much our understanding of human origins has changed--and continues to change--and how, in some ways, palaeoanthropology showcases some of the best features of scientific inquiry..." (p6)

Does she succeed at the task she has set for herself? Indeed she does! She skillfully weaves the many threads of the story of human origins into a very readable, informative, fascinating narrative. Along the way, some threads get dropped and new ones picked up as more evidence becomes available. The search for the definitive story of how we--Homo sapiens sapiens--became the last homo species left will probably never be completely understood. The clues are random and necessarily fragmentary. We only have what turns up in the archaeological record. Then there is the interpretation of what is found, which often leads to disagreement between scientists. There is broad agreement that anatomically modern humans have been around for about 300,000 years, but how we got to that point and what happened to the other human species is still being explored. One 'fun fact' in the book was that Homo sapiens is the only hominin species (the lineage of species that diverged from chimpanzees 6 to 7 million years ago and resulted in us) to have a chin, as far as scientists know, and they don't know why.

This book is a great overview of the current state of thinking about human origins. It explains things without getting deep into jargon--general readers will find the book fascinating, highly readable, and informative. My one quibble was the explanatory boxes that were placed in the middle of the text. They provided important information, but the placement did interrupt the narrative flow for me, so I ended up just reading each chapter, then going back to read the text within the boxes. That's a minor issue, though, and about organization, not the excellent book itself. I highly recommend this book.
