(More customer reviews)Poirier and McKee present a wealth of information on the history of human evolution. They outline the methods of dating, identifying and assembling hominid fossils. Dating is shown to be, within the ranges of accuracy, nearly an absolute with today's technology. With the age of the fossil[s] established and the parts identified, the fossil may then be placed in its proper location on the human family tree. Poirier and McKee spend the remainder of the book describing the concepts, controversies and resolutions associated with that final step. The material requires attentive perusal, but the interested reader will be richly rewarded.
Early hominid fossils were chronologically located by stratigraphy - the position of the fossil in the rocks in relation to other, known, remnants. The early finds were often located in poorly identified areas, or mistakenly dated for a variety of reasons. Paleoanthropologists of an earlier day lacked the technology available today. Worse, they were often unaware of the need to examine the likely environment of the time the fossil was laid down. As the authors point out, this misunderstanding led to misinterpretation of how evolutionary relationships were structured. Today's "digs" are the subject of multi-discipline effort, with botanists, geologists and other fields represented. The more comprehensive picture laid out by these environment associated with the find allow a firmer footing on our ancestral lineage.
While that assertion sounds promising and our heritage is now viewed with confidence, nothing could be further from the truth. Where the human evolutionary tree once looked rather simple, with but a few offshoots extending from the central trunk, the improved accuracy of dating shows many branches. How many of these truly belong on the main branch and how many led to the dead end of extinction is what gives this book its real value.
Paleoanthropology has been among the liveliest of sciences. The debates and controversies have left academic halls and achieved public exposure. Poirier and McKee present the contentions of most of the major figures in the field with circumspection and clarity. With each new find, various interpretations arose, researchers attacking and defending positions from various foundations. The authors give each assertion its due, with resolution occasionally based on their own assessment. They have no hesitation in stating their own position, but it's given with justifications. Counter arguments are made with confirming data. Evidence is shown, but not nearly as strongly as the need for new results. This book, in many respects, reads like an academic work, but that in no small part is due to the authors'
call for more work in the field.
It would be unfair to say that every hominid fossil is given the authors' personal scrutiny, but the impression is proximate. Nearly every major site, with many of the associated prime fossils are described, sometimes with maps and photographs. The illustrative material, maps, diagrams and photographs are invaluable. About the only missing element is a single skeleton and skull with the bones frequently discussed in the book labeled. While many are, they must be examined out of context in many cases. If you have the anatomy, you won't need the information, but the rest of us require the crutch.
For anyone wishing to keep abreast of the research in determining where humanity comes from, this book is a treasure. Given the amount of information the authors had to cope with, the work is clear, unequivocal and immensely valuable. While not a light read, there's little to obstruct even the novice reader. The material is well organized and presented with a clear, straightforward style. Since the authors' aim is to explain [and recruit!] without perplexing the reader or seeking adherence to positions, they have produced a book that will endure.

Understanding Human Evolution (5th Edition)For the one-term course in human evolution, paleoanthropology, or fossil hominins taught at the junior/senior level in departments of anthropology or biology. This new edition provides a comprehensive overview to the field of paleoanthropology--the study of human evolution by analyzing fossil remains. It includes the latest fossil finds, attempts to place humans into the context of geological and biological change on the planet, and presents current controversies in an even-handed manner.
