This book offers a unique insider's perspective on the unfolding discovery of a crucial link in our evolution: Proconsul, a fossil ape named whimsically after a performing chimpanzee called Consul.

The Ape in the Tree is written in the voice of Alan Walker, whose involvement with Proconsul began when his graduate supervisor analyzed the tree-climbing adaptations in the arm and hand of this extinct creature. Today, Proconsul is the best-known fossil ape in the world.

The history of ideas is set against the vivid adventures of Walker's fossil-hunting expeditions in remote regions of Africa, where the team met with violent thunderstorms, dangerous wildlife, and people isolated from the Western world. Analysis of the thousands of new Proconsul specimens they recovered provides revealing glimpses of the life of this last common ancestor between apes and humans.

The attributes of Proconsul have profound implications for the very definition of humanness. This book speaks not only of an ape in a tree but also of the ape in our tree.

This is the most comprehensive approach ever made to the human skeleton as a biological entity. It provides a holistic view, from the molecular and cellular level up to functional gross anatomy. The book synthesizes the latest research in a wide range of fields, including forensics, anthropology, cell biology, orthopedics, biomechanics, functional anatomy, and paleontology. Throughout the book the skeleton's functional and dynamic aspects are emphasized.

The first part of the book focuses on bone as living tissue: its composition, formation, growth and remodeling capabilities, and mechanical properties. The second part examines individual bones in the human body, combining strictly anatomical information with discussion of the major functions of each body section. For example, the chapter describing the axial skeleton is paired with one on the mechanics of breathing. The final part of the book surveys the archaeological and forensic applications of skeletal biology, including the estimation of age, sex, race, and stature; the effects of fracture and pathology on bone; and the modes of reconstructing skeletal remains. Elegant, detailed illustrations of the individual bones from several views and of the regions of the skeleton enhance the text.

On the slopes of the Nariokotome sand river in Kenya, sifting through sediments more than a million years old, Kamoya Kimeu uncovered a small piece of a skull. Piece followed piece—facial bones, teeth, vertebrae—and little by little paleontologists put together the most complete early hominid ever discovered, a Homo erectus skeleton christened the Nariokotome boy. This phenomenal find, a milestone in the history of paleoanthropology, is fully documented in this remarkable book. Beautifully illustrated and richly descriptive, The Nariokotome Homo erectus Skeleton takes us into the field and the laboratory, and into the far reaches of prehistory, to show us what the fossilized remains of a young boy can tell us about our beginnings.
