• Volume I, Principles, Methods, and Approaches; incorporates the enormous advances that have been made in areas such as phylogenetic analysis, palaeoecology, and evolutionary theory and philosophy.
• Volume II, Primate Evolution and Human Origins; integrates primate fossil data with the vast amount that is now known about the behavior and ecology of living primates in natural environments.
• Volume III, Phylogeny of Hominins; deals with the fossil and molecular evidence for the evolution of Homo sapiens and its fossil relatives.

Charles M. Musiba is a Professor of Biological Anthropology at Duke University in the Department of Evolutionary Anthropology. He is also a research professor at the Evolutionary Studies Institute, University of the Witwatersrand in Johannesburg, and the Human Evolution Research Institute (HERI) at the University of Cape Town in South Africa. Charles Musiba is a Montgomery and Carnegie African Diaspora fellow with research focus on human origins in eastern Africa.

His work covers the following areas: taphonomy and paleoecology of Laetoli, evolution of upright posture and bipedalism, hominin behavior ecology at Olduvai Gorge, conservation of hominin footprints and animal trackways at Laetoli, and the evolution of the genus Homo in Eastern and Southern Africa (Laetoli, Isimila and Olduvai Gorge in Tanzania, and the Rising Star Cave in South Africa). Charles Musiba is interested in reconstructing past environments (4 million years ago to 250,000 years ago) using multiple proxy data and he is actively involved in conservation efforts and sustainable use of paleoanthropological resources in Tanzania through education and cultural exchange programs. Charles Musiba has extensively worked on the evolution of upright posture and bipedal gait in humans with emphasis on the interpretation of the 3.6 million years old fossil hominin footprints from Laetoli in northern Tanzania.

Andrew S. Deane is an Associate Professor (with tenure) at the Indiana University School of Medicine, Indianapolis, USA. He holds an M.A. in Biological Anthropology from the University of Toronto, Canada, and a Ph.D. in Paleoanthropology, also from the University of Toronto. His research focuses on questions of ape and human evolution. In particular, he is interested in the functional relationships between the mechanical stresses associated with dietary and locomotor adaptations and hard and soft tissue anatomy, and what these relationships might reveal about the paleoecology and evolution of fossil apes and early humans.
