Human Paleobiology provides a unifying framework for the study of past and present human populations to a range of changing environments. It integrates evidence from studies of human adaptability, comparative primatology, and molecular genetics to document consistent measures of genetic distance among subspecies, species, and other taxonomic groupings. These findings support the interpretation of human biology in terms of fewer number of populations characterized by higher levels of genetic continuity than previously hypothesized. Using this as a basis, Robert Eckhardt goes on to analyze problems in human paleobiology including phenotypic differentiation, patterns of species range expansion, and phyletic succession in terms of the patterns and processes still observable in extant populations. This book will be a challenging and stimulating read for students and researchers interested in human paleobiology or evolutionary anthropology.
