A major debate in anthropology concerns the relationship between anatomically modern humans and earlier "archaic" humans including the Neandertals. What was the origin of modern humans? Did we arise as a new species in Africa 200,000 years ago and then replace archaic human populations outside of Africa, or are our origins part of a single evolving lineage extending back over the past two million years? In addition to fossil and archaeological evidence, anthropologists have increasingly turned to using genetic data on living populations to address this question. Patterns of genetic variation within and between living human populations are felt to contain clues as to our species' evolutionary history, and provide a reflection of the past. This book reviews the modern human origins debate focusing on the genetic evidence relating to our origins, including genetic variation in living humans and recent discoveries of ancient DNA from fossil specimens. Following a brief introduction to the problem and a review of evolutionary genetics, the book focuses on gene trees and the search for a common ancestor, genetic diversity within populations, genetic distances between populations, the use of genetic data to reconstruct ancient demography, and Neandertal DNA. The main point of the text is that although the genetic data are often compatible with a replacement model, they are also compatible with some multiregional models. The concluding chapter makes the case that modern human origins are mostly, but not exclusively, out of Africa.

While those who study human origins now agree that the evolution of modern human form extends back much further in time than the evolution of modern human behavior, they disagree sharply as to how to interpret the substantive data. Two fundamentally incommensurate interpretations of our origins, the "Replacement" camp and the "Continuity" camp, have now emerged out of pre-existing models and theories that go back to the last quarter of the 19th century. This book contends that these positions are based on radically different biases and assumptions about what the remote human past was like. The purpose of this volume is to examine those conceptual differences, not to arrive at a consensus, but rather to explore the reasons why a consensus might never be possible.

Describes how mapping the human genome has aided paleoanthropologists in their study of ancient bones used to explore human origins, from the earliest humans--bipedal apes--up to Martin Pickford's Millennium Man.

Interrogating Human Origins encourages new critical engagements with the study of human origins, broadening the range of approaches to bring in postcolonial theories, and begin to explore the decolonisation of this complex topic. The collection of chapters presented in this volume creates spaces for expansion of critical and unexpected conversations about human origins research. Authors from a variety of disciplines and research backgrounds, many of whom have strayed beyond their usual disciplinary boundaries to offer their unique perspectives, all circle around the big questions of what it means to be and become human. Embracing and encouraging diversity is a recognition of the deep complexities of human existence in the past and the present, and it is vital to critical scholarship on this topic. This book constitutes a starting point for increased interrogation of the important and wide-ranging field of research into human origins. It will be of interest to scholars across multiple disciplines, and particularly to those seeking to understand our ancient past through a more diverse lens.

This 3-volume handbook brings together contributions by the world ́s leading specialists that reflect the broad spectrum of modern palaeoanthropology, thus presenting an indispensable resource for professionals and students alike. Vol. 1 reviews principles, methods, and approaches, recounting recent advances and state-of-the-art knowledge in phylogenetic analysis, palaeoecology and evolutionary theory and philosophy. Vol. 2 examines primate origins, evolution, behaviour, and adaptive variety, emphasizing integration of fossil data with contemporary knowledge of the behaviour and ecology of living primates in natural environments. Vol. 3 deals with fossil and molecular evidence for the evolution of Homo sapiens and its fossil relatives.

This update to the award-winning The Origins of Modern Humans: A World Survey of the Fossil Evidence covers the most accepted common theories concerning the emergence of modern Homo sapiens adding fresh insight from top young scholars on the key new discoveries of the past 25 years. The Origins of Modern Humans: Biology Reconsidered allows field leaders to discuss and assess the assemblage of hominid fossil material in each region of the world during the Pleistocene epoch. It features new fossil and molecular evidence, such as the evolutionary inferences drawn from assessments of modern humans and large segments of the Neandertal genome. It also addresses the impact of digital imagery and the more sophisticated morphometrics that have entered the analytical fray since 1984. Beginning with a thoughtful introduction by the authors on modern human origins, the book offers such insightful chapter contributions as: Africa: The Cradle of Modern People Crossroads of the Old World: Late Hominin Evolution in Western Asia A River Runs through It: Modern Human Origins in East Asia Perspectives on the Origins of Modern Australians Modern Human Origins in Central Europe The Makers of the Early Upper Paleolithic in Western Eurasia Neandertal Craniofacial Growth and Development and Its Relevance for Modern Human Origins Energetics and the Origin of Modern Humans Understanding Human Cranial Variation in Light of Modern Human Origins The Relevance of Archaic Genomes to Modern Human Origins The Process of Modern Human Origins: The Evolutionary and Demographic Changes Giving Rise to Modern Humans The Paleobiology of Modern Human Emergence Elegant and thought provoking, The Origins of Modern Humans: Biology Reconsidered is an ideal read for students, grad students, and professionals in human evolution and paleoanthropology.

This volume is based on the Field Museum of Natural History Spring System atics Symposium held in Chicago on May 11, 1991. The financial support of Ray and Jean Auel and of the Field Museum is gratefully acknowledged. When we teach or write, we present only those elements that support our arguments. We avoid all weak points of our debate and all the uncer tainties of our models. Thus, we offer hypotheses as facts. Multiauthored books like ours, which simultaneously advocate and question diverse views, avoid the pitfalls and lessen the impact of indoctrination. In this volume we analyze the anthropological and biological disagreements and the positions taken on the origins of modern humans, point out difficultieswith the inter pretations, and suggest that the concept of the human origin can be explained only when we first attempt to define Homo sapiens sapiens. One of the major controversies in physical anthropology concerns the geographic origin of anatomically modern humans. It is undisputed, due to the extensive research of the Leakeys and their colleagues, that the family Hominidae originated in Africa, but the geographic origin of Homo sapiens sapiens is less concretely accepted. Two schools of thought existon this topic.
