PDF-(BOOS)-Tooth Development in Human Evolution and Bioarchaeology

Human children grow at a uniquely slow pace by comparison with other mammals When and where did this schedule evolve Have technological advances farming and cities had any effect upon it Addressing these and other key questions in palaeoanthropology and bioarchaeology Simon Hillson examines the unique role of teeth in preserving detailed microscopic records of development throughout childhood and into adulthood The text critically reviews theory assumptions methods and literature providing the dental histology background to anthropological studies of both growth rate and growth disruption Chapters also examine existing studies of growth rate in the context of human evolution and primate development more generally together with implications for life history The final chapters consider how defects in the tooth development sequence shed light on the consequences of biological and social transitions contributing to our understanding of the evolution of modern human development and cognition.

When deciduous tooth germs first differentiate, they are very small and a good deal of space is between them. This space is soon used because of the rapid growth of the tooth germs, and crowding results, especially in the incisor and canine region. This crowding is then relieved by growth of the jaws in length, which permits drifting of the tooth germs. . Animal hard material (bone, shell, ivory etc..) is also a valuable source for the combined study of technological skill of each society and the way they make use of natural resources. Finallyanimals h The core subject matter of bioarchaeology is the lives of past peoples, interpreted anthropologically. Human remains, contextualized archaeologically and historically, form the unit of study. Integrative and frequently inter-disciplinary, bioarchaeology draws methods and theoretical perspectives from across the sciences and the humanities. Bioarchaeology: The Contextual Study of Human Remains focuses upon the contemporary practice of bioarchaeology in North American contexts, its accomplishments and challenges. Appendixes, a glossary and 150 page bibliography make the volume extremely useful for research and teaching. Working with human remains raises a whole host of ethical issues, from how the remains are used to how and where they are stored. Over recent years, attitudes towards repatriation and reburial have changed considerably and there are now laws in many countries to facilitate or compel the return of remains to claimant communities. Such changes have also brought about new ways of working with and caring for human remains, while enabling their ongoing use in research projects. This has often meant a reevaluation of working practices for both the curation of remains and in providing access to them. This volume will look at the issues and difficulties inherent in holding human remains with global origins, and how diverse institutions and countries have tackled these issues. Essential reading for advanced students in biological anthropology, museum studies, archaeology and anthropology, as well as museum curators, researchers and other professionals. Human remains recovered from archaeological sites can help us interpret lifetime events such as disease, physiological stress, injury and violent death, physical activity, tooth use, diet, and demographic history of once-living populations. This is the first comprehensive synthesis of the emerging field of bioarchaeology. A central theme is the interaction between biology and behavior, underscoring the dynamic nature of skeletal and dental tissues, and the influences of environment and culture on human biological variation. It emphasizes research results and their interpretation, covering palaeopathology, physiological stress, skeletal and dental growth and structure, and the processes of aging and biodistance. It will be a unique resource for students and researchers interested in biological and physical anthropology or archaeology.
