Many ancient diseases with a long history of afflicting mankind such as Tuberculosis and Malaria are now re-emerging. Greenblatt brings together palaeopathologists, anthropologists, molecular biologists and modern infectious disease specialists to examine this phenomenon. New techniques allow us to detect ancient pathogen DNA and other biomarkers, in effect the chemical 'signatures' of pathogens. These tools could help us develop strategies to combat modern emerging diseases. This book focuses on ancient diseases in order to bridge the gap that has for so long separated today's infectious disease specialists and the paleopathologists who describe pathology in skeletal and mummified remains. Linking these two research communities, and incorporating the views of anthropologists, medical ecologists and molecular/evolutionary biologists, will hopefully promote a better understanding of this complex but vitally important field. A more thorough knowledge of the impact of evolutionary biology on the host-parasite relationship may even enable us to coexist with these pathogenic micro-organisms. The book is intended to stimulate debate and co-operation between infectious disease specialists, medical researchers, archaeologists, anthropologists and evolutionary biologists.
