The ability to use DNA evidence is revolutionizing our understanding of the past. This book introduces archaeologists to the basics of DNA research so they can understand the powers and pitfalls of using DNA data in archaeological analysis and interpretation. By concentrating on the principles and applications of DNA specific to archaeology, the authors allow archaeologists to collect DNA samples properly and interpret the laboratory results with greater confidence. Written by archaeologists who conduct fieldwork as well as laboratory analysis, the volume is replete with case examples of DNA work in a variety of archaeological contexts and is an ideal teaching tool for archaeologists and their students.
