Discusses the collection, interpretation and analysis of population genetic data. Among the topics included in the text are studies on human evolutionary history, molecular techniques for generating data, statistical and computational techniques for the interpretation of such data, and stochastic models for geneology and population structure. The chapters reflect the close interaction between experimental molecular biologists and theoreticians. The text should be of interest to specialists in the area as well as mathematicians, statisticians, computer scientists and biologists wanting a brief overview of current problems in the field.
