About the Author

Jody Hey is Professor of Genetics at Rutgers University, where he uses both mathematical theory and DNA sequencing to study the process of evolution. In recent years he has conducted research on the evolutionary divergence of fruit fly species and on the evolutionary origins of modern humans. This book was written while Dr. Hey was visiting the University of Edinburgh, Scotland with the aid of a John Simon Guggenheim Fellowship.

Reviews

"His casual style and thought-provoking examples are convincing...Combining the data collection Hey calls for with a treatment of species concepts as models would advance our understanding of how the world of real evolutionary groups is structured." -- Kerry L. Shaw, Science
"In this important and refreshing view of the species debate, Jody Hey draws on a range of philosophical and evolutionary arguments to argue convincingly . . ."--Heredity
"This book links together philosophy, linguistics, and biology in an innovative fashion to arrive at a resolution of the long-standing "species question" of biology. Hey is able to frame his arguments in a style that makes what might otherwise be impenetrable, engaging. It will stimulate useful discussion and insight into the history of science, the physics-envy of ecologists, and the ability of scientists to be truly objective. A thought-provoking and
profoundly insightful work."--Choice
