Is life a purely physical process? What is human nature? Which of our traits is essential to us? In this volume, Daniel McShea and Alex Rosenberg ? a biologist and a philosopher, respectively ? join forces to create a new gateway to the philosophy of biology; making the major issues accessible and relevant to biologists and philosophers alike.Exploring concepts such as supervenience; the controversies about genocentrism and genetic determinism; and the debate about major transitions central to contemporary thinking about macroevolution; the authors lay out the broad terms in which we should assess the impact of biology on human capacities, social institutions and ethical values.
