Some of its most exciting insights have come from the crossover of disciplines as As I teach my unit on "Population Genetics", I assign a portion of these questions for homework each night. However, it is more common for the process to be extended over many generations (up to millions; Coyne & Orr 1997, 2004).The process is continuous, but it may be helpful to ask what initiates the evolution of intrinsic reproduction isolation, what causes isolation to increase (in terms of both .
