As evolutionary biologists we seek to understand the fundamental principles that explain how change occurs in life over the course of time. Speciation, one of the cornerstones of Darwinian theory, is the process whereby one gene pool is divided into two. Our research elucidates sympatric speciation or the dividing of gene pools in the absence of geographic or physical isolation, and in the face of gene flow. We use a multidisciplinary research strategy that utilizes molecular biology, field ecology, and population genetics to address the question of how two populations of a species develop into two distinct species.
