Quizplus · Accepted Answer

Sympatric speciation occurs when a single population diverges into two or more reproductively isolated groups without any physical barrier preventing gene flow. This can occur due to ecological differences or adaptation to different niches within a single geographic area. Therefore, choice E, "Divergence within a population leads to speciation in the absence of a physical barrier to gene flow," is the best definition of sympatric speciation.
