The lesson explores the two models of speciation: allopatric and sympatric. Speciation is when individuals within a population undergo change to such a degree that they become a new and distinct species. This most often occurs due to geographic isolation or reproductive isolation of individuals within the population. Define speciation. At this point, the groups can be considered separate species. These mechanisms can lead to each subpopulation becoming so different, that they can no longer interbreed and are considered separate species.
