Meanwhile, neighboring grasses don't live in polluted soil, but they occupy a continuous geographic population. River otters that live in South American rivers eat fish and other smaller creatures they can capture. It seems In Evolution in Action: Isolation and Speciation in the Lower Congo River, a team of scientists, including ichthyologists, geographers, and hydrologists, investigate the Lower Congo River to learn why it supports such amazing biological diversity.. These animals have become reproductively isolated from the closely related sea otter, who live in the ocean waters along the Pacific coast, many thousands of miles away. This beautiful cartoon provides a great way to introduce topics such as allopatric speciation and adaptive radiation. D. Adaptive Radiation. Define speciation. Allopatric Speciation 1. Divergent Speciation occurs when species form, existing at the same time, likely in different locations 4. Worksheets (Opening image copyright Daniel Korzeniewski, 2010. This doesn't have to be used as a guided notes worksheet because the questions are thought-provoking and applicable to any biology class that is learning about the origin of species. Allopatric speciation • Allopatry: not in the same place –Divergence occurs in geographically separated groups • Some physical barrier to migration of alleles from one population to another • Initial separation of populations could be –Dispersal –vicariance. The two grasses have evolved different flowering times (niche). Allopatric speciation can occur even if the barrier is a little "porous," that is, even if a few individuals can cross the barrier to mate with members of the other group. The process of allopatric speciation begins when populations become geographically isolated, preventing mating between individuals in different populations and thus stopping gene flow.
