Material Detail
Connecting Concepts: Evolution/Species & Speciation 2: Patterns of Speciation
Students will think about speciation events at several points along the phylogeny of the plant genus Fuchsia. Students decide whether vicariance, dispersal, or both are plausible explanations for past and current distributions. Students will: 1) interpret phylogenies and geographical distributions to determine speciation patterns; 2) integrate understandings of continental drift with speciation; 3) analyze hypotheses as they seek to explain patterns of speciation; and 4) become familiar with the terms: allopatry, sympatry, adaptive radiation, gene flow, vicariance, and polyploidy.

Part two of three interactive exercises that investigate the how speciation occurs. Uses a specific plant species as an example. Also intoduces biogeograhy. Uses Darwins work creatively to demonstrate concepts. This concept is essential in biology. Very well written and well organized. Requires students to draw conclusions from information presennted.
Technical Remarks:
Requires Flash player
