There are several ways that sympatric speciation can happen. Each student (or group) will create multiple species that have evolved together in the same environment and therefore contain structure that are evident of convergent evolution, divergent evolution, and coevolution. A chart in the worksheet is completed by clicking through the slides and summarizing the examples. This is a fun, easy, low-prep activity that allows students to experience the process of evolution (speciation) due to random mutation and geographic isolation. For instance, if one group evolves large body size and the other evolves small body size, the organisms may not be physically able to matea prezygotic barrierif the populations are reunited. The definition of "species" is hotly debated among evolutionary biologists and none of the (numerous) proposed definitions seems to adequately cover all cases. For example, members of a mainland population may become isolated on an island if they float over on a piece of debris. Grades: 9 th - 12 th. Speciation Round 1: 1.
