This bundle is zero prep and maximum engagement. Speciation occurs across the range of spatial contexts summarized by the allopatric to sympatric continuum, but most speciation is associated with geographic separation. An introduction to evolution: what is evolution and how does it work? Suppose that two groups of animals are reproductively separated due to a mechanical barrier, but if we artificially fuse their gametes and implant the resultant zygote in a female womb, the zygote can develop into a healthy fertile organism. This method works well when the species in question look very different from one another. They read short scenarios and identify what types of isolating mechanisms are being described. In the last section of the lesson, students explore sympatric speciation, by reading about the apple maggot fly.

These two groups do not interbreed. Students would write that this type of speciation is allopatric speciation with geographic isolation. . Pre-made digital activities. Then, students simulate speciation within a hypothetical population of frogs, using manipulatives to create a model. (b) Modern elephants evolved from the Palaeomastodon, a species that lived in Egypt 35-50 million years ago. In general, animal species are much less likely to tolerate changes in ploidy. Because members of a species can interbreed, the species as a whole has a common. It's fun and almost no prep! Finally, students answer post-activity questions.A. We're sorry, some parts of the bnbfinder website don't work properly without JavaScript enabled. However, many scientists think this is a case of sympatric speciation in progress.

For speciation to occur, two new populations must be formed from one original population, and they must evolve in such a way that it becomes impossible for individuals from the two new populations to interbreed. The lesson explores the two models of speciation: allopatric and sympatric.
