Presumably, students will realize that allopatric relies mainly on geographic isolation, but sympatric requires other mechanisms, such as timing, behaviors, or niche choice. However, it is more common for the process to be extended over many generations (up to millions; Coyne & Orr 1997, 2004).The process is continuous, but it may be helpful to ask what initiates the evolution of intrinsic reproduction isolation, what causes isolation to increase (in terms of both . Theres some debate about how important or common a mechanism it is, but the answer appears to be yes, at least in some cases.

In some cases, there may be selection for reproductive isolationthat is, to TABle 18.1 Modes of speciation I. In allopatric speciation, groups from an ancestral population evolve into separate species due to a period of geographical separation. It was only when European settlers introduced apple trees about 200 years ago that some flies in the population started to exploit apples as a food source instead. 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. Speciation is the process by which new species form. They will read about finches, boobies, and tortoises. Reproductive isolating mechanisms preclude different species from breeding and can pb to the development of a new species. Interested in an entire Evolution unit?

This is known as, Two species might have bodies or reproductive structures that simply don't fit together. For instance, sympatric speciation may take place when subgroups in a population use different habitats or resources, even though those habitats or resources are in the same geographical area. Most of the scenarios are based on real life examples, such as lunar moths and Kaibab squirrels. 2) Form multiple evolutionary hypotheses to explain the patterns they observe.
