These barriers can be split into two categories based on when they act: prezygotic and postzygotic. Speciation occurs across the range of spatial contexts summarized by the allopatric to sympatric continuum, but most speciation is associated with geographic separation. This example of sympatric speciation occurred through habitat differentiation: apple maggot flies began to prefer apple trees as host plants, whereas their ancestors used hawthorn trees. The second page shares several images depicting speciation (allopatric, sympatric, and then parapatric).

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. 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 .
