The flies that were born in apples tended to feed on apples and mate with other flies on apples, while the flies born on hawthorns tended to similarly stick with hawthorns, Over time, the population diverged into two genetically distinct groups with adaptations, features arising by natural selection, that were specific for apple and hawthorne fruits. Because the squirrels on the north and south sides were reproductively isolated from one another due to the deep canyon barrier, they eventually diverged into different species.

This simple worksheet helps students distinguish between allopatric and sympatric speciation. Presumably, students volition realize that allopatric relies mainly on geographic isolation, but sympatric requires other mechanisms, such equally timing, behaviors, or niche choice. The process of forming new species from a pre-existing species is called anagenesis. There are multiple ways to define the concept of "species." The choice of definition is dependent on the particularities of the species concerned. In the last section of the lesson, students explore sympatric speciation, by reading about the apple maggot fly.
