Determine the type of speciation described in each paragraph. Two populations exist in the same geographic area. Differences in behavior or choice of ecological niche separate the populations. Once enough genetic differences accumulate between the populations, they no longer interbreed and are two distinct species. Some species exist over large geographic ranges. The populations found at the extreme ends of the range can develop enough genetic or behavioral differences that they are no longer able to interbreed if brought together. The populations at the ends of the range are separate species. A geographic barrier separates two populations. When the geographic populations are reunited, they no longer interbreed and are unique species.

Two populations exist in the same geographic area.
Differences in behavior or choice of ecological niche
separate the populations. Once enough genetic differences
accumulate between the populations, they no longer
interbreed and are two distinct species.
Some species exist over large geographic ranges. The
populations found at the extreme ends of the range can
develop enough genetic or behavioral differences that they
are no longer able to interbreed if brought together. The
populations at the ends of the range are separate species.
A geographic barrier separates two populations. When the
geographic populations are reunited, they no longer
interbreed and are unique species.
