On the other hand, European honeybees (A. mellifera ligustica), which are a related but
allopatric species and were introduced to Japan in the Meiji era (about 140 years ago) for apiculture, exhibit only stinging behavior against the hornet.
Our data illustrate that fitness can decline quickly in nature when previously
allopatric species interbreed.

Because neither
allopatric nor sympatric speciation require the extinction of the parent
species.
There are three main ideas concerning the emergence of new
species (Modes of Speciation), each based on the degree to which populations undergoing this process are geographically isolated from one another (
allopatric speciation, sympatric speciation, parapatric speciation).
Allopatric speciation holds that
species with large central populations are stabilized by their large volume and the process gene flow.
Comparisons of modern habitat and range of
species to late Pleistocene and Holocene assemblages and distributions reveal disharmonious associations (i.e., the occurrence of presently
allopatric taxa that are presumed to be ecologically incompatible), especially in late Pleistocene assemblages.
