WebExplanation: . Sympatric speciation implies a speciation event while the populations exist within the same geographical region. Animals moving around more often does not really explain why speciation would occur differently, and plants are not necessarily less prone to chromosomal abnormalities. WebThe Japanese serow (Capricornis crispus) and sika deer (Cervus nippon) in Japan are usually allopatric. However, a recent expansion in the distribution range of sika deer, combined with an increase in abundance, has resulted in an overlap of the distribution ranges of the two species.

Most new species arise in geographical isolation (allopatry) and so a key step in the assembly of communities is the geographical expansion and overlap (sympatry) of these previously spatially isolated forms [1–4].Niche assembly models predict that this build-up of sympatric diversity is a highly deterministic process [2,5].
