Parapatric vs peripatric speciation
WebSpeciation is the process by which new species form. It occurs when groups in a species become reproductively isolated and diverge. In allopatric speciation, groups from an … Mathematical models, laboratory studies, and observational evidence supports the existence of parapatric speciation's occurrence in nature. The qualities of parapatry imply a partial extrinsic barrier during divergence; thus leading to a difficulty in determining whether this mode of speciation actually occurred, or if an alternative mode (notably, allopatric speciation) can explain the data. This problem poses the unanswered question as to its overall frequency in nature.

Allopatric, peripatric, and parapatric speciation all involve some form of geographic separation, either partial or complete. Sympatric speciation is the only type of speciation that takes place while subgroups of a species occupy the same range, and ... WebPeripatric speciation closely resembles allopatric speciation. New species arise in isolated, smaller peripheral populations that are prevented from exchanging genes with the main population. It is related to the concept of a founder effect, since small populations often undergo bottlenecks.
WebMay 24, 2024 · Parapatric speciation is a mode of speciation in which there is no extrinsic barrier between the population but, the large geographic range of the population causes the individuals to mate with the neighboring individuals than with the individuals in a different part of the geographical range.
