How could a randomly mating population reduce gene flow and speciate? Merely exploiting a new niche may automatically reduce gene flow with individuals exploiting the other niche. This may occasionally … WebA model proposing that speciation occurs in small populations isolated on the periphery of the distribution of the parental population, as opposed to parapatric speciation (q.v.).

"Peripatric speciation models are identical to models of vicariance (allopatric speciation). Requiring both geographic separation and time, speciation can result as a predictable byproduct. Peripatry can be distinguished from allopatric speciation by three key features: • The size of the isolated population " - Effects of peripatric speciation
