Speciation is the process by which new species evolve from existing species through the accumulation of genetic and phenotypic differences over time. 4.

WebIn peripatric speciation, small population size would make full-blown speciation a more likely result of the geographic isolation because genetic drift acts more quickly in small populations. Genetic drift, and perhaps strong selective pressures, would cause rapid genetic change in the small population. This genetic change could lead to speciation.
