Parapatric speciation has no specific extrinsic barrier to gene flow. The population is continuous, but the population does not mate randomly. Individuals are more likely to mate with their geographic neighbors than with individuals in a different part of the population’s range. In this mode, divergence may happen because of reduced gene flow within the population and varying selection pressures across the population’s range.
