Essay

This chapter discussed speciation by genetic divergence following geographic isolation,which is expected to lead to reduced gene flow,a process known as allopatric speciation.A more controversial form of speciation is the genetic divergence of populations without physical isolation,a process known as sympatric speciation.Can you envision a mechanism or process that would permit two coexisting populations of the same species to begin to diverge without being isolated from one another?
