Webof reproductive isolation is a fragile process that can only proceed if geographical separation renders gene flow impossible, firmly establishing allopatric speciation as the norm. Theodosius Dobzhansky (7) identified a wide array of traits that could cause reproductive isolation, but focused much of his own research into WebIn general, selection for specialization would have to be extremely strong in order to cause the population to diverge. This is because the gene flow operating in a randomly-mating population would tend to break down differences between the incipient species.
