Speciation is a slow process due to which populations evolve into different species. Students first read about allopatric speciation and apply it to the finches on the Galapagos islands. Boggs, in International Encyclopedia of the Social & Behavioral Sciences, 2001 3.2 Parapatric Speciation 'Parapatric' derives from 'para' meaning 'near' and 'patria' meaning 'country.'

These two groups do not interbreed. Students would write that this type of speciation is allopatric speciation with geographic isolation. How new species can arise from existing species. Two species might prefer different habitats and thus be unlikely to encounter one another. A mule is the hybrid offspring of a female horse and male donkey. But when we get right down to it, what really make a species a species? 14.
