Abstract: On the origin of a species The formation of species remains a fascinating puzzle for the evolutionary biologist. One widely accepted mechanism, allopatric speciation, involves geographic isolation as a precursor to speciation due to divergence between the separated populations. Speciation without geographic separation requires the direct action of natural selection to complete speciation by strengthening behavioural differences, a process called reinforcement. That was the theory at least, and now speciation by reinforcement has been demonstrated in the wild, in a population of the green-eyed tree frog common in the wet tropical forests of Queensland, Australia. Further, this speciation by reinforcement has also resulted in rapid allopatric speciation.
