Summary
When isolated populations (north, south) of the green-eyed tree frog met again 8,000 years ago, each had changed in subtle ways. The calls of the male frogs were different, and more importantly, the offspring of a north-south pairing didn't survive well. One population that was cut off from its southern kin (isolated south) found a way to ensure healthy young. Isolated southern females selected southern males by virture of their distinctive call. The preference resulted in rapid speciation between the two populations of southern frogs.
