A real find for evo- wonks: a likely case of sympatric speciation in finches.

“Examples of sympatric speciation in nature are rare and hotly debated. We describe the parallel speciation of finches on two small islands in the Tristan da Cunha archipelago in the South Atlantic Ocean.”

For a fascinating book on the subject– by a scientist who allegedly convinced evo- maven Enst Mayr that sympatric speciation, the splitting of a population into two species in one place, was possible– see menno Schilthuizen’s Frogs, Flies, and Dandelions: The Making of Species
