A population of finches on the Galapagos has been discovered in the process of becoming a new species. In 1981, researchers noticed the arrival of a male of a non-native species on a tiny Galapagos island called Daphne Major.  They noticed that this male, a large cactus finch, proceeded to mate with a female of one of the local species, a medium ground finch, producing fertile young. The researchers then followed the entire population of finches on a tiny Galapagos island called Daphne Major, for thirty-six years, and so were able to watch the speciation in progress.

Genetic analysis shows that the South Hills crossbill coevolved with the Rocky Mountain lodgepole pine, a striking example of coevolution driving speciation within perhaps as little as 6000 years.  “This is maybe the best and only clear example of reciprocal adaptation between two species contributing directly to the process of speciation”.
