Quote:A population of finches on the Galapagos Islands has been “caught in the act” of becoming a new species, according to the journal Science.

It reports that researchers saw the finches mixing with other birds to create a third species, in what is thought to be the first example of speciation observed directly in the field.

Darwin finches, such an apt name.

Quote:Homoploid hybrid speciation in animals has been inferred frequently from patterns of variation, but few examples have withstood critical scrutiny. Here we report a directly documented example from its origin to reproductive isolation. An immigrant Darwin’s finch to Daphne Major in the Galápagos archipelago initiated a new genetic lineage by breeding with a resident finch (Geospiza fortis). Genome sequencing of the immigrant identified it as a G. conirostris male that originated on Española >100km from Daphne. From the second generation onwards the lineage bred endogamously, and despite intense inbreeding, was ecologically successful and showed transgressive segregation of bill morphology. This example shows that reproductive isolation, which typically develops over hundreds of generations, can be established in only three.
Creationist on this site will likely whine "but it's still  finch " or "that's just micro evolution" excuses excuse
