PDF 16-3 The Process of Speciation 2019-04-03T12:07:36-07:00 A critical requirement for speciation to occur through hybridization of two distinct species is that the new lineage must be ecologically competitive that is, good at competing for food and other resources with the other species and this has been the case for the Big Bird lineage.

On Nov. 23 in the journal Science, researchers from Princeton University and Uppsala University in Sweden report that the newcomer belonging to one species mated with a member of another species resident on the island, giving rise to a new species that today consists of roughly 30 individuals. And Darwin's finches are ideal subjects for field research in evolutionary biology. The study tracked Darwin's finches on the Galpagos island of Daphne Major, where a member of the G. conirostris species (pictured) arrived from a distant island and mated with a resident finch of the species G. fortis.
