Darwins finches on the Galpagos Islands are an example of a rapid adaptive radiation in which 18 species have evolved from a common ancestral species within a period of 1 to 2 million years. We wondered whether this evolutionary change could be explained by gene flow between the two species., We have now addressed this question by sequencing groups of the two species from different time periods and with different beak morphology, said Sangeet Lamichhaney, one of the shared first authors and an associate professor at Kent State University.
