The finches on this volcanic island eat, seeds by cracking them open with their beaks. Our data show that the fitness of the hybrids between the two species is highly dependent on environmental conditions which affect food abundance that is, to what extent hybrids, with their combination of gene variants from both species, can successfully compete for food and territory, said Leif Andersson of Uppsala University and Texas A&M University. This was, probably, the first such documentation of character displacement in the wild. [20] The Grants also state that these changes in morphology and phenotypes could not have been predicted at the beginning.
