The color of the bottom beak in the fifth generation offspring of the immigrant is orange while the native G. fortis resident's beak is fully black. This caused an increase in the finches' average beak size between 1976 and 1978. This island is large enough to support good-sized finch populations, yet small . It is likely that new lineages like the Big Birds have originated many times during the evolution of Darwins finches, according to the authors. No claim t\ o original U.S. Government Works.

What forced brother and sister mating in the birds? So, in 1981, when a member of their research team noticed a young male with an imposing beak and a strange song, the Princeton population or group of populations whose members can interbreed and produce fertile offspring.

The breeding of two distinct parent species gave rise to a new lineage (termed "Big Bird" by the researchers). Good thing these are birds. In endogamy, the goal is always to reproduce with gametes of similar ancestry so closely related individuals of the same species would prefer to mate with each other.
