Peter went first in March 1973 with the Abbots and banded about 60 or 70 medium ground finches . For the Grants, evolution isn't a theoretical abstraction. They have demonstrated how very rapid changes in body and beak size in response to changes in the food supply are driven by natural selection. The grants have studied the effects of drought and periods of plenty on the finches, and the results of. 3 What was the major claim Peter and Rosemary Grant concluded as a result of their research in the Galapagos Islands? Long beaked finches survived because their food/supply was not affected, the next time the Grants flew in, there was an INCREASE in the large beak phenotype.

[2] The Balzan Prize citation states: The Grants are both Fellows of the Royal Society, Peter in 1987, and Rosemary in 2007. This is especially true for, let's say, the wing span of the bird or the shape of the beak or the strength of the flying abilities of the bird. Lastly, and as the author states, most importantly, selection can change over time. Rosemary and Peter Grant of Princeton University, co-authors of the new study, studied populations of Darwins finches on the small island of Daphne Major for 40 consecutive years and observed occasional hybridization between two distinct species, the common cactus finch and the medium ground finch.

We provide evidence of a substantial gene flow, in particular from the medium ground finch to the common cactus finch., A surprising finding was that the observed gene flow was substantial on most autosomal chromosomes but negligible on the Z chromosome, one of the sex chromosomes, said Fan Han, a graduate student at Uppsala University, who analysed these data as part of her Ph.D. thesis. [9] There are thirteen species of finch that live on the island; five of these are tree finch, one warbler finch, one vegetarian finch, and six species of ground finch.
