Peter Grant is the emeritus Class of 1877 Professor of Zoology and an emeritus professor of ecology and evolutionary biology, and Rosemary Grant is an emeritus senior research biologist. 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. 1.

Thus, different beak sizes will be favored at different times. During some years, selection will favour those birds with larger beaks.

The arrival of human beings means a new phase in the evolution of Darwin's finches, and its directions are still unclear. [6] They compared the differences of bill length to body size between populations living on the Islands and the nearby mainland. A team of scientists from Princeton University and Uppsala University detail their findings of how gene flow between two species of Darwins finches has affected their beak morphology in the May 4 issue of the journal Nature Ecology and Evolution. Darwin made his discovery with the finches, two scientists, Peter and Rosemary Grant, returned to the Galpagos to take a closer look at the finches. They have worked to show that natural selection can be seen within a single lifetime, or even within a couple of years.

The finches that Peter and Rosemary Grant chose to study the Finches in the Galapagos because they are hybrid. endobj Genes for beak shape (ALX1) and beak size (HMGA2) have been determined to be crucial in separating the hybridized species from local finches. [10] The lack of rain caused major food sources to become scarce, causing the need to find alternative food sources. Furthermore, hybrid females receive their Z chromosome from their cactus finch father and their W chromosome from their ground finch mother.
