Abstract
Evolutionary Genetics![Figure][1] Medium and large ground finches diverged in beak size after a severe drought. PHOTO: © FRANS LANTING STUDIO/ALAMY STOCK PHOTO Observations of parallel evolution in the finches of the Galapagos, including body and beak size, contributed to Darwin's theories. Lamichhaney et al. carried out whole-genome sequencing of 60 Darwin's finches. These included small, medium, and large ground finches as well as small, medium, and large tree finches. A genomic region containing the HMGA2 gene correlated strongly with beak size across different species. This locus appears to have played a role in beak diversification throughout the radiation of Darwin's finches. Science , this issue p.
