In Science this week, a team of Swedish and US scientists present a genomic analysis of species of finches from the Galapagos Islands, identifying the genetic locus associated with the differences in sizes observed by Charles Darwin, contributing to his principle of character divergence — a process of morphological divergence that reduces competition for limited resources. The researchers sequenced the genomes of six species of Darwin's finches that differ in size and related traits.
