Researchers have identified a gene in Galápagos finches studied by English naturalist Charles Darwin that influences beak shape and that played a role in the birds’ evolution from a common ancestor. The study illustrates the genetic foundation of evolution, including how genes can flow from one species to another, and how different versions of a gene within a species can contribute to the formation of new species.
