Darwin's finches and adaptive radiation
WebDarwin’s Finches Galapagos Islands are a chain of islands resulting from volcanic action. These islands were never connected to mainland South America. Darwin’s finches descended from small sparrow-like birds that once inhabited the mainland and migrated to Galapagos islands. WebAdaptive radiation unfolds as selection acts on the genetic variation underlying functional traits. The nature of this variation can be revealed by studying the tips of an ongoing adaptive radiation. We studied genomic variation at the tips of the Darwin's finch radiation; specifically focusing on p …
