Galapagos Finches: Darwin's Living Laboratory | Vibepedia

Galapagos finches, a group of about 15 species of passerine birds, are famously known for their remarkable diversity in beak shape and size, a direct result of adaptive radiation. These small, unassuming birds, primarily found on the Galapagos Islands, became the cornerstone of Charles Darwin's theory of evolution by natural selection after his visit in 1835. Each finch species evolved specialized beaks to exploit different food sources available on the islands, from crushing seeds to probing for insects. Studying their ongoing evolutionary changes, particularly in response to environmental shifts like El Niño events, continues to provide invaluable insights into the mechanisms of speciation and adaptation.
