Charles darwin study of finches
WebCharles Darwin’s observations on the Galapagos Finches led to the formulation of his theory of evolution by natural selection. Darwin observed that the different finch species on the Galapagos Islands each had unique beak shapes. He noticed that their beak shapes were suited to the food available in their habitat. A long-term study carried out for more than 40 years by the Princeton University researchers Peter and Rosemary Grant has documented evolutionary changes in beak size affected by El Niño/La Niña cycles in the Pacific. Developmental research in 2004 found that bone morphogenetic protein 4 (BMP4), and its differential expression during development, resulted in variation of beak size and shape among …
