Charles Robert Darwin was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. He Started in South America, where he found the Galapagos islands, on each island, teh beaks of the common bird were adapted to the specific enviroments, with large, strong oned for the ones which ate other things, and small, drill-like beaks for the ones which ate seeds from fruits.
