Evolution in Action Through Photography

Photographs from the Galápagos Islands highlight Darwin's finches, illustrating their evolutionary adaptations. These birds, descended from a single ancestor, developed diverse bill shapes to exploit different food sources, a process of adaptive radiation. Notably, the Woodpecker Finch uses tools like cactus spines to find insects, and the Vampire Ground-Finch feeds on the blood of other birds. Studies by Peter and Rosemary Grant documented rapid evolutionary changes in finch populations, demonstrating that evolution can occur quickly under specific environmental conditions.
