Common Cactus Finch |
||||||
 |
||||||
|
||||||
| British scientist Charles Darwin’s studies of finches in the Galápagos Islands laid the groundwork for his theory of natural selection. His finding that each island was home to a similar yet distinct species of finch helped convince him of the gradual nature of evolution. Shown here is the common cactus finch of Santa Fe Island, Galápagos Islands. | ||||||
