Finches (Darwin's Finches)

Darwin's finches are a group of bird species from the Galápagos Islands that were studied by Charles Darwin in the 1830s. They are notable for their diverse beak shapes and sizes, which evolved to adapt to different food sources, such as seeds, insects, and flowers. This variation is a prime example of natural selection, illustrating how species can change over time based on environmental pressures. The finches provided crucial evidence for Darwin's theory of evolution, showing how isolation and differing habitats can lead to the development of new traits and species.
