Galapagos finches
Galápagos finches are a group of bird species native to the Galápagos Islands, famous for their role in studying evolution. They have diverse beak shapes and sizes adapted to different diets, such as seeds, insects, or nectar. These variations arose due to natural selection, where finches with advantageous traits for their environment survived and reproduced. Over time, this led to new species with distinct features. Their diversity provides valuable insight into how species evolve in response to environmental changes, making them a key example of adaptive radiation in biology.
