Answer:
The study of the Galapagos finches provided important evidence to support Charles Darwin's Natural Selection hypothesis in the 19th century. Darwin realized that the several species of finches distributed throughout the Galapagos archipelago had different beaks, which varied according to the eating habits of each species. However, despite these differences in beaks, the various finch species have other characteristics very similar to each other, such as reproductive traits. By observing these species, Darwin was able to postulate that they were all derived from the same common ancestor, and that species differentiation must have occurred due to the action of evolutionary factors such as geographic isolation of island populations, competition and differences in ecological environments. The different finches' beaks became a classic example of biological adaptation due to the action of these evolutionary factors.
