Why are finches in the Gal and aacutepagos Islands a good example of speciation?
Asked in Biology, Charles Darwin
What adaptations did Darwin notice in finches?
He noticed that birds called finches had different kinds of beaks in areas with different food sources. He found finches with thick beaks in areas with large hard shelled nuts, and finches with smaller beaks in areas where fruits were available. These differences seemed to match the environment and the diet of the finches.

WHAT SPECIFIC DIFFERENCES ABOUT THE FINCHES ON THE GALAPAGOS ISLANDS WERE OF GREAT INTEREST TO DERWIN?
Asked in Biology
What are some adaptations found among the finches of the Galapagos?
Galapagos finches, also known as Darwin's finches, are only found on the Galapagos islands in the Pacific. They were first recorded by Charles Darwin and his observations of the birds helped him with his theories on evolution. The specific adaptation he noted in the finches was that one group whose food source was hard nuts had sharp beaks. Another group whose food was fruit had smaller beaks. These observations led him to the belief that the birds had evolved different characteristics to match their food sources.
Asked in Galapagos Islands
How did the galapagos finches evolve?
It is believed that a few seed-eating finches were blown from South America to the Galapagos Islands many years ago. These finches breed and reproduce over time, and they flew to different islands. The descendants of the original finches would show variation in the shapes of sizes of their beaks, which enable them to find a particular food source better, such as seeds, fruits and insects. Individuals with beaks that helped to find food survived and reproduced more offspring. Eventually, finches with beaks this shape would replace those that were not as well adapted to the environment and a new species of finches would gradually evolve.
