In the Galapagos Islands, Charles Darwin found many different species of finches (a type of bird) that seemed closely related. H
e proposed that the birds had all evolved from a common ancestor. Match the bird beaks below to the most likely food source. Explain in the chart below how the five finches pictured above most likely came to have different beaks than each other and the extinct finch.
Why?: " Vestigial organs are physical structures that were fully developed
and functional in an ancestral group of organisms but are reduced
and unused in the later species."
