What did darwin conclude about the finches on the galapagos islands that later supported his theory of evolution? check all that apply. the finches on the galapagos islands all had the same beak. the finches on the galapagos islands had different beaks. the beaks of the finches stayed the same over time. the beaks of the finches changed over time. the galapagos finches had a common ancestor. the galapagos finches did not have a common ancestor.

The finches on Galapagos Islands had different beak

The beaks of the finches changed over time

The Galapagos finches had a common ancestor

Explanation: Darwin's Finches are a good example of natural selection and adaptive radiation of evolution. The different finches in Galapagos Island have emerged from a common  black, seed eating, short beak finches. This is called adaptive radiation, where different species arose from a single ancestor.

Due to changes in the natural environment, food resources, some finches have a long beak. This long beaks help them to eat insects. As a result, the competition will be less and nature selects them to survive in the new environment. This is a natural selection of evolution.
