According to Darwin, the 14 species of finches on the Galapagos Islands resemble each other and the finches along the coast of the South American mainland due to which of the following?Multiple choice question.The finches all have a similar diet.The finches are descended from a relatively recent (several million years) common ancestor.The finches have independently evolved similar characteristics.The climate on the Galapagos Islands is similar to the climate on the South American mainland.

How did natural selection shape the evolution of finches on the Galápagos Islands?

Why did Darwin infer that finches on Galápagos islands had undergone evolution by natural selection?Multiple choice question.Because of the close correspondence between their beaks and their food.Because they all looked nearly identical.Because they were found on an island but not on the mainland.Because they had the same beaks regardless of their food source.
