Finches on the Galapagos islands exhibit remarkable variation in the shape of their beaks. What best explains this variation?Multiple choice question.Differences in their feeding habitsSubtle differences in the climate of different Galapagos islandsDifferences in their predatorsDifferences in their breeding strategies

How did natural selection shape the evolution of finches on the Galápagos Islands?Multiple choice question.Several different bird species migrated from the mainland to the Galápagos Islands and occupied the habitats to which they were best suited.Birds that used their beaks to crack bigger seeds acquired larger beaks in their lifetime and passed this trait on to their offspring.Birds with different heritable differences were able to better survive and reproduce in different habitats.

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.

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

What did Darwin observe about the finches he collected from the Galápagos Islands?a. They all had identical beak shapesb. They were unrelated to each otherc. They evolved from South American speciesd. They had different beak shapes suited to their diet
