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

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 were found on an island but not on the mainland.Because they all looked nearly identical.Because they had the same beaks regardless of their food source.

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.

Charles Darwin observed several species of finches on the Galápagos Islands, each with distinct beak shapes and sizes. These differences appeared to be adaptations to the specific types of food available on each island. For example, finches on islands with abundant hard seeds had stronger, thicker beaks, while those on islands with insects had thinner, sharper beaks.Which of the following observations by Darwin most directly led to his theory of natural selection?Question 2Answera.Variation in Traitsb.Adaptation to the Environmentc.Overproduction of Offspringd.Inheritance of Traits
