Question
Explain how Darwin's theory of evolution by natural selection and isolation could account fo
the evolution of these finches from a common ancestor.
Answer
Darwin's theory of evolution by natural selection and isolation states that over time, populations of a species that are isolated from each other will experience different environmental pressures, leading to the development of different traits that are beneficial to survival in that environment. This process of natural selection can lead to the evolution of different species from a common ancestor. In the case of the finches, the different environmental pressures on the isolated populations led to the development of different traits, resulting in the evolution of different species from a common ancestor.
