Charles Darwin's finding that the finches on the Galapagos islands looked different from the mainland finches despite their common ancestry from South America is an example of C. adaptive radiation.
Common ancestry refers to blood relationships. Thus, two species may have common ancestry if they are related by blood.
According to Charles Darwin, common ancestry explains the similarities between different species.
However, a rapid increase in the number of species with a common ancestor, characterized by great ecological and morphological diversity results from adaptive radiation.
Thus, Charles Darwin's finding that the finches on the Galapagos islands looked different from the mainland finches despite their common ancestry from South America is an example of C. adaptive radiation.
