Answer:
Charles Darwin was the man who came with the theory of natural selection. He witnessed finches within the Galapagos Islands and made notes on the similarities and differences of the finches across the group of islands. Each of the islands comprises finches, which were identical, however distinct in different ways.
Darwin found that the finches appeared to vary on the basis of the food sources available on each of the islands. If the prime food were seeds, the finches seemed to possess thicker beaks in order to break the seeds so that they can consume them.
On the other hand, if the prime food sources were insects, then the finches seemed to exhibit smaller and pointer beaks so that they could hold the insects readily. In this way, there is unity in diversity. All of these birds are finches and exhibited a common ancestor from which they have originated into the distinct species as mentioned.
Their variations lie in the habitats, in which they now inhabit. They had to amend with their environments in order to thrive, thus, offering diversity to unity.
