Most of us were taught in school that the bedrock of Darwin's book
Origin of the Species and his theory of adaptation stemmed from his observation of finches in the Galapagos Islands. While on Galapagos, he collected and categorized finches from every island he visited, mostly as a study of
what exists, but not
why they exist.

It was only after he returned home to England and began studying his samples that he came to the realization that the birds from each island had developed slightly differently. Specifically, depending upon where they lived and the type of vegetation that was available on their particular island, they had developed unique beak styles that provided the best and most efficient access to their food source.
