“The Beak of the Finch” is an autobiographical book that talks about the author’s time exploring the finches on Galápagos together with a scientist couple, Peter and Rosemary Grant. The reason for the observation of the finches is because of their importance in the Darwin’s theory of evolution. Their example shows how evolution is something observable, happening day by day, especially with the evidence of their beaks and how they evolved.
The author continues to explain the background of this change, how the finches of the Galápagos changed in their appearance over the years, conditioned by food, weather and other factors. Further, in the book, the author explains how these factors influence the evolution of finches in particular. He explains how the mating process, the selection of mates between different species of finches, creates new ones. In the next part of the book, the author brings in the human factor in the evolutionary process. He explains the responsibilities and dangers of human’s ability to influence the evolution.
The author concludes the novel by contemplating the evidence of how the nature is constantly evolving to fight back the human influence, giving various examples. He urges the importance of information to the evolutionary process, and how the sharing of the information is crucial for the continuation of it.
