The Beak of the Finch by Jonathan Weiner is about two scientists who explore Charles Darwin's theory of evolution. The author reveals that Peter and Rosemary Grant, the scientists, believed Darwin did not fully understand the importance and relevance of his theory. The two scientists observed how natural selection applied to finches. They concluded that natural selection is continuous and always taking place.
Weiner provides an in-depth description of the processes that the two scientists went through to make their research successful. Furthermore, he interviews several biologists who focus on other animals. They collect information that Darwin did not, and they explain how the Grants motivated them to study more about evolutionary changes.
The author reveals the mystery and beauty in evolution and analyzes Judeo-Christian beliefs concerning evolution without bringing up the concept of God. He reveals interesting views about the pattern of evolution in different environments. The author also discusses the formation of species and implies that it does not occur because of geographical isolation. Furthermore, Weiner explains how hybrids are produced and the role they play in the formation of species.
