The Beak of the Finch by Jonathan Weiner is about two scientists who spent two decades analyzing the theory of evolution by Darwin. The author is an American science writer. He attempts to show the reader the contributions made by Peter and Rosemary Grant in understanding evolution, as well as their own discoveries. One of the main themes in the book is evolution. Weiner implies that evolution is an ongoing process in living things and is largely dependent on the environment. The author notes,

We see nothing of these slow changes in progress, until the hand of time has marked the lapse of ages, and then so imperfect is our view into long-past geological ages, that we only see that the forms of life are no different from what they formally were.

I enjoyed reading the book because I find evolution to be an interesting topic. I agree with the author that evolution does not occur periodically and that living things are constantly changing. Despite the book being published 24 years ago, it remains relevant today. The issues that the author addresses, such as antibiotic-resistant bacteria and global warming, continue to affect us today.
