The Tree of Life: A Book Depicting the Life of Charles Darwin: Naturalist, Geologist & Thinker

The Tree of Life is organized chronologically, beginning with Darwin's birth into a prosperous English family in 1809. Because the author is tracing the influences on the young Darwin, both familial and cultural, however, the amount of information pertinent to the story could be overwhelming. Sis has developed a signature style perfectly suited to such a challenge. The illustrations are packed with pictures of people important to the story, with relevant scenes, and with additional writing that helps illuminate the story. Underneath the illustrations text runs in two and sometimes three fonts so that the reader can trace Charles Darwin's public life, private life, and what the author calls, secret life. The secret life in Darwin's case was the development of his revolutionary theory of evolution, work to which only a select few were privy.

Although in picture book format, this is not an easy book, but for children (and adults) willing to make the effort, it is deeply rewarding. One is left with a clear sense of the personal life of this famous man, from the difficulties that he had convincing his more conventional father to allow him to pursue his professional passion to his full family life with a wife and 10 children. The reader also gains a grasp of the essential aspects of his thinking about the evolutionary process.
