Full disclosure: Charles Darwin is my favorite historical figure. Learning about evolution (finally) as a freshman in college and reading from On the Origin of Species exposed me to an aspect of science that was severely lacking in my earlier education and made it clear to me that there was no place for a higher power or supernatural explanations in the natural world. It is shocking that in America, that the acceptance of evolution is so low, amongst the lowest of the industrialized nations, in fact (this is addressed in the introduction). The grip of religiosity has a strong grip on it's populace, and keeps many from even questioning the myths which they learned as children.
I would recommend this book to anyone remotely interested in Darwin's life and the origins of his grand theory. It is a short read, and really well written by David Quammen. I'll be checking out more of his work. The actual story is only 253 pages long (in the hardcover I read) with the rest of the book consisting of extensive source notes and bibliography, along with acknowledgements and an index.
The book takes up just as Darwin is returning from his famous voyage to the Galapagos Islands. It describes his relationships with other great English scientists of the day, his family life, his personal interests, and ultimately, his struggle to put together his grand idea.
Darwin's family life was very interesting. He married his first cousin (common in the day), Emma, and they had ten children. Three of them died before Charles. Emma was a Christian to her death, which resulted in friction as Charles was a non-believer, and ultimately riled her ilk with his theory. But they had a successful, loving marriage, and she played a big part nursing Charles through his recurring illnesses. The story of his proposal is rather amusing.
The main drama in Darwin's story is the race to publish his grand idea. He had collected his data, consulted with other scientists, put it all together in his head, but waited ~20 years to put pen to paper. In the meantime another scientist, Alfred Wallace, was formulating ideas similar to those of Darwin. Darwin took this time off to study barnacles! Darwin published and his work and the rest is history.
Darwin's theory was controversial at the time (and still is with some) but it has since been proven true by discoveries in embryology, molecular biology, genetics, DNA, and in a number of other areas of science. He was given a hero's burial at Westminster Abbey, not far from Isaac Newton. Like the author stated, "Darwin continued the revolution Copernicus began, alerting humans to the fact that we don't occupy the central position in the universe. Darwin extended that recognition from cosmology to biology." He was one of the greatest scientists to ever live. It is worth the effort to pick up this book and learn his story in well written and concise book.
