The remarkable creatures in this book are of the human variety: each chapter discusses the lives and discoveries of famous explorers, paleontologists, and scientists who have helped unlock the secrets of life, starting with Darwin and ending with advances in DNA sequencing from just a few years ago. If you were thinking it would be about evolution’s remarkable creatures you have the wrong book. Although fossils are introduced and described, they get little time in the narrative compared to the careers and exploits of their discoverers. In that sense the title is misleading, and I wondered if it was chosen by the publisher instead of the author, on the assumption that something like “Famous Paleontologists and their Discoveries” would not sell as well. If you want to know about the most important ancient creatures I would recommend Donald Prothero’s Story of the Earth in 25 Fossils or Richard Fortey’s Fossils: The History of Life.
The book is, nevertheless, well researched and adds to the reader’s understanding of the process of scientific discovery and diffusion. For instance, it is well known that Darwin withheld publication of his theory for years, until forced to move forward by Alfred Russell Wallace’s parallel discovery. Darwin knew his theory would be controversial, and his wife was a devout Christian, but this book provides another, seldom discussed reason: early publication would have been a slap in the face to his mentors, who all believed in creation by supernatural means, and in any case the scientific community, much less society at large, was not ready for it. “Charles thought it was unwise, even reckless, to publish at the time. It would have meant breaking ranks with his teachers and supporters – Lyell, Henslow, and Sedgwick – as well as the rest of the scientific establishment and would be professional suicide.” (p.53-54) Over time, however, as evidence of an ancient earth appeared in the 1840s and 50s, people became more receptive to new ideas, within limits. As the author says, “Folks were starting to get used to the idea of the earth changing; they didn’t at all like the idea of life evolving.” (p. 66)
The book moves in chronological order, and these men (and a few women) deserve to be remembered. Many of them spent years under difficult circumstances, making and reporting their discoveries. Alexander von Humboldt is covered, and Wallace, so often overshadowed by Darwin, gets the attention he deserves.
The twentieth century starts with the remarkable discoveries of Charles Walcott, who is remembered today for his discovery of the 508 million year old Burgess Shale formation while on a fossil-hunting vacation in British Columbia. However, he was also one of the most influential paleontologists of the century, and served as Secretary of the Smithsonian Institution for twenty years. There was also tragedy in his life: his first wife died in a train crash, and one of his sons, who had been active in assisting in the scientific studies, was the first American airman to die in Europe during World War One.
In terms of sheer Indiana Jones-type adventure, the best chapter in the book is probably the one about Roy Chapman Andrews, who started out as a janitor just so that he could be close to the dinosaur fossils, and ended up as one of the most renowned fossil hunters of the century. His expedition to Mongolia in 1923 discovered the first dinosaur eggs, and a further expedition in 1930 added to the finds. Mongolia was rich in fossils; in some places the ground was covered with with fragments, and a few large specimens were discovered. The book mentions in an aside that it is fortunate the discoveries were in Mongolia, not China, where for centuries fossils had been ground up as “dragon bones” and used in folk medicine. There is also a humorous incident which shows some of the hazards the expedition faced, in that one freezing night, as they slept, poisonous vipers entered their tents to warm themselves. No one was injured, but it must have been an exciting morning when they woke up.
There is also a chapter on Linus Pauling, who was a great scientist with many important discoveries to his credit. He did important work in X-ray crystallography and applying quantum mechanical calculations to atoms and molecules, and enhanced his reputation with a series of papers on chemical bonds. He was also a peace activist and opponent of nuclear weapons, who was refused a passport by the US government on the grounds that he might have had Communist sympathies. The book does not mention that he was also an avowed racist and eugenicist, and his insistence on treating his wife’s cancer with massive doses of Vitamin C instead of radiation and surgery probably shortened her life.
The book has an interesting chapter on the Leakeys and their east African discoveries of early hominids. Richard Leakey was more of an administrator than a hands-in-the-dirt paleontologist, so much of the actual work in the field was done by his wife Mary.
In bringing the reader up to the present time, the book ends with a discussion of the molecular clocks embedded in our DNA, where the rate of change can be roughly calculated, allowing researchers to estimate when any two species diverged from their last common ancestor.
Since I was expecting this book to be about fossils, not their discoverers, it was not what I had anticipated. I enjoyed it, however, and learned a number of things, and it is written in a style that is accessible to anyone.
