On Methuselah's Trail tells the story of some of the Earth's most remarkable inhabitants living fossils. Labelled 'living fossils' by Darwin, the ancient animals and plants Peter Ward explores have survived with little or no change the cataclysmic events that transformed life on earth. These 'Methuselahs' can tell us much about the history of life and about the great extinction periods in which so many other species died out. Não foram encontradas descrições de bibliotecas. |

Ward's specialty is the nautilus, and his book is most fascinating when he is discussing the differences between the ammonites (a species similar to the nautilus, but which specialized in response to environmental and predatory changes and which, despite flourishing during several epochs, became extinct. Ward takes us on location to various parts of the world in search of fossil evidence. His enthusiasm and fascination for pieces of rock is almost enough to cause you to resign from your job and switch to geology as a new career.
"Paleontologists live like that in some sense; their physical lives run along in simple, linear track of time, but their minds move back and forth through the ages, jumping onto the tracks where time moves at a more complicated pace. Perhaps we are searching for the lessons of our own survival, chasing clues by studying the lives of the Methuselahs." ( )
