Synopsis

Where did we come from? Though researchers have done much work on this question in recent years, the answer remains elusive. In The Spark of Life , Christopher Wills and Jeffrey Bada examine the enduring mysteries surrounding life's origin: Did life arise on earth or on some other planet? What did the earliest primitive organisms look like? Were they based on RNA, DNA, or on something we would hardly recognize today? Untangling a century of contentious debate, the authors explore current theories of "the source"-from Martian meteors to hydrothermal vents-and then present their own elegant and compelling scenario: Life arose not in the subterranean depths, as many believe, but on Earth's tumultuous surface, where a primitive form of natural selection spawned the first genetic material, perhaps in the form of a proto-virus. The book ends with a whirlwind tour of one of the most exciting scientific endeavors: the search for extraterrestrial life. Knowing exactly how life began on Earth will not only teach us more about ourselves, it will bring us much closer to finding life elsewhere.

Reviews

Few scientific mysteries are as fascinating as the origin of life. Wills and Bada's book measures up to the subject's high interest. Both biologists, they ably relate the course of research since Stanley Miller and Harold Urey famously created amino acids in a test tube in 1953. The biochemistry of the primordial goo has since become better understood, as has the physical environment of the early earth. Wills and Bada's dramatic account of the forces at work during Earth's first billion years--huge tides due to the nearby moon, volcanism, a turbulent atmosphere, and an ocean of a composition that can only be postulated--makes the emergence of self-replicating molecules, let alone reproducing organisms, seem improbable indeed. Researchers attack the problem both from the bottom up, by trying to synthesize a system with self-replicating properties, and from the top down, by discerning how the biochemicals of the cell (ATP, RNA, proteins, etc.) function together. A tour of the exobiological potential of the solar system caps this lively presentation. Gilbert Taylor
