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? The authors examine the latest research - in fields ranging from molecular biology to astronomy - on questions surrounding life's origins. They untangle a century of contentious debate and explore many theories, assessing the probability of everything from asteroids and Martian rocks to 'primordial soup' and volcanic vents. They 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 extra-terrestrial life.

In short, we think that the fierce pressures of Darwin's natural selection played a central role in the origin of life almost from the beginning that that life would never have appeared without them." (Pg. xii-xiii) Later, they add, "Arguments about the origin of life tend to have this strange recursive quality, circling maddeningly around the problem without ever quite coming to grips with it ...
