Most important, it is the unexpected appearance of a large \u003cb\u003ecomet\u003c/b\u003e that has the \u003cbr\u003e\nmost potential for truly catastrophic results, from which recovery may be \u003cbr\u003e\nimpossible. ... a cometary false alarm or the detection of a relatively small \u003cbr\u003e\n\u003cb\u003easteroid\u003c/b\u003e (like Tunguska) on a \u003cb\u003ecollision\u003c/b\u003e course with the Earth. ... and maintenance \u003cbr\u003e\nof expensive and inherently risky “\u003cb\u003espace\u003c/b\u003e defenses” in advance of the discovery of \u003cbr\u003e\na specific \u003cb\u003ethreat\u003c/b\u003e.

This volume considers the role comets may have played in the origins and evolution of life. This is the only book dealing in depth with this subject. It is particularly relevant in light of recent investigations of Halley's comet, of new insights into organic synthesis in meteorites and comets, and of new results of numerical simulations of cometary orbits and impacts on Earth. The book is intended as a comprehensive review of current research.
