The history of life on Earth is punctuated by half a dozen puzzling mass extinctions that constitute the benchmarks of the geologic time scale. These great breaks in the continuity of the fossil record have invited a wide array of scientific speculation. The most thoroughly studied of the mass extinctions occurred 65 million years ago when most life on Earth, incl. the dinosaurs, perished. Two rival hypotheses have emerged to account for this catastrophic event: the ''impactor'' hypothesis sees the earth bombarded with deadly meteorites, while the competing ''volcanist'' hypothesis evokes gigantic volcanic eruptions. This book examines the arguments & behavior of the scientists who have been locked in conflict over the competing hypotheses.

The science the protagonist pursue is alive with discovery, and their debates vibrate with conflict, right from the editor's opening chapter on the history of the arguments about competing extinction hypotheses and a host of other conflicts that the debates have spawned.
