摘要

Anyone who has undertaken scientific research knows that pursuit of "the truth" is seldom straightforward. This has certainly been the case for ecologist Paul Colinvaux, as he describes in his book Amazon Expeditions: My Quest for the Ice-Age Equator. The story is part picaresque and part polemic, at once a tale of adventure and a firsthand account of the deconstruction of a "beautiful" theory. The adventure story recounts the details of many expeditions over the course of half a lifetime by the author and his students to tropical South America, including the Galapagos Islands, Ecuador and Brazil. The purpose of their travels was to search for lakes containing mud dating from the last glacial maximum (the time when the ice sheets were at their greatest extent, about 20,000 to 25,000 years ago) or earlier. Such sediment, they believed, would contain clues about the nature of climate and vegetation during a key period of Earth's history.
