Fascinating general account of microbial life on earth - how microbes have adapted to apparently impossible habitats; why they are able to survive in superheated water or supercooled brine; at enormous pressures; without air; amid poisons. Postgate also provides clues on the role of microbes in the origin and evolution of terrestrial life, and offers glimpses of how life might have established itself elsewhere in the universe.
