“This is history told by a scientist who helped to make it. . . . His book walks the reader through his fascinating journey to understand how life evolved. Today, Forterre believes that viruses played a vital part. Microbes from Hell, in interweaving a scientific life with the grand discovery of the archaea, is a wonderful homage to this exciting field, which continues to challenge our view of life’s origins.”

“The discovery of archaea not only changed the shape of the tree of life; it also raised questions about the common ancestor at the base of that tree and offered clues about how it may have lived. Forterre guides you through the different ideas and how they developed, including an unexpected role for viruses. This is what the book has been building towards, a rewarding discussion of competing theories about the ancestor of all living things by one of the scientists involved in the debate. As all the pieces come together, you’re left in a richer world, one full of unknown wonders, unanswered questions, and broader horizons.”

“Scientists who deal in the history of life have never been quite sure what to do with viruses. . . . Viruses, Forterre argues, bequeathed DNA to all living things. Trace the ancestry of your genes back far enough, in other words, and you bump into a virus. Other experts on the early evolution of life see Forterre’s theory as bold and significant. But although they find much to agree with—particularly the importance of viruses to evolution—many also regard Forterre’s ideas as controversial. . . . Forterre himself is trying to fill that gap by studying viruses that live in heat-loving archaeans. Archaean viruses are proving to be particularly diverse and bizarre—such as lemon-shaped species that don’t finish growing until they have left their host cell. Because viruses have such ancient roots, they preserve a remarkable range of biochemical tricks.”

“This excellent, brief book from one of the key players in the fields of microbiology and the evolution of hyperthermophiles discusses not only the microbes but also the major scientists who discovered and study them. Forterre does this in a most interesting and humorous, but also tactful, manner, without losing the focus on the science. Exceptionally well-planned and written in a vivid, most engaging style, the entire presentation has a thrilling sense of immediacy and excitement. In large part, this is because the study of hyperthermophiles is by no account limited to the laboratory bench. An integral aspect of this work includes expeditions to areas of hydrothermal activity, both high up in the mountains and deep down on the ocean floor. Apart from these exotic aspects, Forterre does an excellent job in conveying the excitement of research itself, in particular by providing a simple but accurate exposition of the logic of comparative genomic analysis. Highly educational, accessible, and well balanced.”

“Among the recent adventurers in science, Forterre makes his mark with this exciting book that brings us along on the discovery of life in extreme environments, a surprising and little-known world that thrived in the past and continues to thrive, and even evolve, today. . . . The book (but not the adventure!) concludes while raising the question of the origins of life. . . . A question that never ceases to stimulate the passion of the new pioneers of science, a passion that Forterre succeeds so well in sharing with the reader.”

“Scientists and industrial researchers study these incredible microbes to tap into the extraordinary strength of their proteins for numerous applications. Through the proteins they produce, these microbes have in fact already paved the way for the sequencing of the human genome and the identification of genetic fingerprints in a hair or sperm! Where do these extreme microbes come from, how are they related to us, how have they adapted to the diabolical conditions of their environments, and have they always lived there?—questions to understand how life began on Earth.”
