Addressing the emergence of life from a systems biology perspective, this new edition has undergone extensive revision, reflecting changes in scientific understanding and evolution of thought on the question 'what is life?'. With an emphasis on the philosophical aspects of science, including the epistemic features of modern synthetic biology, and also providing an updated view of the autopoiesis/cognition theory, the book gives an exhaustive treatment of the biophysical properties of vesicles, seen as the beginning of the 'road map' to the minimal cell - a road map which will develop into the question of whether and to what extent synthetic biology will be capable of making minimal life in the laboratory. Fully illustrated, accessibly written, directly challenging the reader with provocative questions, offering suggestions for research proposals, and including dialogues with contemporary authors such as Humberto Maturana, Albert Eschenmoser and Harold Morowitz, this is an ideal resource for researchers and students across fields including bioengineering, evolutionary biology, molecular biology, chemistry and chemical engineering. This new edition provides greater coverage of synthetic biology and includes discussions with contemporaries in the field. Beautifully illustrated with minimal jargon, making it suitable for a broad audience

Our knowledge of our solar system has passed the point of no return. Increasingly, it seems possible that scientists will soon discover how life is created on habitable planets like Earth and Mars. Scientists have responded to a renewed public interest in the origin of life with research, but many questions still remain unanswered in the broader conversation. Other questions can be answered by the laws of chemistry and physics, but questions surrounding the origin of life are best answered by reasonable extrapolations of what scientists know from observing the Earth and its solar system.Origin of Life: What Everyone Needs to Know® is a comprehensive scientific guide on the origin of life. David W. Deamer sets out to answer the top forty questions about the origin of life, including: Where do the atoms of life come from? How old is Earth? What was the Earth like before life originated? Where does water come from? How did evolution begin? After he provides the informational answer for each question, there is a follow-up: How do we know? This question expands the horizon of the whole book, and provides scientific reasoning and explanations for hypotheses surrounding the origin of life. How scientists come to their conclusions and why we can trust these answers is an important question, and Deamer provides answers to each big question surrounding the origin of life, from what it is to why we should be curious.

Sait-on que le fer, ce métal qui nous familier, a une histoire, qu'il est né au cœur d'une grosse étoile ? Sait-on que l'ancêtre de tous les éléments chimiques s'appelle l'hydrogène, comme l'ancêtre de tous les êtres vivants s'appelle bactérie ? Dans la Nature, le monde qui nous entoure, tout a une histoire : les formes, la matière, les êtres, les roches, les planètes. L'ensemble, ordonné depuis l'origine de l'Univers jusqu'à nos jours, constitue l'Histoire naturelle. Loin, par son contenu, des mythologies et des livres sacrés, et pourtant si proche par son objet, le récit auquel nous convie Claude Allègre est celui de la longue histoire du Temps. Partant de l'instant initial du big bang, il parcourt à grandes enjambées l'histoire des galaxies, des étoiles, de la Terre, de la Vie, de l'Homme, pour terminer son récit dans le... futur. Pour écrire cette histoire de la Nature, il utilise tout ce que la science moderne a apporté de découvertes depuis les observations astronomiques jusqu'à l'exploration du vivant, en passant par la tectonique des plaques ou l'émergence de l' Homme. De cette fresque se dégage une nouvelle vision des rapports de l'Homme à la Science, à la Connaissance, à Dieu, c'est-à-dire à ses propres incertitudes.
