by David W. Deamer (Author)
En El origen de la vida: lo que todo el mundo necesita saber, David W. Deamer ha escrito una guía completa sobre el origen de la vida que está organizada en tres secciones. La primera sección aborda preguntas como: De dónde provienen los átomos de la vida? Qué edad tiene la Tierra? Cómo era la Tierra antes de que comenzara la vida? De dónde viene el agua? Después de que se responde cada pregunta, hay un seguimiento: Cómo lo sabemos? Esto amplía el horizonte del libro, explicando cómo los científicos llegan a conclusiones y por qué podemos confiar en estas respuestas. La segunda sección describe cómo ciertas moléculas orgánicas pueden ensamblarse espontáneamente en poblaciones de protocélulas que pueden someterse a selección y evolucionar hacia sistemas vivos primitivos. Aquí Deamer propone un concepto verdaderamente novedoso de que la vida no comenzó en el océano sino en fuentes termales de agua dulce en masas de tierra volcánica que se asemejan a Hawaii hoy. El verdadero conocimiento no es solo lo que sabemos, sino que es igualmente importante lo que aún no sabemos. En la tercera sección, Deamer enumera las preguntas pendientes que deben abordarse antes de que podamos finalmente responder a una pregunta fundamental de la biología: Cómo puede comenzar la vida?
In Origin of Life: What Everyone Needs to Know, David W. Deamer has written a comprehensive guide to the origin of life that is organized in three sections. The first section addresses questions such as: Where do the atoms of life come from? How old is Earth? What was the Earth like before life began? Where does water come from? After each question is answered, there is a follow-up: How do we know? This expands the horizon of the book, explaining how scientists reach conclusions and why we can trust these answers. The second section describes how certain organic molecules can spontaneously assemble into populations of protocells that can undergo selection and evolve toward primitive living systems. Here Deamer proposes a truly novel concept that life did not begin in the ocean but instead in fresh water hot springs on volcanic land masses resembling Hawaii today. True knowledge is not just what we know, but equally important is what we don't yet know. In the third section Deamer lists the outstanding questions that must be addressed before we can finally answer a fundamental question of biology: How can life begin?
