This book emphasizes the interfaces between the seemingly diverse fields of biochemistry and cosmochemistry. This link provides the basis for understanding of how life began on Earth and whether this process is universal. This area of study helps us to understand the long-asked questions of whether there is life beyond Earth, and whether our planet is one example of how life could originate and evolve on other worlds. Biochemistry demonstrates how life has originated and evolved into complex life forms ranging from small microbial forms such as bacteria to the upright walking creatures we...

"A highly readable survey of the historical prelude to the study of the origins of life, as well as selected areas of current research, including the search for extraterrestrial life."-NatureWhere did we come from? Did life arise on earth or on some other planet? What did the earliest primitive organisms look like? Untangling a century of contentious debate, the authors explore current theories of the source of life-from Martian meteors to hydrothermal vents-and then present their own elegant scenario: Life arose not in the subterranean depths, as many believe, but on Earth's tumultuous...
