How did life emerge on Earth? Is there life on other worlds? These questions, until recently confined to the pages of speculative essays and tabloid headlines, are now the subject of legitimate scientific research. This book presents a unique perspective--a combined historical, scientific, and philosophical analysis, which does justice to the complex nature of the subject. The book's first part offers an overview of the main ideas on the origin of life as they developed from antiquity until the twentieth century. The second, more detailed part of the book examines contemporary theories and major debates within the origin-of-life scientific community. Topics include: Aristotle and the Greek atomists' conceptions of the organism Alexander Oparin and J.B.S. Haldane's 1920s breakthrough papers Possible life on Mars?

The Royal Society's Science Book of the Year "[A]n exuberant romp through evolution, like a modern-day Willy Wonka of genetic space. Gee’s grand tour enthusiastically details the narrative underlying life’s erratic and often whimsical exploration of biological form and function.” —Adrian Woolfson, The Washington Post In the tradition of Richard Dawkins, Bill Bryson, and Simon Winchester—An entertaining and uniquely informed narration of Life's life story. In the beginning, Earth was an inhospitably alien place—in constant chemical flux, covered with churning seas, crafting its landscape through incessant volcanic eruptions. Amid all this tumult and disaster, life began. The earliest living things were no more than membranes stretched across microscopic gaps in rocks, where boiling hot jets of mineral-rich water gushed out from cracks in the ocean floor. Although these membranes were leaky, the environment within them became different from the raging maelstrom beyond. These havens of order slowly refined the generation of energy, using it to form membrane-bound bubbles that were mostly-faithful copies of their parents—a foamy lather of soap-bubble cells standing as tiny clenched fists, defiant against the lifeless world. Life on this planet has continued in much the same way for millennia, adapting to literally every conceivable setback that living organisms could encounter and thriving, from these humblest beginnings to the thrilling and unlikely story of ourselves. In A (Very) Short History of Life on Earth, Henry Gee zips through the last 4.6 billion years with infectious enthusiasm and intellectual rigor. Drawing on the very latest scientific understanding and writing in a clear, accessible style, he tells an enlightening tale of survival and persistence that illuminates the delicate balance within which life has always existed.

An engaging account of our quest for habitable environments, recounting fascinating recent discoveries and providing insight into future space missions.

What's happening in the world lately? What happens when we die? Do secret societies have any real secrets? How do we know or find our purpose? What's real? What matters? Many of us ask ourselves these questions to try and make sense of our lives. Mike Dooley asks them too, except... his questions get answered. One such answer explained its source, stating that we all have a higher self within that predates this life and will live beyond it, and thus already knows where we've been, why we're here and what will happen next on our planet. Life on Earth takes the form of a journal in which Mike asks what's on his mind during pivotal times in his life, and takes on topics such as: - How to make sense of natural disasters and man-made tragedies - Living deliberately and creating consciously - Wealth, relationships, 'past lives' and consciousness - The ultimate reason for life on Earth (hint: it's not what you think) Mike Dooley asks questions from the heart with a cautious, even suspicious mind, and explores the answers, as always, with infinite wisdom and compassion.

Origins of Life on the Earth and in the Cosmos, Second Edition, suggests answers to the age-old questions of how life arose in the universe and how it might arise elsewhere. This thorough revision of a very successful text describes key events in the evolution of living systems, starting with the creation of an environment suitable for the origins of life. Whereas one may never be able to reconstruct the precise pathway that led to the origin of life on earth, one can certainly make some plausible reconstructions of it. Such discussions have greatly expanded our understanding of the principles of chemical evolution and how they compare and contrast with the principles of biological evolution. The text is strong on biochemistry and its recent applications to origins' research. - Provides an excellent review of basic biochemistry an evolution - Written in a clear, concise style for scientists, students, and readers interested in a scientific inquiry into the origins of life - Written by an authority in the field, and brought fully up-to-date in light of new research - Pulls together valuable information not found in a single source - Organized and presented in a manner conductive for use in a college course - Heavily illustrated to make difficult concepts concrete
