The greatest mystery of life is how a single fertilized egg develops into a fully functioning, sometimes conscious multicellular organism. Embryogenesis Explained offers a new theory of how embryos build themselves, and combines simple physics with the most recent biochemical and genetic breakthroughs, based on the authors' prediction and then discovery of differentiation waves. They explain their ideas in a form accessible to the lay person and a broad spectrum of scientists and engineers. The diverse subjects of development, genetics and evolution, and their physics, are brought together to explain this major, previously unanswered scientific question of our time. As a follow up on The Hierarchical Genome, this book is a shorter but conceptually expanded work for the reader who is interested in science. It is useful as a starting point for the curious layman or the scientist or professional encountering the problem of embryogenesis without the formal biology background. There is also material useful for the seasoned biologist caught up in the new rush of information about the role of mechanics in developmental biology and cellular level mechanics in medicine.

This book explains why scientists believe that life may be more common in the Universe than previously considered possible. It presents the tools and strategies astronomers and astrobiologists are using in their formal search for habitable exoplanets as well as more advanced forms of life in other parts of our galaxy. The author then summarizes what is currently known about how and where organic molecules critical to our form of carbon-based life are manufactured. The core of the book explains (and presents educated guesses) how nervous systems evolved on Earth, how they work, and how they might work on other worlds. Combining his knowledge of neuroscience, computers, and astrobiology the author jumps into the discussion whether biological nervous systems are just the first step in the rise of intelligence in the Universe. The book ends with a description from both the psychologist’s and the neuroscientist’s viewpoints, exactly what it is about the fields of astrobiology and astronomy that “boggles the minds” of many amateur astronomers and interested non-scientists. This book stands out from other popular science books on astrobiology by making the point that “astro-neurobiologists” need to begin thinking about how alien nervous systems might work.

Divided into two parts, the first four chapters of Comets and their Origin refer to comets and their formation in general, describing cometary missions, comet remote observations, astrochemistry, artificial comets, and the chirality phenomenon. The second part covers the cometary ROSETTA mission, its launch, journey, scientific objectives, and instrumentations, as well as the landing scenario on a cometary nucleus. Along the way, the author presents general questions concerning the origin of terrestrial water and the molecular beginnings of life on Earth, as well as how the instruments used on a space mission like ROSETTA can help answer them. The text concludes with a chapter on what scientists expect from the ROSETTA mission and how its data will influence our life on Earth. As a result, the author elucidates highly topical and fascinating knowledge to scientists and students of various scientific backgrounds, allowing them to work with ROSETTA's data.

Randomness In Evolution

John Tyler Bonner, one of our most distinguished and insightful biologists, here challenges a central tenet of evolutionary biology. In this concise, elegantly written book, he makes the bold and provocative claim that some biological diversity may be explained by something other than natural selection. With his customary wit and accessible style, Bonner makes an argument for the underappreciated role that randomness--or chance--plays in evolution. Due to the tremendous and enduring influence of Darwin's natural selection, the importance of randomness has been to some extent overshadowed. Bonner shows how the effects of randomness differ for organisms of different sizes, and how the smaller an organism is, the more likely it is that morphological differences will be random and selection may not be involved to any degree. He traces the increase in size and complexity of organisms over geological time, and looks at the varying significance of randomness at different size levels, from microorganisms to large mammals. Bonner also discusses how sexual cycles vary depending on size and complexity, and how the trend away from randomness in higher forms has even been reversed in some social organisms. Certain to provoke lively discussion, Randomness in Evolution is a book that may fundamentally change our understanding of evolution and the history of life.

How Life Began

The origin of life is a hotly debated topic. The Christian Bible states that God created the heavens and the Earth, all in about seven days roughly six thousand years ago. This episode in Genesis departs markedly from scientific theories developed over the last two centuries which hold that life appeared on Earth about 3.5 billion years ago in the form of bacteria, followed by unicellular organisms half a millennia later. It is this version of genesis that Alexandre Meinesz explores in this engaging tale of life's origins and evolution. How Life Began elucidates three origins, or geneses, of life—bacteria, nucleated cells, and multicellular organisms—and shows how evolution has sculpted life to its current biodiversity through four main events—mutation, recombination, natural selection, and geologic cataclysm. As an ecologist who specializes in algae, the first organisms to colonize Earth, Meinesz brings a refreshingly novel voice to the history of biodiversity and emphasizes here the role of unions in organizing life. For example, the ingestion of some bacteria by other bacteria led to mitochondria that characterize animal and plant cells, and the chloroplasts of plant cells. As Meinesz charmingly recounts, life’s grandeur is a result of an evolutionary tendency toward sociality and solidarity. He suggests that it is our cohesion and collaboration that allows us to solve the environmental problems arising in the decades and centuries to come. Rooted in the science of evolution but enlivened with many illustrations from other disciplines and the arts, How Life Began intertwines the rise of bacteria and multicellular life with Vermeer’s portrait of Antoni van Leeuwenhoek, the story of Genesis and Noah, Meinesz’s son’s early experiences with Legos, and his own encounters with other scientists. All of this brings a very human and humanistic tone to Meinesz’s charismatic narrative of the three origins of life.

By one of Britain's most gifted scientists: a magnificently daring and compulsively readable account of life on Earth (from the "big bang" to the advent of man), based entirely on the most original of all sources--the evidence of fossils. With excitement and driving intelligence, Richard Fortey guides us from the barren globe spinning in space, through the very earliest signs of life in the sulphurous hot springs and volcanic vents of the young planet, the appearance of cells, the slow creation of an atmosphere and the evolution of myriad forms of plants and animals that could then be sustained, including the magnificent era of the dinosaurs, and on to the last moment before the debut of Homo sapiens. Ranging across multiple scientific disciplines, explicating in wonderfully clear and refreshing prose their findings and arguments--about the origins of life, the causes of species extinctions and the first appearance of man--Fortey weaves this history out of the most delicate traceries left in rock, stone and earth. He also explains how, on each aspect of nature and life, scientists have reached the understanding we have today, who made the key discoveries, who their opponents were and why certain ideas won. Brimful of wit, fascinating personal experience and high scholarship, this book may well be our best introduction yet to the complex history of life on Earth. A Book-of-the-Month Club Main Selection With 32 pages of photographs From the Hardcover edition.

Imagine primordial Earth, a churning cauldron of liquefied rock. Steaming, seething -- a vast desolate wasteland, inhospitable to life. Yet somehow first life appeared. Maybe chemicals in a primordial soup spontaneously spawned a single-celled creature that continued to evolve. Or perhaps a transcendent Creator formed and nurtured the initial life forms. To determine what really happened requires a framework to evaluate the evidence. For the first time in print, Dr. Rana and Dr. Ross present a scientific model for the creation of first life on Earth -- a model based on the Bible. They present testable predictions for this life-origins scenario and for the competing naturalistic scenarios. Which model withstands the rigorous scrutiny of science and the tests of time? The one that does gives insight to a deeper question: Why would the first life forms precede human life by billions of years? Book jacket.

At first, nothing lived on Earth. It was a noisy, hot, scary place. Choking gas exploded from volcanoes and oceans of lava bubbled around the globe... Then in the deep, dark ocean, something amazing happened. This is an exciting and dramatic story about how life began and developed on Planet Earth, written especially for younger children. The authors explain how the first living cell was created, and how the cells multiply and create jellyfish and worms, and then fish with bendy necks, which drag themselves out of the water into swampy forests. They tell the story of the biggest creatures that have ever walked on land - the dinosaurs. Long after that, hairy creatures who have babies, not eggs, take over, stand on two legs and spread around the world, some of them living through cataclysmic events such as ice ages and volcanic eruptions. Everyone living today is related to these survivors. With delightful illustrations including lots of detail and humour, all carefully researched and checked, this book shows the development of life on Earth in a truly accessible and simple way.
