Showing results for "lifes a" in Evolution

Scientists' understanding of life is progressing more rapidly than at any point in human history, from the extraordinary decoding of DNA to the controversial emergence of biotechnology. Featuring pioneering biologists, geneticists, physicists, and science writers, Life explains just how far we've come - and takes a brilliantly educated guess at where we're heading.

Once, we humans could only observe evolution. Suddenly, we had conquered it. And yet, in Life as We Made It, evolutionary biologist Beth Shapiro argues that - despite how amazing our new technologies are - our ability to alter the course of evolution isn’t new. What is new is that where once we shaped evolution through brute force, we can now do it as artisans. That power comes not a moment too soon. If we are going to survive in the next few centuries, we must revise the book of life.

Australopithecines, dinosaurs, trilobites - such fossils conjure up images of lost worlds filled with vanished organisms. But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty.

To celebrate the 40th anniversary of the book's first publication, David Attenborough has revised Life on Earth, updating and adding to the original text and choosing beautiful, completely new photography. This special anniversary edition provides a fitting tribute to an enduring wildlife classic. It will enthral the generation who saw it when first published and will bring it alive for a whole new generation.

High in the Canadian Rockies is a small limestone quarry formed 530 million years ago called the Burgess Shale. It holds the remains of an ancient sea where dozens of strange creatures lived—a forgotten corner of evolution preserved in awesome detail. In this book, Stephen Jay Gould explores what the Burgess Shale tells us about evolution and the nature of history.

The world is in crisis! What is the solution? Ultimately, we have to find the redeeming, and thus transforming, understanding of our psychologically troubled human condition. And it is precisely that dreamed-of insight, and its now desperately needed transformation of our lives, that Australian biologist Jeremy Griffith presents in this book.

Science's greatest puzzle is where did we come from and how did we get here. This book shows how telling this story depends on understanding the gigantic family tree - the Tree of Life - that records the relationships between all species of life on earth - from humans, fish and butterflies to oak trees, mushrooms and bacteria. Knowing the Tree of Life unlocks the distant past letting us travel back in time to follow the twists and turns of life's history; it is what allows us to tell the very personal story that began four billion years ago.

Biology is undergoing a quiet but profound transformation. Several aspects of the standard picture of how life works—the idea of the genome as a blueprint, of genes as instructions for building an organism, of proteins as precisely tailored molecular machines, of cells as entities with fixed identities, and more—have been exposed as incomplete, misleading, or wrong. In How Life Works, Philip Ball explores the new biology, revealing life to be a far richer, more ingenious affair than we had guessed.

From that first foray to the spread of early hominids who later became Homo sapiens, life has persisted, undaunted. A (Very) Short History of Life is an enlightening story of survival, of persistence, illuminating the delicate balance within which life has always existed, and continues to exist today. It is our planet like you’ve never seen it before. Life teems through Henry Gee’s lyrical prose - colossal supercontinents drift, collide and coalesce, fashioning the face of the planet as we know it today.

It is widely understood that Charles Darwin’s theory of evolution completely revolutionized the study of biology. Yet, according to David Sloan Wilson, the Darwinian revolution won’t be truly complete until it is applied more broadly - to everything associated with the words “human,” “culture,” and “policy.”

It is now known that we live in a galaxy with more planets than stars. The Milky Way alone encompasses 30 trillion potential home planets. Scientists Trefil and Summers bring listeners on a marvelous experimental voyage through the possibilities of life-unlike anything we have experienced so far - that could exist on planets outside our own solar system.

Carl Zimmer investigates one of the biggest questions of all: What is life? The answer seems obvious until you try to seriously answer it. Is the apple sitting on your kitchen counter alive, or is only the apple tree it came from deserving of the word? If we can’t answer that question here on earth, how will we know when and if we discover alien life on other worlds? The question hangs over some of society’s most charged conflicts – whether a fertilized egg is a living person, for example, and when we ought to declare a person legally dead.

The cells in our bodies consist of molecules, made up of the same carbon, oxygen, and hydrogen atoms found in air and rocks. But molecules, such as water and sugar, are not alive. So how do our cells - assemblies of otherwise "dead" molecules - come to life, and together constitute a living being? In Life’s Ratchet, physicist Peter M. Hoffmann locates the answer to this age-old question at the nanoscale.

Seventy years ago, Erwin Schrdinger posed a simple, yet profound, question: What is life?. How could the very existence of such extraordinary chemical systems be understood? This problem has puzzled biologists and physical scientists both before, and ever since. Living things are hugely complex and have unique properties, such as self-maintenance and apparently purposeful behaviour which we do not see in inert matter. So how does chemistry give rise to biology?

Spontaneous generation of living organisms - life arising without progenitor or seed - was a common belief in the time of Aristotle. Over the next 2,000 years, support for spontaneous generation slowly retreated to its final stronghold: spontaneous formation of the first living organism.

Here is the extraordinary story of the unfolding of life on Earth, told by Michael J. Benton, a world-renowned authority on biodiversity. Ranging over four billion years, Benton weaves together the latest findings on fossils, earth history, evolutionary biology, and many other fields to highlight the great leaps that enabled life to evolve from microbe to human - big breakthroughs that made whole new ways of life possible - including cell division and multicellularity, hard skeletons, the move to land, the origin of forests, the move to the air.

Charles Darwin’s theories, first published more than 150 years ago, still set the paradigm of how we understand the evolution of life--but scientific advances of recent decades have radically altered that. Now two pioneering scientists draw on their years of experience in paleontology, biology, chemistry, and astrobiology to deliver an eye-opening narrative using a generation’s worth of insights culled from new research.

This pathbreaking book explores how life can begin, taking us from cosmic clouds of stardust, to volcanoes on Earth, to the modern chemistry laboratory. Seeking to understand life's connection to the stars, David Deamer introduces astrobiology, a new scientific discipline that studies the origin and evolution of life on Earth and relates it to the birth and death of stars, planet formation, interfaces between minerals, water, and atmosphere, and the physics and chemistry of carbon compounds.

For a long time, scientists have wondered how life has emerged from inanimate chemistry, and whether Earth is the only place where it exists. Charles Darwin speculated about life on Earth beginning in a warm little pond. Some of his contemporaries believed that life existed on Mars. It once seemed inevitable that the truth would be known by now. It is not. For more than a century, the origins and extent of life have remained shrouded in mystery. But, as Mario Livio and Jack Szostak reveal in Is Earth Exceptional?, the veil is finally lifting.

In Origin Story, medical historian Howard Markel recounts the two-year period (1858 to 1860) of Darwin's writing of On the Origin of Species through its spectacular success and controversy. Simultaneously, Markel delves into the mysterious health symptoms Darwin developed, combing the literature to emerge with a cogent diagnosis of a case that has long fascinated medical historians.
