What would life on other planets look like? Forget the little green men, alien life is likely to be completely unrecognisable -we haven't even discovered all the life on our own planet. This visionary book offers some of the most radical but scientifically accurate thinking on the possibility of life on other planets ever conceived. Using broad principles of Earthly biology and expanding on them laterally, Cohen and Stewart examine what could be out there. Redefining our whole concept of what 'life' is, they ask whether aliens could live on the surface of a star, in the vacuum of space or beneath the ice of a frozen moon. And whether life could exist without carbon or DNA -or even without matter at all. They also look at 'celebrity aliens' from books and films -most of which are biologically impossible. Jack Cohen is an 'alien consultant' to many writers, advising what an alien could and couldn't look like. (E. T. go home -you do not pass the test). But this book is as much about the latest discoveries in Earthly biology as well as life on other planets. It's a serious yet entertaining science book, as you'd expect from the bestselling authors of THE SCIENCE OF DISCWORLD.

"A fascinating and useful handbook to both the science and science fiction of extraterrestrial life. Cohen and Stewart are amusing, opinionated, and expert guides. I found it a terrific and informative piece of work-nothing else like it!" -Greg Bear "I loved it." -Larry Niven "Ever wonder about what aliens could be like? The world authority is Jack Cohen, a professional biologist who has thought long and hard about the vast realm of possibilities. This is an engaging, swiftly moving study of alien biology, a subject with bounds and constraints these authors plumb with verve and intelligence." -Gregory Benford "A celebration of life off Earth. A hearteningly optimistic book, giving a much-needed antidote to the pessimism of astrobiologists who maintain that we are alone in the universe-a stance based on a very narrow view of what could constitute life. A triumph of speculative nonfiction." -Dougal Dixon, author of After Man: A Zoology of the Future

Nature's Magic presents a bold vision of the evolutionary process from the Big Bang to the 21st century. Synergy of various kinds is not only a ubiquitous aspect of the natural world but it has also been a wellspring of creativity and the 'driver' of the broad evolutionary trend toward increased complexity, in nature and human societies alike. But in contrast with the many theories of emergence or complexity that rely on some underlying force or 'law', the 'Synergism Hypothesis', as Peter Corning calls it, is in essence an economic theory of biological complexity; it is fully consistent with mainstream evolutionary biology. Corning refers to it as Holistic Darwinism. Among the many important insights that are provided by this new paradigm, Corning presents a scenario in which the human species invented itself; synergistic, behavioral and technological innovations were the 'pacemakers' of our biological evolution. Synergy has also been the key to the evolution of complex modern societies, he concludes.

From the host of "Bill Nye the Science Guy" comes an impassioned explanation of how the science of our origins is fundamental to our understanding of the nature of science

Could “UFOs” and “Aliens” simply be us, but from the future? This provocative new book cautiously examines the premise that extraterrestrials may instead be our distant human descendants, using the anthropological tool of time travel to visit and study us in their own hominin evolutionary past. Dr. Michael P. Masters, a professor of biological anthropology specializing in human evolutionary anatomy, archaeology, and biomedicine, explores how the persistence of long-term biological and cultural trends in human evolution may ultimately result in us becoming the ones piloting these disc-shaped craft, which are likely the very devices that allow our future progeny to venture backward across the landscape of time. Moreover, these extratempestrials are ubiquitously described as bipedal, large-brained, hairless, human-like beings, who communicate with us in our own languages, and who possess technology advanced beyond, but clearly built upon, our own. These accounts, coupled with a thorough understanding of the past and modern human condition, point to the continuation of established biological and cultural trends here on Earth, long into the distant human future.

The Ape that Understood the Universe is the story of the strangest animal in the world: the human animal. It opens with a question: How would an alien scientist view our species? What would it make of our sex differences, our sexual behavior, our altruistic tendencies, and our culture? The book tackles these issues by drawing on two major schools of thought: evolutionary psychology and cultural evolutionary theory. The guiding assumption is that humans are animals, and that like all animals, we evolved to pass on our genes. At some point, however, we also evolved the capacity for culture - and from that moment, culture began evolving in its own right. This transformed us from a mere ape into an ape capable of reshaping the planet, travelling to other worlds, and understanding the vast universe of which we're but a tiny, fleeting fragment. Featuring a new foreword by Michael Shermer.

In Alien Species and Evolution, biologist George W. Cox reviews and synthesizes emerging information on the evolutionary changes that occur in plants, animals, and microbial organisms when they colonize new geographical areas, and on the evolutionary responses of the native species with which alien species interact. The book is broad in scope, exploring information across a wide variety of taxonomic groups, trophic levels, and geographic areas. It examines theoretical topics related to rapid evolutionary change and supports the emerging concept that species introduced to new physical and biotic environments are particularly prone to rapid evolution. The author draws on examples from all parts of the world and all major ecosystem types, and the variety of examples used gives considerable insight into the patterns of evolution that are likely to result from the massive introduction of species to new geographic regions that is currently occurring around the globe. Alien Species and Evolution is the only state-of-the-art review and synthesis available of this critically important topic, and is an essential work for anyone concerned with the new science of invasion biology or the threats posed by invasive species.
