We not only share nearly 99% of our genes with chimps, we also have some 35% in common with daffodils. Throughout much of the animal and even plant kingdoms, almost the same ancient genes code for almost the same proteins. And further, to everyone's astonishment, the genes involved in making the complex eyes of fruitflies are close matches to those involved in making the very different eyes of octopuses and people. So what leads to the nature's 'endless forms most beautiful'? The key to this mystery is being unravelled by 'Evo Devo' or the new science of evolutionary development biology. By looking at how a single-celled egg gives rise to a complex, multi-billion celled animal, Evo Devo is illuminating exactly how new species - butterflies and zebras, trilobites and dinosaurs, apes and humans - are made and evolved. The key, it turns out, is all about location and timing... For anyone who has ever pondered 'where did I come from', Endless Forms Most Beautiful explores our history, both the journey we have all made from egg to adult, and the long trek from the origin of life to the very recent origin of our species.

“A beautiful and very important book.”—Lewis Wolpert, American Scientist For over a century, opening the black box of embryonic development was the holy grail of biology. Evo Devo—Evolutionary Developmental Biology—is the new science that has finally cracked open the box. Within the pages of his rich and riveting book, Sean B. Carroll explains how we are discovering that complex life is ironically much simpler than anyone ever expected.

An analysis of convergent evolution from molecules to ecosystems, demonstrating the limited number of evolutionary pathways available to life. Charles Darwin famously concluded On the Origin of Species with a vision of "endless forms most beautiful" continually evolving. More than 150 years later many evolutionary biologists see not endless forms but the same, or very similar, forms evolving repeatedly in many independent species lineages. A porpoise's fishlike fins, for example, are not inherited from fish ancestors but are independently derived convergent traits. In this book, George McGhee describes the ubiquity of the phenomenon of convergent evolution and connects it directly to the concept of evolutionary constraint--the idea that the number of evolutionary pathways available to life are not endless, but quite limited. Convergent evolution occurs on all levels, from tiny organic molecules to entire ecosystems of species. McGhee demonstrates its ubiquity in animals, both herbivore and carnivore; in plants; in ecosystems; in molecules, including DNA, proteins, and enzymes; and even in minds, describing problem-solving behavior and group behavior as the products of convergence. For each species example, he provides an abbreviated list of the major nodes in its phylogenetic classification, allowing the reader to see the evolutionary relationship of a group of species that have independently evolved a similar trait by convergent evolution. McGhee analyzes the role of functional and developmental constraints in producing convergent evolution, and considers the scientific and philosophical implications of convergent evolution for the predictability of the evolutionary process.

For the readers of The Language of God, another instant classic from "a sophisticated and original scholar" (Kirkus Reviews) that disputes the idea that science is contrary to religion. In The Science of God, distinguished physicist and Biblical scholar Gerald L. Schroeder demonstrates the surprising parallels between a variety of Biblical teachings and the findings of biochemists, paleontologists, astrophysicists, and quantum physicists. In a brilliant and wide-ranging discussion of key topics that have divided science and religion—free will, the development of the universe, the origin of life, and the origin of man—Schroeder argues that the latest science and a close reading of the Bible are not just compatible but interdependent. This timely reissue of The Science of God features a brand-new preface by Schroeder and a compelling appendix that addresses the highly publicized experiment in 2008 in which scientists attempted to re-create the chemical composition of the cosmos immediately after the Big Bang. It also details Schroeder’s lucid explanations of complex scientific and religious concepts, such as the theory of relativity, the passage of time, and the definitions of crucial Hebrew words in the Bible. Religious skeptics, Biblical literalists, scientists, students, and physicists alike will be riveted by Schroeder’s remarkable contribution to the raging debate between science and religion.

Plants are so much part of our environment that we often take them for granted, yet beautiful, fascinating and useful plants are everywhere, from isolated moss colonies on stone walls to vast complex communities within tropical rainforests. How did this array of form and habitat come about, and how do we humans interact with the plant kingdom? This unique new textbook provides a refreshing and stimulating consideration of these questions and throws light in a new way on the complexity, ecology, evolution and development of plants and our relationship with them. Illustrated throughout with numerous line diagrams and beautiful colour photographs, the book provides a comprehensive introduction to the fascinating lives that plants lead and the way in which our lives are inextricably linked to theirs. It will be particularly useful to students seeking a more ecological and process-oriented approach than is available in other plant science textbooks.

Teeth are amazing - the product of half a billion years of evolution. They provide fuel for the body by breaking apart other living things; and they must do it again and again over a lifetime without themselves being broken in the process. This means that plants and animals have developed tough or hard tissues for protection, and teeth have evolved ways to sharpen or strengthen themselves to overcome those defences. And just as different jobs require different tools, animals with different diets have different shaped teeth to deal with the variety of foods that they eat. In this Very Short Introduction, Peter S. Ungar, an award-winning author and leading scientist, presents the story of teeth. Ungar outlines the key concepts, including insights into the origin of teeth and their evolution. Considering why teeth are important, he describes how they are made, and how they work, including their fundamental importance in the fossil record. Ungar finishes with a review of mammal teeth, looking at how they evolved and how recent changes to our diet are now affecting dental health. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

In an age of increasing environmental problems, ecology has had to grow up fast from a discipline dealing with relatively simple interactions between species to one that tries to explain changes in global patterns of diversity and richness. The issues are complex. Every species may seem to have its own unique role, but if that is true, then why are there hundreds of species of plankton in an ecosystem with only a handful of niches? The tropics have a high biodiversity, but does anybody know why? And how can a single introduced tree species wreak havoc in Hawaii’s rainforests, when it is one of thousands of quietly coexisting tree species in its native continent, South America? The strength of this book is that it will help digest some of these more complex issues in the ecology of biodiversity. It will do this by zooming out from the local scale to the global scale in a number of steps, marrying community ecology with macroecology, and introducing unexpected nuggets of natural history along the way. The reader will notice that, the larger the scale, the more the familiar niche-concept appears to be overshadowed by exotic fields from fractal and complexity theory. However, scientists differ in opinion on the scale at which niches become irrelevant. These differences of opinion, but also the search for unified ecological theories, will form another force by which the story will be carried along to its conclusion. A conclusion which, surprisingly, seeks to find a glimpse of the globe's future in the traces from its past.

Grand Winner of the 2014 Nautilus Book Awards Thoughtful observers agree that the planetary crisis we now face-climate change; species extinction; the destruction of entire ecosystems; the urgent need for a more just economic-political order-is pushing human civilization to a radical turning point: change or perish. But precisely how to change remains an open question. In Earth-honoring Faith, Larry Rasmussen answers that question with a dramatically new way of thinking about human society, ethics, and the ongoing health of our planet. Rejecting the modern assumption that morality applies to human society alone, Rasmussen insists that we must derive a spiritual and ecological ethic that accounts for the well-being of all creation, as well as the primal elements upon which it depends: earth, air, fire, water, and sunlight. He argues that good science, necessary as it is, will not be enough to inspire fundamental change. We must draw on religious resources as well to make the difficult transition from an industrial-technological age obsessed with consumption to an ecological age that restores wise stewardship of all life. Earth-honoring Faith advocates an alliance of spirituality and ecology, in which the material requirements for planetary life are reconciled with deep traditions of spirituality across religions, traditions that include mysticism, sacramentalism, prophetic practices, asceticism, and the cultivation of wisdom. It is these shared spiritual practices that can produce a chorus of world faiths to counter the consumerism, utilitarianism, alienation, oppression, and folly that have pushed us to the brink. Written with passionate commitment and deep insight, Earth-honoring Faith reminds us that we must live in the present with the knowledge that the eyes of future generations will look back at us.
