A major new book overturning our assumptions about how evolution works Earth’s natural history is full of fascinating instances of convergence: phenomena like eyes and wings and tree-climbing lizards that have evolved independently, multiple times. But evolutionary biologists also point out many examples of contingency, cases where the tiniest change—a random mutation or an ancient butterfly sneeze—caused evolution to take a completely different course. What role does each force really play in the constantly changing natural world? Are the plants and animals that exist today, and we humans ourselves, inevitabilities or evolutionary flukes? And what does that say about life on other planets? Jonathan Losos reveals what the latest breakthroughs in evolutionary biology can tell us about one of the greatest ongoing debates in science. He takes us around the globe to meet the researchers who are solving the deepest mysteries of life on Earth through their work in experimental evolutionary science. Losos himself is one of the leaders in this exciting new field, and he illustrates how experiments with guppies, fruit flies, bacteria, foxes, and field mice, along with his own work with anole lizards on Caribbean islands, are rewinding the tape of life to reveal just how rapid and predictable evolution can be. Improbable Destinies will change the way we think and talk about evolution. Losos's insights into natural selection and evolutionary change have far-reaching applications for protecting ecosystems, securing our food supply, and fighting off harmful viruses and bacteria. This compelling narrative offers a new understanding of ourselves and our role in the natural world and the cosmos.

A dazzling tour of evolution in action that sheds light on one of the greatest debates in science The natural world is full of fascinating instances of convergence: phenomena like eyes and wings and tree-climbing lizards that have evolved independently, multiple times. Convergence suggests that evolution is predictable, and if we could replay the tape of life, we would get the same outcome. But there are also many examples of contingency, cases where the tiniest change - a random mutation or an ancient butterfly sneeze - caused evolution to take a completely different course. So are we humans, and all the plants and animals in the world today, inevitabilities or evolutionary freaks? What role does chance play in evolution? And what could it tell us about life on other planets? In Improbable Destinies, renowned researcher Jonathan Losos reveals what the latest breakthroughs in evolutionary biology tell us about one of the greatest ongoing debates in science. Evolution can occur far more rapidly than Darwin expected, which has opened the door to something that was previously thought impossible: experimental studies of evolution in nature. Drawing on his own work with anole lizards on the Caribbean islands, as well as studies of guppies, foxes, field mice and others being conducted around the world, Losos reveals just how rapid and predictable evolution can be. By charting the discoveries of the scientists who are rewriting our understanding of evolutionary biology, Improbable Destinies will change the way we think and talk about evolution.

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.

It is easy to think of evolution as something that happened long ago, or that occurs only in "nature," or that is so slow that its ongoing impact is virtually nonexistent when viewed from the perspective of a single human lifetime. But we now know that when natural selection is strong, evolutionary change can be very rapid. In this book, some of the world's leading scientists explore the implications of this reality for human life and society. With some twenty-three essays, this volume provides authoritative yet accessible explorations of why understanding evolution is crucial to human life—from dealing with climate change and ensuring our food supply, health, and economic survival to developing a richer and more accurate comprehension of society, culture, and even what it means to be human itself. Combining new essays with essays revised and updated from the acclaimed Princeton Guide to Evolution, this collection addresses the role of evolution in aging, cognition, cooperation, religion, the media, engineering, computer science, and many other areas. The result is a compelling and important book about how evolution matters to humans today. The contributors are Dan I. Andersson, Francisco J. Ayala, Amy Cavanaugh, Cameron R. Currie, Dieter Ebert, Andrew D. Ellington, Elizabeth Hannon, John Hawks, Paul Keim, Richard E. Lenski, Tim Lewens, Jonathan B. Losos, Virpi Lummaa, Jacob A. Moorad, Craig Moritz, Martha M.

Ten years after his bestseller Microtrends, Mark Penn identifies the next wave of trends reshaping the future of business, politics, and culture. Mark Penn has boldly argued that the future is not shaped by society’s broad forces but by quiet changes within narrow slices of the population. Ten years ago, he showed how the behavior of one small group can exert an outsized influence over the whole of America. His bestselling Microtrends highlighted dozens of tiny, counterintuitive trends that have since come to fruition, from the explosion of internet dating to the recent split within the Republican Party. Today, the world is in perplexing upheaval, and microtrends are more influential than ever. In this environment, Penn offers a necessary perspective. Microtrends Squared makes sense of what is happening in the world today. Through fifty new microtrends, Penn illuminates the shifts that are coming in the next decade. He pinpoints the unseen hand behind new power relationships that have emerged—as fringe voters and reactionary politics have found their revival, as online influencers overshadow traditional media, and as the gig economy continues to invade new swathes of industry. He speaks to the next wave of developments coming in technology, social movements, and even dating. Offering a clear vision of the future of business, politics, and culture, Microtrends Squared is a must-read for innovators and entrepreneurs, political and business leaders, and for every curious reader looking to under­stand the wave of the future when it is just a ripple.

"Why and how did life become so diverse? This has been a central problem in biology. Experimen-tal Evolution and the Nature of Biodiversity explores how diversity evolves in microbial popula-tions that occupy some of the simplest environments imaginable, laboratory test tubes. Microbial evolution experiments allow researchers to watch the evolutionary process unfold in real time while tracking diversification in both phenotype and genotype along the way. When combined with new insights coming from next-generation sequencing, these experiments can tell us much more about the sorts of problems and questions related to adaptation and diversity"--"Why and how did life become so diverse?
