NATIONAL BESTSELLER • A groundbreaking work of science, history, and archaeology that radically alters our understanding of the Americas before the arrival of Columbus in 1492—from “a remarkably engaging writer” (The New York Times Book Review). Contrary to what so many Americans learn in school, the pre-Columbian Indians were not sparsely settled in a pristine wilderness; rather, there were huge numbers of Indians who actively molded and influenced the land around them. The astonishing Aztec capital of Tenochtitlan had running water and immaculately clean streets, and was larger than any contemporary European city. Mexican cultures created corn in a specialized breeding process that it has been called man’s first feat of genetic engineering. Indeed, Indians were not living lightly on the land but were landscaping and manipulating their world in ways that we are only now beginning to understand. Challenging and surprising, this a transformative new look at a rich and fascinating world we only thought we knew.

We have a strong instinct to belong to small groups defined by clear purpose and understanding--"tribes." This tribal connection has been largely lost in modern society, but regaining it may be the key to our psychological survival. Decades before the American Revolution, Benjamin Franklin lamented that English settlers were constantly fleeing over to the Indians-but Indians almost never did the same. Tribal society has been exerting an almost gravitational pull on Westerners for hundreds of years, and the reason lies deep in our evolutionary past as a communal species. The most recent example of that attraction is combat veterans who come home to find themselves missing the incredibly intimate bonds of platoon life. The loss of closeness that comes at the end of deployment may explain the high rates of post-traumatic stress disorder suffered by military veterans today. Combining history, psychology, and anthropology, Tribe explores what we can learn from tribal societies about loyalty, belonging, and the eternal human quest for meaning. It explains the irony that-for many veterans as well as civilians-war feels better than peace, adversity can turn out to be a blessing, and disasters are sometimes remembered more fondly than weddings or tropical vacations. Tribe explains why we are stronger when we come together, and how that can be achieved even in today's divided world.

Have you heard that language is violence and that science is sexist? Have you read that certain people shouldn't practice yoga or cook Chinese food? Or been told that being obese is healthy, that there is no such thing as biological sex, or that only white people can be racist? Are you confused by these ideas, and do you wonder how they have managed so quickly to challenge the very logic of Western society? In this probing and intrepid volume, Helen Pluckrose and James Lindsay document the evolution of the dogma that informs these ideas, from its coarse origins in French postmodernism to its refinement within activist academic fields. Today this dogma is recognizable as much by its effects, such as cancel culture and social-media dogpiles, as by its tenets, which are all too often embraced as axiomatic in mainstream media: knowledge is a social construct; science and reason are tools of oppression; all human interactions are sites of oppressive power play; and language is dangerous. As Pluckrose and Lindsay warn, the unchecked proliferation of these anti-Enlightenment beliefs present a threat not only to liberal democracy but also to modernity itself. While acknowledging the need to challenge the complacency of those who think a just society has been fully achieved, Pluckrose and Lindsay break down how this often-radical activist scholarship does far more harm than good, not least to those marginalized communities it claims to champion. They also detail its alarmingly inconsistent and illiberal ethics. Only through a proper understanding of the evolution of these ideas, they conclude, can those who value science, reason, and consistently liberal ethics successfully challenge this harmful and authoritarian orthodoxy—in the academy, in culture, and beyond.

The first comprehensive synthesis on development and evolution: it applies to all aspects of development, at all levels of organization and in all organisms, taking advantage of modern findings on behavior, genetics, endocrinology, molecular biology, evolutionary theory and phylogenetics to show the connections between developmental mechanisms and evolutionary change. This book solves key problems that have impeded a definitive synthesis in the past. It uses new concepts and specific examples to show how to relate environmentally sensitive development to the genetic theory of adaptive evolution and to explain major patterns of change. In this book development includes not only embryology and the ontogeny of morphology, sometimes portrayed inadequately as governed by "regulatory genes," but also behavioral development and physiological adaptation, where plasticity is mediated by genetically complex mechanisms like hormones and learning. The book shows how the universal qualities of phenotypes--modular organization and plasticity--facilitate both integration and change. Here you will learn why it is wrong to describe organisms as genetically programmed; why environmental induction is likely to be more important in evolution than random mutation; and why it is crucial to consider both selection and developmental mechanism in explanations of adaptive evolution. This book satisfies the need for a truly general book on development, plasticity and evolution that applies to living organisms in all of their life stages and environments. Using an immense compendium of examples on many kinds of organisms, from viruses and bacteria to higher plants and animals, it shows how the phenotype is reorganized during evolution to produce novelties, and how alternative phenotypes occupy a pivotal role as a phase of evolution that fosters diversification and speeds change. The arguments of this book call for a new view of the major themes of evolutionary biology, as shown in chapters on gradualism, homology, environmental induction, speciation, radiation, macroevolution, punctuation, and the maintenance of sex. No other treatment of development and evolution since Darwin's offers such a comprehensive and critical discussion of the relevant issues. Developmental Plasticity and Evolution is designed for biologists interested in the development and evolution of behavior, life-history patterns, ecology, physiology, morphology and speciation. It will also appeal to evolutionary paleontologists, anthropologists, psychologists, and teachers of general biology.
