Book Description
Darwin's Pangenesis and Its Rediscovery Part A highlights the findings of Darwin's Pangenesis, an expanded cell theory and unified theory of heredity and variation that strengthened his theory of evolution and explained many phenomena of life. Now, new advances and the discovery of circulating cell-free DNA, mobile RNAs, prions and extracellular vesicles are providing new breakthroughs, thus increasing evidence on the inheritance of acquired characters, graft hybridization, and many other phenomena that Pangenesis suggests. Sections of note in this volume include the rationale, criticisms, influence and recent molecular evidence of Darwin's Pangenesis, as well as its relation to the inheritance of acquired characters, which is often included under the blanket term "transgenerational epigenetic inheritance." - Presents a comprehensive approach to Darwin's Pangenesis, which is so little understood that few have recognized its far-reaching importance, but seems today surprisingly modern - Links Darwin's hypothetical gemmules with circulating cell-free DNA, mobile RNAs, prions and extracellular vesicles, shedding new light on an old theory - Includes section on Darwin's Pangenesis in relation to the Lamarckian inheritance of acquired characters, a central debate in the history of genetics

Book Description
In the early days, Plains Indians travelled on foot across the vast Canadian prairies, with only fierce, wolf-like dogs as companions. Later, with the arrival of Europeans, horses and canoes appeared on the scene. In Rediscovering the Prairies, Norman Henderson, a leading scholar of the world’s great temperate grasslands, revives the earlier modes of prairie travel. He journeys along 325 kilometres of Saskatchewan’s Qu’Appelle Valley by dog and travois (the wooden rack pulled by dogs and horses used by First Nations to transport belongings), then by canoe, and finally by horse and travois. Henderson’s often humourous descriptions of his attempts to find and train a dog and a horse highlight the difficulties involved in recreating traditional travel methods. Henderson interweaves his own adventures with the exploits of earlier travellers, such as La Vérendrye, Alexander Henry and Peter Fidler, and the experiences of fur traders and others who struggled across this strange and forbidding landscape. His captivating account will foster a better appreciation for, and a deeper understanding of, the natural and human history of the Canadian prairies.

Book Description
Darwin's Pangenesis and its Rediscovery Part B explores Darwin's Pangenesis, an expanded cell theory and unified theory of heredity and variation from over 150 years ago that strengthened his theory of evolution and explained many phenomena of life. Now, new discoveries on circulating DNA, mobile RNAs, prions and extracellular vesicles are providing striking evidence for the chemical existence of Darwin's imaginary gemmules. In addition, new evidence for the inheritance of acquired characters, graft hybridization, and many other phenomena that Pangenesis supposedly explains are progressing, and are hence explored in this comprehensive volume. Specific chapters in this new volume include Darwin and Mendel: The Historical Connection, Darwin's Pangenesis and Graft Hybridization, Darwin's Pangenesis and Medical Genetics, Darwin's Pangenesis and Certain Anomalous Phenomena, and Natural Selection and Pangenesis: The Darwinian Synthesis. - Presents the only book on Darwin's Pangenesis, an expanded cell theory and a unified theory of heredity, variation, development and reproduction - Highlights Darwin's tremendous contributions to genetics, as well as Mendel's legacy and limitations - Includes sections on Darwin's Pangenesis in relation to graft hybridization, medical genetics, evolutionary theory, along with many other updates

Book Description
The last decades of the 20th century witnessed strongly growing interest in evolutionary approaches to the human past. Even now, however, there is little real agreement on what evolutionary archaeology is all about. A major obstacle is the lack of consensus on how to define the basic principles of Darwinian thought in ways that are genuinely relevant to the archaeological sciences. Each chapter in this new collection of specially invited essays focuses on a single major concept and its associated key words, summarizes its historic and current uses, and then reviews case studies illustrating that concept's present and probable future role in research. What these authors say shows the richness and current diversity of thought among those today who insist that Darwinism has a key role to play in archaeology. Each chapter includes definitions of related key words. Because the same key words may have the same or different meanings in different conceptual contexts, many of these key words are addressed in more than one chapter. In addition to exploring key concepts, collectively the book's chapters show the broad range of ideas and opinions in this intellectual arena today. This volume reflects—and clarifies—debate today on the role of Darwinism in modern archaeology, and by doing so, may help shape the directions that future work in archaeology will take.

Book Description
A powerful new theory of human nature suggests that our secret to success as a species is our unique friendliness “Brilliant, eye-opening, and absolutely inspiring—and a riveting read. Hare and Woods have written the perfect book for our time.”—Cass R. Sunstein, author of How Change Happens and co-author of Nudge For most of the approximately 300,000 years that Homo sapiens have existed, we have shared the planet with at least four other types of humans. All of these were smart, strong, and inventive. But around 50,000 years ago, Homo sapiens made a cognitive leap that gave us an edge over other species. What happened? Since Charles Darwin wrote about “evolutionary fitness,” the idea of fitness has been confused with physical strength, tactical brilliance, and aggression. In fact, what made us evolutionarily fit was a remarkable kind of friendliness, a virtuosic ability to coordinate and communicate with others that allowed us to achieve all the cultural and technical marvels in human history. Advancing what they call the “self-domestication theory,” Brian Hare, professor in the department of evolutionary anthropology and the Center for Cognitive Neuroscience at Duke University and his wife, Vanessa Woods, a research scientist and award-winning journalist, shed light on the mysterious leap in human cognition that allowed Homo sapiens to thrive. But this gift for friendliness came at a cost. Just as a mother bear is most dangerous around her cubs, we are at our most dangerous when someone we love is threatened by an “outsider.” The threatening outsider is demoted to sub-human, fair game for our worst instincts. Hare’s groundbreaking research, developed in close coordination with Richard Wrangham and Michael Tomasello, giants in the field of cognitive evolution, reveals that the same traits that make us the most tolerant species on the planet also make us the cruelest. Survival of the Friendliest offers us a new way to look at our cultural as well as cognitive evolution and sends a clear message: In order to survive and even to flourish, we need to expand our definition of who belongs.

Book Description
As the study of Palaeolithic technologies moves towards a more analytical approach, it is necessary to determine a consistent procedural framework. The contributions to this timely and comprehensive volume do just that. This volume incorporates a broad chronological and geographical range of Palaeolithic material from the Lower to Upper Palaeolithic. The focus of this volume is to provide an analysis of Palaeolithic technologies from a quantitative, empirical perspective. As new techniques, particularly quantitative methods, for analyzing Palaeolithic technologies gain popularity, this work provides case studies particularly showcasing these new techniques. Employing diverse case studies, and utilizing multivariate approaches, morphometrics, model-based approaches, phylogenetics, cultural transmission studies, and experimentation, this volume provides insights from international contributors at the forefront of recent methodological advances.

Book Description
Nurturing Our Humanity offers a new perspective on our personal and social options in today's world, showing how we can build societies that support our great human capacities for consciousness, caring, and creativity. It brings together findings--largely overlooked--from the natural and social sciences debunking the popular idea that we are hard-wired for selfishness, war, rape, and greed. Its groundbreaking new approach reveals connections between disturbing trends like climate change denial and regressions to strongman rule. Moving past right vs. left, religious vs. secular, Eastern vs. Western, and other familiar categories that do not include our formative parent-child and gender relations, it looks at where societies fall on the partnership-domination scale. On one end is the domination system that ranks man over man, man over woman, race over race, and man over nature. On the other end is the more peaceful, egalitarian, gender-balanced, and sustainable partnership system. Nurturing Our Humanity explores how behaviors, values, and socio-economic institutions develop differently in these two environments, documents how this impacts nothing less than how our brains develop, examines cultures from this new perspective (including societies that for millennia oriented toward partnership), and proposes actions supporting the contemporary movement in this more life-sustaining and enhancing direction. It shows how through today's ever more fearful, frenzied, and greed-driven technologies of destruction and exploitation, the domination system may lead us to an evolutionary dead end. A more equitable and sustainable way of life is biologically possible and culturally attainable: we can change our course.

Book Description
Cultural evolution, much like general evolution, works from the assumption that cultures are descendent from much earlier ancestors. Human culture manifests itself in forms ranging from the small bands of hunters, through intermediate scale complex hunter-gatherers and farmers, to the high density urban settlements and complex polities that characterize much of today’s world. The chapters in the volume examine the dynamic interaction between the micro- and macro-scales of cultural evolution, developing a theoretical approach to the archaeological record that has been termed evolutionary processual archaeology. The contributions in this volume integrate positive elements of both evolutionary and processualist schools of thought. The approach, as explicated by the contributors in this work, offers novel insights into topics that include the emergence, stasis, collapse and extinction of cultural patterns, and development of social inequalities. Consequently, these contributions form a stepping off point for a significant new range of cultural evolutionary studies.
