When and how did the brains of our hominin ancestors become human minds? When and why did our capacity for language or art, music and dance evolve? It is the contention of this pathbreaking and provocative book that it was the need for early humans to live in ever-larger social groups, and to maintain social relations over ever-greater distances - the ability to `think big' - that drove the enlargement of the human brain and the development of the human mind. This `social brain hypothesis', put forward by evolutionary psychologists such as Robin Dunbar, one of the authors of this book, can be tested against archaeological and fossil evidence, as archaeologists Clive Gamble and John Gowlett show in the second part of Thinking Big. Along the way, the three authors touch on subjects as diverse and diverting as the switch from finger-tip grooming to vocal grooming or the crucial importance of making fire for the lengthening of the social day. As this remarkable book shows, it seems we still inhabit social worlds that originated deep in our evolutionary past - by the fireside, in the hunt and on the grasslands of Africa.
If theoretical physicists can seriously entertain canonical "standard models" even for the big-bang generation of the entire universe, why cannot life scientists reach a consensus on how life has emerged and settled on this planet? Scientists are hindered by conceptual gaps between bottom-up inferences (from early Earth geological conditions) and top-down extrapolations (from modern life forms to common ancestral states). This book challenges several widely held assumptions and argues for alternative approaches instead. Primal syntheses (literally or figuratively speaking) are called for in at least five major areas. (1) The first RNA-like molecules may have been selected by solar light as being exceptionally photostable. (2) Photosynthetically active minerals and reduced phosphorus compounds could have efficiently coupled the persistent natural energy flows to the primordial metabolism. (3) Stochastic, uncoded peptides may have kick-started an ever-tightening co-evolution of proteins and nucleic acids. (4) The living fossils from the primeval RNA World thrive within modern cells. (5) From the inherently complex protocellular associations preceding the consolidation of integral genomes, eukaryotic cell organization may have evolved more naturally than simple prokaryote-like life forms. - If this book can motivate dedicated researchers to further explore the alternative mechanisms presented, it will have served its purpose well.
Anyone interested in comparative biology or the history of science will find this myth-busting work genuinely fascinating. It draws attention to the seminal studies and important advances that have shaped systematic and biogeographic thinking. It traces concepts in homology and classification from the 19th century to the present through the provision of a unique anthology of scientific writings from Goethe, Agassiz, Owen, Naef, Zangerl and Nelson, among others.
Nine chapters on diverse topics that include: an analysis of whether sociobiology has killed ethology or revitalized it; aims, limitations, and the future of ethology and comparative ethology; the tyranny of anthropocentrism; psychoimmunology; gender differences in behavior; behavioral development.
We have come a long way towards better understanding how new species originate, i.e. speciation, which long remained Darwin's "mystery of mysteries." Since speciation is the underlying mechanism for radiations, it is the ultimate causation for the biological diversity of life that surrounds us. Without a doubt, Charles Darwin's contribution to our understanding of the origin of biodiversity cannot be overestimated. This book is a contribution to both the Darwin Year we celebrated in 2009 and to the Year of Biodiversity and Conservation 2010. The studies and model cases presented show the progress and dynamics of research based on Darwinian theories and sheds light on its implications in the context of current biodiversity crises. The great importance of adaptive (and non-adaptive) radiations for biodiversity is widely accepted, but our understanding of the processes and mechanisms involved is still limited and generalizations need to be based on the accumulation of more evidence from additional case studies. The studies presented in this volume are those urgently needed and focus on a variety of organisms and different aspects of radiations. The scientific results presented therein are excellent examples not only of evolution in action, but also of active research on evolutionary processes and their most apparent outcome -- biodiversity.
Soon to be a major motion picture
Newborn mammals can weigh as little as a dime or as much as a motorcycle. Some receive milk for only a few days, whereas others nurse for years. Humans typically have only one baby at a time following nine months of pregnancy, but other mammals have twenty or more young after only a few weeks in utero. What causes this incredible reproductive diversity? In Reproduction in Mammals, Virginia Hayssen and Teri Orr present readers with a fascinating examination of the varied reproductive strategies of a broad spectrum of mammals, from marsupials to whales. This unique book's comprehensive coverage gathers stories from many taxa into a single, cohesive perspective that centers on the reproductive lives of females. The authors shed light on a number of intriguing questions, including * do bigger moms have bigger babies?* do primates have longer pregnancies than other groups?* does habitat influence animals' reproductive patterns?* do carnivores typically produce larger litters than prey species? The book opens with the authors' definition of what constitutes a female perspective and an examination of the evolution of reproduction in mammals. It then outlines the typical individual mammalian female: her genetics, anatomy, and physiology. Taking a nuanced approach, Hayssen and Orr describe the female reproductive cycle and explore female mammals' interactions with males and offspring. Readers will come away from this thought-provoking book with an understanding not only of how reproduction fits into the lives of female mammals but also of how biology has affected the enormously diverse reproductive patterns of the phenotypes we observe today.

Our knowledge of our solar system has passed the point of no return. Increasingly, it seems possible that scientists will soon discover how life is created on habitable planets like Earth and Mars. Scientists have responded to a renewed public interest in the origin of life with research, but many questions still remain unanswered in the broader conversation. Other questions can be answered by the laws of chemistry and physics, but questions surrounding the origin of life are best answered by reasonable extrapolations of what scientists know from observing the Earth and its solar system. Origin of Life: What Everyone Needs to Know (R) is a comprehensive scientific guide on the origin of life. David W. Deamer sets out to answer the top forty questions about the origin of life, including: Where do the atoms of life come from? How old is Earth? What was the Earth like before life originated? Where does water come from? How did evolution begin? After he provides the informational answer for each question, there is a follow-up: How do we know? This question expands the horizon of the whole book, and provides scientific reasoning and explanations for hypotheses surrounding the origin of life. How scientists come to their conclusions and why we can trust these answers is an important question, and Deamer provides answers to each big question surrounding the origin of life, from what it is to why we should be curious.
An extremely well-organized, conceptually clear, empirically informed, and carefully argued volume...What makes this contribution special is the invigorating infusion of a wealth of principles and knowledge derived from evolutionary biology, neurophysiology, and cognitive science...The chapters provide abundant material for animated discussion.'' --- Evolution and Human Behavior, September 1997 When engaging in laboratory and field studies, researchers have an extensive set of implicit assumptions that justifies their research. However, these assumptions are rarely made explicit either to the researchers themselves, to their colleagues, or to the public. In this fascinating volume, the author gives insight into these underlying beliefs that scientists have regarding moral and biological issues involved in human life-such as decisions that influence reproductive practices, the termination of life, and the pursuit of biomedical research. He then uses this descriptive base to develop an ethic based on rational liberalism. His arguments stem from the thinking of biologists, moral philosophers, cognitive scientists, and social and developmental psychologists.
A New York Times Notable Book of 2020 'Bracing and enlightening' Science Culture is something exclusive to human beings, isn't it? Not so, says intrepid researcher Carl Safina. Becoming Wild reveals the rich cultures that survive in some of Earth's remaining wild places. By showing how sperm whales, scarlet macaws and chimpanzees teach and learn, Safina offers a fresh understanding of what is constantly going on beyond humanity, and how we're all connected. 'Becoming Wild demands that we wake up' Telegraph
This is the first book on "phylogenetic supertrees," a recent, but controversial development for inferring evolutionary trees. Rather than analyze the combined primary character data directly, supertree construction proceeds by combining the tree topologies derived from those data. This difference in strategy has allowed for the exciting possibility of larger, more complete phylogenies than are otherwise currently possible, with the potential to revolutionize evolutionarily-based research. This book provides a comprehensive look at supertrees, ranging from the methods used to build supertrees to the significance of supertrees to bioinformatic and biological research. Reviews of many the major supertree methods are provided and four new techniques, including a Bayesian implementation of supertrees, are described for the first time. The far-reaching impact of supertrees on biological research is highlighted both in general terms and through specific examples from diverse clades such as flowering plants, even-toed ungulates, and primates. The book also critically examines the many outstanding challenges and problem areas for this relatively new field, showing the way for supertree construction in the age of genomics. Interdisciplinary contributions from the majority of the leading authorities on supertree construction in all areas of the bioinformatic community (biology, computer sciences, and mathematics) will ensure that this book is a valuable reference with wide appeal to anyone interested in phylogenetic inference.
The past decade has witnessed an explosion of our knowledge on the structure, coding capacity and evolution of the genomes of the two DNA-containing cell organelles in plants: chloroplasts (plastids) and mitochondria. Comparative genomics analyses have provided new insights into the origin of organelles by endosymbioses and uncovered an enormous evolutionary dynamics of organellar genomes. In addition, they have greatly helped to clarify phylogenetic relationships, especially in algae and early land plants with limited morphological and anatomical diversity. This book, written by leading experts, summarizes our current knowledge about plastid and mitochondrial genomes in all major groups of algae and land plants. It also includes chapters on endosymbioses, plastid and mitochondrial mutants, gene expression profiling and methods for organelle transformation. The book is designed for students and researchers in plant molecular biology, taxonomy, biotechnology and evolutionary biology.
ONE OF AMAZON'S TOP 100 BOOKS OF 2014 Neanderthal Man tells the story of geneticist Svante Paabo's mission to answer this question: what can we learn from the genomes of our closest evolutionary relatives? Beginning with the study of DNA in Egyptian mummies in the early 1980s and culminating in the sequencing of the Neanderthal genome in 2010, Neanderthal Man describes the events, intrigues, failures, and triumphs of these scientifically rich years through the lens of the pioneer and inventor of the field of ancient DNA. We learn that Neanderthal genes offer a unique window into the lives of our hominid relatives and may hold the key to unlocking the mystery of why humans survived while Neanderthals went extinct. Paabo's findings have not only redrawn our family tree, but recast the fundamentals of human history,the biological beginnings of fully modern Homo sapiens , the direct ancestors of all people alive today.
Papers presented at the 20th meeting of the International Ornithological Congress held in New Zealand, December 1990 emphasizing New Zealand and the southern Pacific Ocean. Topics include: a summary of ornithological work in New Zealand, enemy recognition and response, parasitism and sexual selectio
This unique reference offers a discussion of the social and legal history behind the ongoing evolution versus creationism controversy. Evolution in the Courtroom: A Reference Guide chronicles the legal history of the evolution/creation debate sparked by Charles Darwin's publication On the Origin of Species by Means of Natural Selection in 1859. The first seven chapters provide a detailed historical overview of the debate, reviewing all of the major court cases with particular emphasis on the infamous Scopes "Monkey Trial" which pitted fundamentalist William Jennings Bryan against ACLU defense attorney Clarence Darrow, and became the standard to which all subsequent evolution trails have been compared. Ensuing discussions of the rise and fall of creationism as a science and the failure of "balanced treatment" in public schools culminate in a summary of skirmishes over the last decade. Profiles of scientists, politicians, clergy, and other influential people from Galileo to Frank White, the Arkansas governor who signed the equal time law without ever reading it, reveal fascinating facts and perspectives on both sides of the controversy. Detailed chronology of the history of the debate from Aristotle in 310 B.C. to the U.S. Senate's adoption of "Sense of the Senate" in June 2002 Biographies of 172 key individuals on both sides of the controversy, including Leona Wilson, who initiated the first lawsuit by creationists An edited collection of the eight principal court decisions, including Mclean v. Arkansas and Segraves v. State of California Photographs and illustrations of influential people like Herbert Spencer, who coined the terms "evolution" and "survival of the fittest"
Current Ornithology publishes authoritative, up-to-date, scholarly reviews of topics selected from the full range of current research in avian biology. Topics cover the spectrum from the molecular level of organization to population biology and community ecology. The series seeks especially to review (1) fields in which an abundant recent literature will benefit from synthesis and organization, or (2) newly emerging fields that are gaining recognition as the result of recent discoveries or shifts in perspective, or (3) fields in which students of vertebrates may benefit from comparisons of birds with other classes. All chapters are invited, and authors are chosen for their leadership in the subjects under review.
This volume provides insight into gibbon diet and community ecology, the mating system and reproduction, and conservation biology, all topics which represent areas of substantial progress in understanding socio-ecological flexibility and conservation needs of the hylobatid family. This work analyzes hylobatid evolution by synthesizing recent and ongoing studies of molecular phylogeny, morphology, and cognition in a framework of gibbon and siamang evolution. With its clearly different perspective, this book is written to be read, referenced, and added to the bookshelves of scientists, librarians, and the interested public.
How did life begin on the early Earth? We know that life today is driven by the universal laws of chemistry and physics. By applying these laws over the past ?fty years, en- mous progress has been made in understanding the molecular mechanisms that are the foundations of the living state. For instance, just a decade ago, the ?rst human genome was published, all three billion base pairs. Using X-ray diffraction data from crystals, we can see how an enzyme molecule or a photosynthetic reaction center steps through its catalytic function. We can even visualize a ribosome, central to all life, translate - netic information into a protein. And we are just beginning to understand how molecular interactions regulate thousands of simultaneous reactions that continuously occur even in the simplest forms of life. New words have appeared that give a sense of this wealth of knowledge: The genome, the proteome, the metabolome, the interactome. But we can't be too smug. We must avoid the mistake of the physicist who, as the twentieth century began, stated con?dently that we knew all there was to know about physics, that science just needed to clean up a few dusty corners. Then came relativity, quantum theory, the Big Bang, and now dark matter, dark energy and string theory. Similarly in the life sciences, the more we learn, the better we understand how little we really know. There remains a vast landscape to explore, with great questions remaining.
