In Pursuit of Early Mammals presents the history of the mammals that lived during the Mesozoic era, the time when dinosaurs ruled the Earth, and describes their origins, anatomy, systematics, paleobiology, and distribution. It also tells the story of the author, a world-renowned specialist on these animals, and the other prominent paleontologists who have studied them. Zofia Kielan-Jaworowska was the first woman to lead large-scale paleontological expeditions, including eight to the Gobi Desert in Mongolia, which brought back important collections of dinosaur, early mammal, and other fossils. She shares the difficulties and pleasures encountered in finding rare fossils and describes the changing views on early mammals made possible by these discoveries.
The first book of its kind, In Quest of Great Lakes Ice Age Vertebrates details the Ice Age fishes, amphibians, reptiles, birds and mammals in the provinces and states surrounding the Great Lakes. Holman's work begins with definitions of concepts and terms for the general audience and a general discussion of how the last ice age, the Pleistocene Epoch, affected our physical and biological world. Methods employed and tools used in the collection of vertebrate fossils, as well as ethics and protocol in the maintenance of a useful collection follow, coupled with details of each animal's structure, habits, habitats, and ecological importance. The heart of the book is a species-by-species account of the Pleistocene vertebrates of the region, followed by an examination of the compelling problems of the Pleistocene relative to faunal interpretations, including overall ecological makeup of the region's fauna, vertebrate range adjustment that occurred in the region, Pleistocene extinction effects on the animals of the region, the aftermath of the Ice Age, and a look at what the future may hold for the region.
How Creationists Built the Campaign against Evolution
This volume examines how Saving Our Lives Hear Our Truths, or SOLHOT, a radical youth intervention, provides a space for the creative performance and expression of Black girlhood and how this creativity informs other realizations about Black girlhood and womanhood. Founded in 2006 and co-organized by the author, SOLHOT is an intergenerational collective organizing effort that celebrates and recognizes Black girls as producers of culture and knowledge. Girls discuss diverse expressions of Black girlhood, critique the issues that are important to them, and create art that keeps their lived experiences at its center. Drawing directly from her experiences in SOLHOT, Ruth Nicole Brown argues that when Black girls reflect on their own lives, they articulate radically unique ideas about their lived experiences. She documents the creative potential of Black girls and women who are working together to advance original theories, practices, and performances that affirm complexity, interrogate power, and produce humanizing representation of Black girls' lives. Emotionally and intellectually powerful, this book expands on the work of Black feminists and feminists of color and breaks intriguing new ground in Black feminist thought and methodology.
Olfactory Perception from Neurobiology to Behavior
Written by a neurobiologist and a psychologist, this volume presents a new theory of olfactory perception. Drawing on research in neuroscience, physiology, and ethology, Donald A. Wilson and Richard J. Stevenson address the fundamental question of how we navigate through a world of chemical encounters and provide a compelling alternative to the "reception-centric" view of olfaction. The major research challenge in olfaction is determining how the brain discriminates one smell from another. Here, the authors hold that olfaction is generally not a simple physiochemical process, but rather a plastic process that is strongly tied to memory. They find the traditional approach—which involves identifying how particular features of a chemical stimulus are represented in the olfactory system—to be at odds with historical data and with a growing body of neurobiological and psychological evidence that places primary emphasis on synthetic processing and experiential factors. Wilson and Stevenson propose that experience and cortical plasticity not only are important for traditional associative olfactory memory but also play a critical, defining role in odor perception and that current views are insufficient to account for current and past data. The book includes a broad comparative overview of the structure and function of olfactory systems, an exploration into the mechanisms of odor detection and olfactory perception, and a discussion of the implications of the authors' theory. Learning to Smell will serve as an important reference for workers within the field of chemical senses and those interested in sensory processing and perception.
Revealing the Unseen Lives of Plants and Animals
Have you ever wondered what left behind those prints and tracks on the seashore, or what made those marks or dug those holes in the dunes? Life Traces of the Georgia Coast is an up-close look at these traces of life and the animals and plants that made them. It tells about the how the tracemakers lived and how they interacted with their environments. This is a book about ichnology (the study of such traces), a wonderful way to learn about the behavior of organisms, living and long extinct. Life Traces presents an overview of the traces left by modern animals and plants in this biologically rich region; shows how life traces relate to the environments, natural history, and behaviors of their tracemakers; and applies that knowledge toward a better understanding of the fossilized traces that ancient life left in the geologic record. Augmented by numerous illustrations of traces made by both ancient and modern organisms, the book shows how ancient trace fossils directly relate to modern traces and tracemakers, among them, insects, grasses, crabs, shorebirds, alligators, and sea turtles. The result is an aesthetically appealing and scientifically accurate book that will serve as both a source book for scientists and for anyone interested in the natural history of the Georgia coast.
Origin, Evolution, and Diversity
In this unique book, Peter S. Ungar tells the story of mammalian teeth from their origin through their evolution to their current diversity. Mammal Teeth traces the evolutionary history of teeth, beginning with the very first mineralized vertebrate structures half a billion years ago. Ungar describes how the simple conical tooth of early vertebrates became the molars, incisors, and other forms we see in mammals today. Evolutionary adaptations changed pointy teeth into flatter ones, with specialized shapes designed to complement the corresponding jaw. Ungar explains tooth structure and function in the context of nutritional needs. The myriad tooth shapes produced by evolution offer different solutions to the fundamental problem of how to squeeze as many nutrients as possible out of foods. The book also highlights Ungar's own path-breaking studies that show how microwear analysis can help us understand ancient diets. The final part of the book provides an in-depth examination of mammalian teeth today, surveying all orders in the class, family by family. Ungar describes some of the more bizarre teeth, such as tusks, and the mammal diversity that accompanies these morphological wonders. Mammal Teeth captures the evolution of mammals, including humans, through the prism of dental change. Synthesizing decades of research, Ungar reveals the interconnections among mammal diet, dentition, and evolution. His book is a must-read for paleontologists, mammalogists, and anthropologists.
John Avise is one of the most distinguished evolutionary biologists of our time. His groundbreaking work with mitochondrial DNA created the entire discipline of phylogeography and his work on the Pleistocene refugia hypothesis redirected scientific thinking about patterns of distribution. Spanning a remarkable thirty-five-year career, the essays gathered here were rewritten from his previously published articles and represent the first single-volume collection of Avise's work. Moving through various questions in evolutionary biology, these eclectic essays reveal Avise's unique perspectives on major topics in the field. From how to define a species to the folly of faulty applications of cladistics to connections between conservation and evolutionary biology, On Evolution takes the reader on a personal journey into the mind of one of the world's leading evolutionists.
Growing Up Evolutionist in an Evolving World
In this book, Rudolf A. Raff reaches out to the scientifically queasy, using his life story and his growth as a scientist to illustrate why science matters, especially at a time when many Americans are both suspicious of science and hostile to scientific ways of thinking. Noting that science has too often been the object of controversy in school curriculums and debates on public policy issues ranging from energy and conservation to stem-cell research and climate change, Raff argues that when the public is confused or ill-informed, these issues tend to be decided on religious, economic, and political grounds that disregard the realities of the natural world. Speaking up for science and scientific literacy, Raff tells how and why he became an evolutionary biologist and describes some of the vibrant and living science of evolution. Once We All Had Gills is also the story of evolution writ large: its history, how it is studied, what it means, and why it has become a useful target in a cultural war against rational thought and the idea of a secular, religiously tolerant nation.
A Variorum Text
The theories propounded by Charles Darwin in The Origin of Species have had a profound and revolutionary effect, not only on biology but also on philosophy, history, and theology. His concept of natural selection has created eruptive disputes among scientists and religious leaders of his time and ours. The phenomenal importance of his brilliant work is universally recognized, but the present volume marks the first scholarly attempt to compile a complete variorum edition of The Origin of Species, covering all of the extensive variants in the six texts published between 1859 and 1872.
Darwin's changes were extensive. His book grew by a third as he rewrote many passages four or five times, and in this edition Morse Peckham has recorded every one of those changes. A book of such distinctive dimensions, on a subject of such profound importance, will be of intense interest to historians of biology, evolution, science, literature, and cultural development. It will be an invaluable aid to the clarification and full comprehension of this complex and renowned scientific classic.
Gesture, Sign, and the Sources of Language
In the ongoing debate about evolution, scholars frequently argue either the perspective that humans stand as the end product of a deliberate process or that they derive from a series of random acts of natural selection. David F. Armstrong’s new book Original Signs embraces the Darwinian concept of natural selection and extends it to apply to the formation of language. While most current linguistic theory envisions language as a system for translating the contents of the mind into linear strings of arbitrary symbols, Armstrong asserts that this model does not characterize signed languages. He shows that language is inherently a multichannel activity, of which the two primary channels are auditory and visual. Original Signs employs a more expansive notion of language that takes into account the full range of human communicative behavior. By making no strict separation between language and gesture, this thought-provoking work reveals that the use by deaf people of signs to create a fully formed language is also a natural facet of communication development for hearing people. Armstrong explores the influences of Plato and Descartes on modern linguistics, and delineates the theories of earlier anthropological linguists Edward Sapir and Benjamin Lee Whorf, who thought of language as natural experiments connected to individual cultures. This exceptional work of scholarship methodically demonstrates that the intricacies of how languages develop, whether they depend upon words or signs, and that the complexity among languages that contact one another cannot be accounted for by the sequential hierarchical processes previously put forth by linguists and logicians. Original Signs will prove to be a fascinating, watershed work invaluable to linguists, anthropologists, and all other scholars and students engaged in the search for the origin of language.
