inevitability of life s generation and evolution i e Why did life generate Why does life evolve Following an introduction to the problem the hypothesis Darwinian Evolution of Molecules is proposed which explains how when and where life was instigated through successive chemical reactions and the survival of selected molecules The individual processes described are all scientifically reasonable being verifiable by experiment The hypothesis is supported by extensive reference to the scientific literature published in academic journals including some experimental reports from the author s own research group The readers of this book will learn that the decreasing temperature of the early Earth led to a reduction in its entropy inducing the Earth s materials to order which entailed ordering of the light elements as organic molecules with subsequent further ordering i e evolution to systems that can be considered alive i e life Researchers and students as well as the non-academic audience interested in the interdisciplinary problem of the origin of life will find suggestions and possible approaches to the scientific and conceptual problems they may be facingApes and Human Evolution
Par Russell H. Tuttle. 2014
In this masterwork, Russell H. Tuttle synthesizes a vast research literature in primate evolution and behavior to explain how apes…
and humans evolved in relation to one another, and why humans became a bipedal, tool-making, culture-inventing species distinct from other hominoids. Along the way, he refutes the influential theory that men are essentially killer apes--sophisticated but instinctively aggressive and destructive beings. Situating humans in a broad context, Tuttle musters convincing evidence from morphology and recent fossil discoveries to reveal what early primates ate, where they slept, how they learned to walk upright, how brain and hand anatomy evolved simultaneously, and what else happened evolutionarily to cause humans to diverge from their closest relatives. Despite our genomic similarities with bonobos, chimpanzees, and gorillas, humans are unique among primates in occupying a symbolic niche of values and beliefs based on symbolically mediated cognitive processes. Although apes exhibit behaviors that strongly suggest they can think, salient elements of human culture--speech, mating proscriptions, kinship structures, and moral codes--are symbolic systems that are not manifest in ape niches. This encyclopedic volume is both a milestone in primatological research and a critique of what is known and yet to be discovered about human and ape potential.Quantifying the Evolution of Early Life
Par James D. Schiffbauer, Marc Laflamme, Stephen Q. Dornbos. 2010
This volume provides a detailed description of a wide range of numerical, statistical or modeling techniques and novel instrumentation separated…
into individual chapters written by paleontologists with expertise in the given methodology. Each chapter outlines the strengths and limitations of specific numerical or technological approaches, and ultimately applies the chosen method to a real fossil dataset or sample type. A unifying theme throughout the book is the evaluation of fossils during the prologue and epilogue of one of the most exciting events in Earth History: the Cambrian radiation.Early Miocene Paleobiology in Patagonia
Par Sergio F. Vizcaíno, Richard F. Kay, M. Susana Bargo. 2012
Coastal exposures of the Santa Cruz Formation in southern Patagonia have been a fertile ground for recovery of Early Miocene…
vertebrates for more than 100 years. This volume presents a comprehensive compilation of important mammalian groups which continue to thrive today. It includes the most recent fossil finds as well as important new interpretations based on 10 years of fieldwork by the authors. A key focus is placed on the paleoclimate and paleoenvironment during the time of deposition in the Middle Miocene Climatic Optimum (MMCO) between 20 and 15 million years ago. The authors present the first reconstruction of what climatic conditions were like and present important new evidence of the geochronological age, habits and community structures of fossil bird and mammal species. Academic researchers and graduate students in paleontology, paleobiology, paleoecology, stratigraphy, climatology and geochronology will find this a valuable source of information about this fascinating geological formation.Giants of the Lost World: Dinosaurs and Other Extinct Monsters of South America
Par Donald R Prothero. 2016
More than a hundred years ago, Sir Arthur Conan Doyle wrote a novel called The Lost World with the exciting…
premise that dinosaurs and other prehistoric beasts still ruled in South America. Little did Conan Doyle know, there were terrifying monsters in South America--they just happened to be extinct. In fact, South America has an incredible history as a land where many strange creatures evolved and died out. In his book Giants of the Lost World: Dinosaurs and Other Extinct Monsters of South America, Donald R. Prothero uncovers the real science and history behind this fascinating story. The largest animal ever discovered was the huge sauropod dinosaur Argentinosaurus, which was about 130 feet long and weighed up to 100 tons. The carnivorous predator Giganotosaurus weighed in at more than 8 tons and measured more than 47 feet long, dwarfing the T. rex in comparison. Gigantic anacondas broke reptile records; possums evolved into huge saber-toothed predators; and ground sloths grew larger than elephants in this strange, unknown land. Prothero presents the scientific details about each of these prehistoric beasts, provides a picture of the ancient landscapes they once roamed, and includes the stories of the individuals who first discovered their fossils for a captivating account of a lost world that is stranger than fiction.Applications of Palaeontology
Par Robert Wynn Jones. 2011
Palaeontology, the scientific study of fossils, has developed from a descriptive science to an analytical science used to interpret relationships…
between earth and life history. This book provides a comprehensive and thematic treatment of applied palaeontology, covering the use of fossils in the ordering of rocks in time and in space, in biostratigraphy, palaeobiology and sequence stratigraphy. Robert Wynn Jones presents a practical workflow for applied palaeontology, including sample acquisition, preparation and analysis, and interpretation and integration. He then presents numerous case studies that demonstrate the applicability and value of the subject to areas such as petroleum, mineral and coal exploration and exploitation, engineering geology and environmental science. Specialist applications outside of the geosciences (including archaeology, forensic science, medical palynology, entomopalynology and melissopalynology) are also addressed. Abundantly illustrated and referenced, Applications of Palaeontology provides a user-friendly reference for academic researchers and professionals across a range of disciplines and industry settings.Evolution of South American Mammalian Predators During the Cenozoic: Paleobiogeographic and Paleoenvironmental Contingencies

4400 million years Starting with the Precambrian rocks that hold clues to the origins of life and the development of an oxygenated atmosphere it goes on to cover the warm seas volcanism and episodes of mountain building which formed the eastern third of the Australian continent This illuminating history details the breakup of the supercontinents Rodinia and Gondwana the times of previous glaciations the development of climates and landscapes in modern Australia and the creation of the continental shelves and coastlines Separate chapters cover the origin of the Great Barrier Reef the basalts in Eastern Australia and the geology of the Solar System This second edition features two new chapters covering the evolution of life on Earth while emphasising the fossil record in Australia and providing a geological perspective on climate change From Uluru to the Great Dividing Range from earthquakes to dinosaurs from sapphires to the stars The Geology of Australia is a comprehensive exploration of the timeless forces that have shaped this continentTikal
Par Vernon L. Scarborough, David L. Lentz, David L. Lentz Nicholas P. Dunning, Nicholas P. Dunning. 2015
The primary theoretical question addressed in this book focuses on the lingering concern of how the ancient Maya in the…
northern Petén Basin were able to sustain large populations in the midst of a tropical forest environment during the Late Classic period. This book asks how agricultural intensification was achieved and how essential resources, such as water and forest products, were managed in both upland areas and seasonal wetlands, or bajos. All of these activities were essential components of an initially sustainable land use strategy that eventually failed to meet the demands of an escalating population. This spiraling disconnect with sound ecological principles undoubtedly contributed to the Maya collapse. The book's findings provide insights that broaden the understanding of the rise of social complexity - the expansion of the political economy, specifically - and, in general terms, the trajectory of cultural evolution of the ancient Maya civilization.The Vegetation of Antarctica through Geological Time

time and also plays a key role in reconstructing past configurations of the continents and associated climatic conditions. This book provides the only detailed overview of the development of Antarctic vegetation from the Devonian period to the present day, presenting Earth scientists with valuable insights into the break up of the ancient supercontinent of Gondwana. Details of specific floras and ecosystems are provided within the context of changing geological, geographical and environmental conditions, alongside comparisons with contemporaneous and modern ecosystems. The authors demonstrate how palaeobotany contributes to our understanding of the palaeoenvironmental changes in the southern hemisphere during this period of Earth history. The book is a complete and up-to-date reference for researchers and students in Antarctic palaeobotany and terrestrial palaeoecology.From Clone to Bone
Par Robert J. Asher, Johannes Müller. 2012
Since the 1980s, a renewed understanding of molecular development has afforded an unprecedented level of knowledge of the mechanisms by…
which phenotype in animals and plants has evolved. In this volume, top scientists in these fields provide perspectives on how molecular data in biology help to elucidate key questions in estimating paleontological divergence and in understanding the mechanisms behind phenotypic evolution. Paleobiological questions such as genome size, digit homologies, genetic control cascades behind phenotype, estimates of vertebrate divergence dates, and rates of morphological evolution are addressed, with a special emphasis on how molecular biology can inform paleontology, directly and indirectly, to better understand life's past. Highlighting a significant shift towards interdisciplinary collaboration, this is a valuable resource for students and researchers interested in the integration of organismal and molecular biology.Rereading the Fossil Record: The Growth of Paleobiology as an Evolutionary Discipline
Par David Sepkoski. 2012
Rereading the Fossil Record presents the first-ever historical account of the origin, rise, and importance of paleobiology, from the mid-nineteenth…
century to the late 1980s. Drawing on a wealth of archival material, David Sepkoski shows how the movement was conceived and promoted by a small but influential group of paleontologists and examines the intellectual, disciplinary, and political dynamics involved in the ascendency of paleobiology. By tracing the role of computer technology, large databases, and quantitative analytical methods in the emergence of paleobiology, this book also offers insight into the growing prominence and centrality of data-driven approaches in recent science.Applications of Paleoenvironmental Techniques in Estuarine Studies (Developments in Paleoenvironmental Research #Volume 20)

Par David J. Bottjer. 1955
Paleoecology is a discipline that uses evidence from fossils to provide an understanding of ancient environments and the ecological history…
of life through geological time. This text covers the fundamental approaches that have provided the foundation for present paleoecological understanding, and outlines new research areas in paleoecology for managing future environmental and ecological change. Topics include the use of actualism in paleoecology, development of paleoecological models for paleoenvironmental reconstruction, taphonomy and exceptional fossil preservation, evolutionary paleoecology and ecological change through time, and conservation paleoecology. Data from studies of invertebrates, vertebrates, plants and microfossils, with added emphasis on bioturbation and microbial sedimentary structures, are discussed. Examples from marine and terrestrial environments are covered, with a particular focus on periods of great ecological change, such as the Precambrian-Cambrian transition and intervals of mass extinction. Readership: This book is designed for advanced undergraduates and beginning graduate students in the earth and biological sciences, as well as researchers and applied scientists in a range of related disciplines.The People's Peking Man: Popular Science and Human Identity in Twentieth-Century China
Par Sigrid Schmalzer. 2008
In the 1920s an international team of scientists and miners unearthed the richest evidence of human evolution the world had…
ever seen: Peking Man. After the communist revolution of 1949, Peking Man became a prominent figure in the movement to bring science to the people. In a new state with twin goals of crushing “superstition” and establishing a socialist society, the story of human evolution was the first lesson in Marxist philosophy offered to the masses. At the same time, even Mao’s populist commitment to mass participation in science failed to account for the power of popular culture—represented most strikingly in legends about the Bigfoot-like Wild Man—to reshape ideas about human nature. The People’s Peking Manis a skilled social history of twentieth-century Chinese paleoanthropology and a compelling cultural—and at times comparative—history of assumptions and debates about what it means to be human. By focusing on issues that push against the boundaries of science and politics,The People’s Peking Manoffers an innovative approach to modern Chinese history and the history of science.Scenes from Deep Time
Par Martin J. Rudwick. 1992
How did the earth look in prehistoric times? Scientists and artists collaborated during the half-century prior to the publication of…
Darwin's Origin of Species to produce the first images of dinosaurs and the world they inhabited. Their interpretations, informed by recent fossil discoveries, were the first efforts to represent the prehistoric world based on sources other than the Bible. Martin J. S. Rudwick presents more than a hundred rare illustrations from the eighteenth and nineteenth centuries to explore the implications of reconstructing a past no one has ever seen.Life on a Young Planet: The First Three Billion Years of Evolution on Earth
Par Andrew H. Knoll. 2003
Australopithecines, dinosaurs, trilobites--such fossils conjure up images of lost worlds filled with vanished organisms. But in the full history of…
life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty. The very latest discoveries in paleontology--many of them made by the author and his students--are integrated with emerging insights from molecular biology and earth system science to forge a broad understanding of how the biological diversity that surrounds us came to be. Moving from Siberia to Namibia to the Bahamas, Knoll shows how life and environment have evolved together through Earth's history. Innovations in biology have helped shape our air and oceans, and, just as surely, environmental change has influenced the course of evolution, repeatedly closing off opportunities for some species while opening avenues for others. Readers go into the field to confront fossils, enter the lab to discern the inner workings of cells, and alight on Mars to ask how our terrestrial experience can guide exploration for life beyond our planet. Along the way, Knoll brings us up-to-date on some of science's hottest questions, from the oldest fossils and claims of life beyond the Earth to the hypothesis of global glaciation and Knoll's own unifying concept of ''permissive ecology.'' In laying bare Earth's deepest biological roots, Life on a Young Planet helps us understand our own place in the universe--and our responsibility as stewards of a world four billion years in the making. In a new preface, Knoll describes how the field has broadened and deepened in the decade since the book's original publication.Hell Creek, Montana
