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.
Most major recent advances in understanding the history of life on Earth have been through the study of exceptionally well preserved biotas (Fossil-Lagerstatten). These are windows on the history of life on Earth and can provide a fairly complete picture of the evolution of ecosystems through time. This book follows the success of Evolution of Fossil Ecosystems by the same authors which covered Fossil-Lagerstatten around the world. The success of the first book prompted this new book which draws on four localities from the original book and adds another ten, all located in North America. Following an introduction to Fossil-Lagerstatten, each chapter deals with a single fossil locality. Each chapter contains a brief introduction placing the Lagerstatte in an evolutionary context; there then follows a history of study of the locality; the background sedimentology, stratigraphy and palaeoenvironment; a description of the biota; discussion of the palaeoecology, and a comparison with other Lagerstatten of a similar age and/or environment. At the end of the book is an Appendix listing museums in which to see exhibitions of fossils from each locality and suggestions for visiting the sites.
In the present book the Paleogene fossil record of birds is detailed for the first time on a worldwide scale. I have developed the idea for such a project for several years, and think that it is an appropriate moment to present a summary of our c- rent knowledge of the early evolution of modern birds. Meanwhile not only is there a confusing diversity of fossil taxa, but also significant progress has been made concerning an understanding of the higher-level phylogeny of extant birds. Hypotheses which were not considered even a decade ago are now well supported by independent analyses of different data. In several cases these group together morphologically very different avian groups and allow a better understanding of the mosaic character distribution found in Paleogene fossil birds. The book aims at bringing some of this information together, and many of the following data are based on first-hand examination of fossil specimens.
Increasing rate of species extinction in the present day will lead to a huge biodiversity crisis; eventually, this will lead to the paucity of non-renewable resources of energy making our Earth unsustainable in future. To save our mother planet from this crisis, studies need to be performed to discover abundant new fossil sites on Earth for continued access to oil-rich locations. Most importantly, a holistic approach is necessary in solving the present problem of biodiversity loss. This book presents newly developed quantitative models in understanding the biodiversity, evolution and ecology of extinct organisms. This will assist future earth scientists in understanding the natural and anthropogenic causes behind biodiversity crisis and ecosystem collapse. In addition, this study would be of great interest to exploration geologists and geophysicists in potentially unraveling natural resources from our sustainable Earth.
Foraminiferal Micropaleontology for Understanding Earth's History incorporates new findings on taxonomy, classification and biostratigraphy of foraminifera. Foraminifera offer the best geochemical proxies for paleoclimate and paleoenvironment interpretation. The study of foraminifera was promoted by oil exploration due to its exceptional use in subsurface stratigraphy. A rapid technological development in the past 20 years in the field of imaging microfossils and in geochemical microanalysis have added novel information about foraminifera. Foraminiferal Micropaleontology for Understanding Earth's History builds an understanding of biology, morphology and classification of foraminifera for its varied applications. In the past two decades, a phenomenal growth has occurred in geochemical proxies in shells of foraminifera, and as a result, crucial information about past climate of the earth is achieved. Foraminifera is the most extensively used marine microfossils in deep-time reconstruction of the earth history. Its key applications are in paleoenvironment and paleoclimate interpretation, paleoceanography, and biostratigraphy to continuously improve the Geologic Time Scale.
Late Quaternary Environmental Change: Physical and Human
Perspectives
This volume reviews the meaning of taxonomic statements and considers our present knowledge regarding the number and characteristics of species among living and extinct primates, including man and his ancestors. They also examine the relationship of behaviour changes and selection pressures in evolutionary sequences. First published in 1964.
This book is the first of its kind on environmental change research devoted to monsoon-arid environment evolution history and its mechanism involved. Capturing the most prominent features of Asian climate and environmental changes, it gives a comprehensive review of the Asian Monsoon records providing evidence for spatial and temporal climatic and environmental changes across the Asian continent since the Late Cenozoic. The dynamics underlying these changes are explored based on various bio-geological records and in particular based on the evidence of loess, speleothems as well as on mammal fossils. The Asian monsoon-arid climate system which quantifies the controlling mechanisms of climate change and the way it operates in different time scales is described. Attempts to differentiate between natural change and human-induced effects, which will help guide policies and countermeasures designed to support sustainable development on the Chinese Loess Plateau and the arid west.
Fresh insights into the ongoing fascination with dinosaurs and their place in 19th century American nationalism In 1801, the first complete mastodon skeleton was excavated in the Hudson River Valley, marking the climax of a century-long debate in America and Europe over the identity of a mysterious creature known as the American Incognitum. Long before the dinosaurs were discovered and the notion of geological time acquired currency, many citizens of the new republic believed this mythical beast to be a ferocious carnivore, capable of crushing deer and elk in its "monstrous grinders." During the American Revolution, George Washington and Thomas Jefferson avidly collected its bones; for the founding fathers, its massive jaws symbolized the violence of the natural world and the emerging nation's own dreams of conquest. Paul Semonin's lively history of this icon of American nationalism focuses on the link between patriotism and prehistoric nature. From the first fist-sized tooth found in 1705, which Puritan clergyman claimed was evidence of human giants, to the scientific racialism associated with the discovery of extinct species, Semonin traces the evangelical beliefs, Enlightenment thought, and Indian myths which led the founding fathers to view this prehistoric monster as a symbol of nationhood. Semonin also sees the mystery of the mastodon in early America as a cautionary tale about the first flowering of our narcissistic fascination with a prehistoric nature ruled by ferocious carnivores. As such, American Monster offers fresh insights into the genesis of the ongoing fascination with dinosaurs.
Virtual palaeontology, the use of interactive three-dimensional digital models as a supplement or alternative to physical specimens for scientific study and communication, is rapidly becoming important to advanced students and researchers. Using non-invasive techniques, the method allows the capture of large quantities of useful data without damaging the fossils being studied "Techniques for Virtual Palaeontology" guides palaeontologists through the decisions involved in designing a virtual palaeontology workflow and gives a comprehensive overview, providing discussions of underlying theory, applications, historical development, details of practical methodologies, and case studies. Techniques covered include physical-optical tomography (serial sectioning), focused ion beam tomography, all forms of X-ray CT, neutron tomography, magnetic resonance imaging, optical tomography, laser scanning, and photogrammetry. Visualization techniques and data/file formats are also discussed in detail. Readership: aAll palaeontologists and students interested in three-dimensional visualization and analysis."New Analytical Methods in Earth and Environmental Science " Because of the plethora of analytical techniques now available, and the acceleration of technological advance, many earth scientists find it difficult to know where to turn for reliable information on the latest tools at their disposal, and may lack the expertise to assess the relative strengths or limitations of a particular technique. This new series will address these difficulties by providing accessible introductions to important new techniques, lab and field protocols, suggestions for data handling and interpretation, and useful case studies. The series represents an invaluable and trusted source of information for researchers, advanced students and applied earth scientists wishing to familiarise themselves with emerging techniques in their field.

Titles are also available in an enhanced eBook edition which may include additional features such as DOI linking, high resolution graphics and video.""
The taphonomic approach within paleontology, archaeology, and paleoanthropology continues to produce advances in understanding postmortem biochemical and morphological transformations. Conversely, advances in understanding the early and intermediate postmortem period generated in the forensic realm can and should be brought to the attention of scientists who study the historic and prehistoric past.
Delivering a synthesis of almost one hundred and fifty years of
research into the Jordan Rift Valley, this genuinely comprehensive
text presents a model explaining the tectonic evolution of this
part of the Syrian-African Rift Valley, which may affect opinions
regarding the geotectonic pattern of the entire western Levant.
Initially, this work was designed to document and study the diversification of modern mammalian groups and was quite successful and satisfying. However, as field and laboratory work continued, there began to develop a suspicion that not all of the Eocene story was being told. It became apparent that most fossil samples, especially those from the American West, were derived from similar preservational circumstances and similar depositional settings. A program was initiated to look for other potential sources of fossil samples, either from non-traditional lithologies or from geographic areas that were not typically sampled. As this program of research grew it began to demonstrate that different lithologies and different geographic areas told different stories from those that had been developed based on more typical faunal assemblages. This book is conceived as an introduction to non-traditional Eocene fossils samples, and as a place to document and discuss features of these fossil assemblages that are rare or that come from rarely represented habitats.
Central theoretical issues regarding behavioural reconstruction in human osteological research are raised in this analytical volume. Because behavioural reconstructions have become increasingly common, especially with palaeopathology, this work seeks to review the scientific basis for such an approach. For example, osteological scenarios seeking to link the onset of skeletal conditions such as osteoarthritis, dental disease, and trauma with specific behaviours in the past populations, are critically examined. Questions are also raised as to the scientific rigor of such hypotheses, the ethnohistoric evidence used to support them, and ultimately, the soundness of such claims. In addition, commentary is included that broadens the scope to include anthropology, and explains the utility of behavioural reconstructions in palaeoanthropology and the biocultural perspective as it is used in contemporary anthropology.
This study brings together decades of research on the modern natural environment of Washington's Olympic Peninsula, reviews past research on paleoenvironmental change since the Late Pleistocene, and finally presents paleoecological records of changing forest composition and fire over the last 14,000 years. The focus of this study is on the authors' studies of five pollen records from the Olympic Peninsula. Maps and other data graphics are used extensively. Paleoecology can effectively address some of these challenges we face in understanding the biotic response to climate change and other agents of change in ecosystems. First, species responses to climate change are mediated by changing disturbance regimes. Second, biotic hotspots today suggest a long-term maintenance of diversity in an area, and researchers approach the maintenance of diversity from a wide range and angles (CITE). Mountain regions may maintain biodiversity through significant climate change in 'refugia': locations where components of diversity retreat to and expand from during periods of unfavorable climate (Keppel et al., 2012). Paleoecological studies can describe the context for which biodiversity persisted through time climate refugia. Third, the paleoecological approach is especially suited for long-lived organisms. For example, a tree species that may typically reach reproductive sizes only after 50 years and remain fertile for 300 years, will experience only 30 to 200 generations since colonizing a location after Holocene warming about 11,000 years ago. Thus, by summarizing community change through multiple generations and natural disturbance events, paleoecological studies can examine the resilience of ecosystems to disturbances in the past, showing how many ecosystems recover quickly while others may not (Willis et al., 2010).
The new edition of this work includes an appendix listing criteria for the identification of ichnotaxa. It covers all aspects of tiering trace fossil diversity and ichnoguilds, and is aimed at advanced undergraduates and postgraduates in palaeoecology, paleobiology and sedimentology.
These papers show how new research in the classic areas and Germany, but particularly in Eastern Europe, is radically altering views of the stratigraphy and palaeocology of the early-middle Pleistocene period, showing that major glaciations did not begin only in the late- middle Pleistocene.
Phylogenetic analysis and morphometrics have been developed by biologists into rigorous analytic tools for testing hypotheses about the relationships between groups of species. This book applies these tools to paleontological data. The fossil record is our one true chronicle of the history of life, preserving a set of macroevolutionary patterns; thus various hypotheses about evolutionary processes can be tested in the fossil record using phylogentic analysis and morphometrics. The first book of its type, Fossils, Phylogeny, and Form will be useful in evolutionary biology, paleontology, systematics, evolutionary development, theoretical biology, biogeography, and zoology. It will also provide a practical, researcher-friendly gateway into computer-based phylogenetics and morphometrics.
If you want to know how we know what we know about dinosaurs, read this book! Steve Brusatte Startling new fossil finds are the lifeblood of modern palaeobiology. Giant sauropod dinosaur skeletons from Patagonia, dinosaurs with feathers from China, and even a tiny dinosaur tail in Burmese amber complete down to every detail of its filament-like feathers, skin, bones and mummified tail muscles inspire awe in a global audience enthralled by the idea of these great creatures walking the earth. Dinosaurs are of perennial interest to all ages, as illustrated by the huge range of dino-themed films, books and live attractions, from the enduring popularity of the Jurassic Park franchise to the success of London s immersive Dinosaurs in the Wild experience. In the past twenty years, dinosaur study has changed from natural history to testable science. New technologies have revealed secrets locked in the bones in a way nobody predicted we can now work out the colour of dinosaurs, their bite forces, speeds and parental care as well as how they came to die out.This groundbreaking book illustrates how science has replaced speculation and how our understanding of dinosaurs and their world hascompletely changed. The subject has never been so vigorous, has never changed so fast, and has never been so attractive to so many.
This book includes a collection of papers, dedicated to Tjalling Waterbolk, on various topics, including palaeobotanical and archaeological research, prehistoric settlement in the province of Drenthe and the coastal areas of Groningen and Friesland, and radiocarbon dating of archaeological samples.
New material attributable to Deltasuchus motherali, a neosuchian from the Cenomanian of Texas, provides sampling across much of the ontogeny of this species. Detailed descriptions provide information about the paleobiology of this species, particularly with regards to how growth and development affected diet. Overall snout shape became progressively wider and more robust with age, suggesting that dietary shifts from juvenile to adult were not only a matter of size change, but of functional performance as well. These newly described elements provide additional characters upon which to base more robust phylogenetic analyses. The authors provide a revised diagnosis of this species, describing the new material and discussing incidents of apparent ontogenetic variation across the sampled population. The results of the ensuing phylogenetic analyses both situate Deltasuchus within an endemic clade of Appalachian crocodyliforms, separate and diagnosable from goniopholidids and pholidosaurs, herein referred to as Paluxysuchidae. This title is also available as Open Access on Cambridge Core.
This volume is a record of the 6th International Conference on the Origins of Life and the 3rd Meeting of the International Society for the Study of the Origins of Life. The conference was held under the auspices of the Israel Academy of Sciences and Humanities at Jerusalem from June 22nd to June 27th 1980. A few weeks prior to the conference, Academician Aleksander Ivanovich Oparin passed away. Oparin, the father and founder of the study of the origins of life, proposed over 50 years ago that modern biological molecules had abidogical origins in the past, thus the beginning of life on Earth was preceded by a long period of abiogenic molecular evolution. Oparin was planning to report on his latest work in the opening session of the meeting - "Natural Selection: A Leading Factor in Transition from the Non-Living Matter to Life." This lecture will never be delivered. In Hebrew we say of those who have died "may their memory be bound with the bonds of eternal life." For Aleksander Ivanovich Oparin those words have particular significance, for surely his pioneering work will endure as long as the spirit of scientific enquiry prevails. This meeting was dedicated to the memory of Aleksander Ivanovich Oparin.
The richly fossiliferous Neogene stratigraphic sections of the Dominican Republic serve as one of only a few geological research systems in the world where morphological stasis and punctuated speciation have been investigated in multiple lineages. This research system provides unprecedented opportunities for comparative studies of evolutionary stasis and change and their environmental and ecological contexts. In this volume, a diverse group of geologists and paleobiologists collectively focus their attention on this research system, providing an updated geological framework and a series of novel studies of evolutionary stasis and change among different lineages and associated ecological communities. This collection of studies illustrates the immense potential of collaborative, multidisciplinary, and field-based paleobiological research for studies of macroevolutionary change in the fossil record. |
