Available in PDF, EPUB and Kindle. Book excerpt: Seminar paper from the year 2010 in the subject English Language and Literature Studies - Linguistics, grade: 1,3, University of Münster (Englisches Seminar), course: Psycholinguistics, language: English, abstract: Fossilization is commonly described in SLA literature as a “phenomenon of non-progression of learning despite continuous exposure to input, adequate motivation to learn, and sufficient opportunity for practice” (Han 13). The Question behind this notion is: Are adults able to ever acquire native-like competence in an L2? And if some learners are, what does this mean with respect to a majority of learners who seem not to be (cf. Han 13)? This bifurcation of possible outcomes in learning a second language is mirrored in the large variety of terms used to describe the concept of ‘fossilization’. Among others, it is described “as ‘virtual halt’, ‘linguistic monstrosities’, ‘plateau’, ‘rigor mortis’, ‘stopping short’, ‘fossilized variation’, ‘permanent optionality’, ‘siesta’ [and] ‘endstate’”(Han 13 - 14). Such a range of labels reveals differing conceptual ideas about the topic’s nature concerning its powers of spread within the learner’s interlanguage, its finitude, reoccurring continuation and inevitableness. The terms ‘linguistic monstrosities’ and ‘fossilized variation’ rather hint at only parts of the interlanguage being affected by fossilization as opposed to the notion of a completely ‘fossilized interlanguage’. The term ‘virtual halt’ supports this idea that while some aspects seem to be fossilized others might continue to develop. Whereas the terms ‘rigor mortis’ and ‘endstate’ convey an understanding of fossilization’s lethal and final everlastingness prohibiting any further linguistic development whatsoever, the terms ‘siesta’, ‘plateau’ and ‘permanent optionality’ ,on the other hand, consider the concept to be negotiable in some sense holding an option of resuming linguistic development. In this paper I will very briefly outline some of the major stopping points in the more than three-decade evolution of the concept ‘fossilization’ and illustrate key conceptional issues. Relating to these difficulties I will look at recent voices who express the need for more comprehensive empirical research and rethinking of hitherto approaches and convictions. In doing so, the focus will also be on fossilization in relation to second language instruction.

Book excerpt: An in-depth look at the latest breakthroughs in our understanding of the material record that deep time leaves behind. Understanding the complex interplay of physical and chemical processes leading to fossilization is crucial to elucidating the 3800 million years of life on earth. And yet, the process of fossilization also leads to the loss of pivotal biological information, placing constraints on the very same understanding of ancient life it preserves. Over the last decade, however, remarkable advances in approaches, techniques, tools, and instrumentation have helped scientists to transcend these constraints by enabling high-resolution analysis of fossil material—even down to the nanoscale. Fossilization provides a critical look at these cutting-edge innovations in the science of fossil preservation and provides a road map for future research. Drawing from the fields of paleontology, organic and inorganic chemistry, microbiology, and high-resolution imaging and analysis, and spanning the diversity of life from plants to vertebrates and invertebrates, this resource details expert findings on • fossilization of hard and soft part tissues in dinosaurs • high-resolution chemical analysis of organic and inorganic tissues • arthropods preserved in amber • experimental silicification of wood • chemical defenses and color in fossil plants • confocal Raman spectroscopy • microprobe analysis • radioisotopic studies • and much more A true interdisciplinary undertaking, the book is authored by paleontologists, mineralogists, geochemists, organic chemists, microbiologists, and materials scientists who have worked together to investigate questions around substance fossilization and the limits of the fossil record. A special color section contains SEM, Raman, and other striking images of vertebrates, invertebrates, and plants. Fossilization is a trailblazing reference book for research scientists and specialists in related fields, as well as for advanced undergraduates and graduate students interested in fossilization, emerging research techniques, and fresh approaches in the analysis of plant and animal fossils.

Download or read book Fossils Phylogeny and Form written by Jonathan M. Adrain and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Species and Speciation in the Fossil Record written by Warren D. Allmon and published by University of Chicago Press. This book was released on 2016-10-05 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the species is one of the fundamental units of biological classification, there is remarkably little consensus among biologists about what defines a species, even within distinct sub-disciplines. The literature of paleobiology, in particular, is littered with qualifiers and cautions about applying the term to the fossil record or equating such species with those recognized among living organisms. In Species and Speciation in the Fossil Record, experts in the field examine how they conceive of species of fossil animals and consider the implications these different approaches have for thinking about species in the context of macroevolution. After outlining views of the Modern Synthesis of evolutionary disciplines and detailing the development within paleobiology of quantitative methods for documenting and analyzing variation within fossil assemblages, contributors explore the challenges of recognizing and defining species from fossil specimens—and offer potential solutions. Addressing both the tempo and mode of speciation over time, they show how with careful interpretation and a clear species concept, fossil species may be sufficiently robust for meaningful paleobiological analyses. Indeed, they demonstrate that the species concept, if more refined, could unearth a wealth of information about the interplay between species origins and extinctions, between local and global climate change, and greatly deepen our understanding of the evolution of life.
Download or read book Fossils and Evolution written by Thomas Stainforth Kemp and published by Oxford University Press, USA. This book was released on 1999-01-01 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is about the ideas, methodology and scope of contemporary palaeobiology, rather than a comprehensive, detailed survey of the factual basis of the subject. It addresses the issue of how on the one hand evolutionary theory is necessary for interpretation of the fossil record, and yet on the other the fossils themselves can contribute to evolutionary theory. This is shown not to be the circular argument between pattern and process sometimes alleged, but a matter of understanding carefully the interrelationship between palaeontological and neontological evidence. The book is organised into two sections. Part 1 consists of four chapters outlining the principles, namely: the nature of the pattern/process relationship, taxonomic methods and the analysis of pattern, evolutionary theory and the analysis of process and the nature of incompleteness of the fossil record and what to do about it. Armed with these principles and methods, Part 2 is devoted to the five centralareas of contemporary research in evolutionary palaeobiology. These are: fossils and phylogenetic inference; the mechanism of speciation; taxonomic turnover on the geological time-scale; mass-extinctions; the origin of new higher taxa. In each case the nature of the questions and the relevant kinds of evidence, including such new sources as molecular sequence data and stable isotope ratios where appropriate, are reviewed. The extent to which palaeobiology has, and has not yet, contributedto providing the sought after answers is made clear.
Download or read book Rereading the Fossil Record written by David Sepkoski and published by University of Chicago Press. This book was released on 2015-03-05 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Genes Fossils and Behaviour written by Peter Donnelly and published by IOS Press. This book was released on 2001 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the basic pattern of hominid evolution is well documented, the recent evolutionary history of homo sapiens is less clear. Application of molecular genetics techniques has great potential for resolving issues over this period, but as the complexity of such data increases, the quantitative methods used for its analysis are becoming more important. This phase is also one of the richest for biological and behavioural evidence derived from both fossils and archaeology. The book will contain expository and state-of-the-art research contributions from experts in these diverse areas, covering data and its interpretation, and experimental and analytical techniques.
Download or read book Systematics and the Fossil Record written by Andrew B. Smith and published by John Wiley & Sons. This book was released on 2009-07-15 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new text sets out to establish the key role played by systematics in deciphering patterns of evolution from the fossil record. It begins by considering the nature of the species in the fossil record and then outlines recent advances in the methodology used to establish phylogenetics relationships, stressing why fossil evidence can be crucial. The way species are grouped into higher taxa, and how this affects their utility in evolutionary studies is also discussed. Because the fossil record abounds with sampling and preservational biases, the book emphasizes that observed patterns can rarely be taken at face value. It is argued that evolutionary trees, constructed from combining phylogenetic and biostratigraphic data, provide the best approach for investigating patterns of evolution through geologic time. The only integrated text covering the study of evolutionary patterns from a phylogenetic stance.

Download or read book Fossils written by Niles Eldredge and published by White Lion Publishing. This book was released on 1991 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this fascinating exploration of the fossil record, Niles Eldredge overturns the traditional view of evolution as a slow and inevitable process, and he shows that lifeforms generally do not evolve to any significant degree until after massive extinction. This rhythm of life--a concept developed by Eldredge and Stephen Jay Gould known as punctuated equilibria in evolution-- is revealed by the fossilized remains of the earth's ancient flora and fauna. Distinguished photographer Murray Alcosser augments Eldredge's text with 160 luminous color plates illustrating more than 250 different fossil specimens. In this new paperback edition, Fossils becomes an accessible text with appeal to a broad audience, including natural history readers and students.

Available in PDF, EPUB and Kindle. Book excerpt: The case history approach has an impressive record of success in a variety of disciplines. Collections of case histories, casebooks, are now widely used in all sorts of specialties other than in their familiar appli cation to law and medicine. The case method had its formal beginning at Harvard in 1871 when Christopher Lagdell developed it as a means of teaching. It was so successful in teaching law that it was soon adopted in medical education, and the collection of cases provided the raw material for research on various diseases. Subsequently, the case history approach spread to such varied fields as business, psychology, management, and economics, and there are over 100 books in print that use this approach. The idea for a series of Casehooks in Earth Science grew from my experience in organizing and editing a collection of examples of one variety of sedimentary deposits. The prqject began as an effort to bring some order to a large number of descriptions of these deposits that were so varied in presentation and terminology that even specialists found them difficult to compare and analyze. Thus, from the beginning, it was evident that something more than a simple collection of papers was needed. Accordingly, the nearly fifty contributors worked together with George de Vries Klein and me to establish a standard format for presenting the case histories.

Book excerpt: Why and How: Some Problems and Methods in Historical Biology discusses an overall approach to the study of fossils combined with paleontology. This book is divided into six chapters. Chapter 1 consists of a few examples of studies of the fossil record, focusing on its adequacy, and ways of looking at and representing some of its aspects. The most basic aspects of study of the fossil record such as the examination, description, and illustration of the morphology of fossils are described in Chapter 2. Chapter 3 focuses on paleoecology and faunal analysis, while Chapter 4 emphasizes some of the aspects of phylogenetic principles and eclectic taxonomic theory. The essential apparatus for zoological studies that include biometrical statistics both in concepts and in measures are deliberated in Chapter 5. The last chapter deliberates the geographic distribution of organisms. This publication is a good source for paleontologists and biologists interested in historical biology.

Download or read book Exceptional Fossil Preservation written by David J. Bottjer and published by Columbia University Press. This book was released on 2002 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most nonscientists are usually aware of fossils, and it is commonly believed that they are extremely rare. In fact, fossils are exceptionally common in many sedimentary rocks and are used extensively in geology for age dating, interpretation of ancient environments, and the discovery of natural resources. However, there is another type of fossil deposit that is truly rare. These rare fossil deposits, called Lagerstätten, preserve the remains of the soft tissues or the articulated skeletal remains of ancient creatures in truly astonishing fine detail. Some of these deposits are world-famous, such as the Burgess Shale, or Solnhofen but there are others dating from many different geological eras from the Paleozoic, up to the Eocene. Recently, a concerted effort has been made to understand the overall significance of these rare fossil deposits. Whereas in the past these deposits were considered novelties, modern researchers are trying to understand what they can tell us about ancient life and environments. New sophisticated techniques (including image and geochemical analyses) are providing enormous new contributions to our knowledge of Lagerstätten sites and to paleobiology in general. This volume describes many of the most famous Lagerstätten locations worldwide and is complete with over 70 superb halftones showing some of these exotic fossils in all their glory. Paleontologists are beginning to understand why such deposits occur, how they have varied since the advent of marine metazoan life, and how their presence effects our understanding of the evolution of life in the Earth's oceans. In this way, the study of Lagerstätten continues to move towards the mainstream of paleobiological, biological, and geological research, and away from its former status as the examination of mere curiosities. All those interested in these beautiful and sometimes enigmatic deposits will want to own this book.
