What, if anything, are species? PDF Author: Brent D. Mishler
Publisher: CRC Press
ISBN: 1351645994
Category : Nature
Languages : en
Pages : 254

Book Description
This book is an extended argument for abandoning the species rank. Instead, the author proposes that the rank of "species" be replaced by a pluralistic and multi-level view. In such a view, all clades including the smallest identifiable one would be named and studied within a phylogenetic context. What are currently called "species" represent different sorts of things depending on the sort of organisms and processes being considered. This is already the case, but is not formally recognized by those scientists using the species rank in their work. Adopting a rankless taxonomy at all levels would enhance academic studies of evolution and ecology and yield practical benefits in areas of public concern such as conservation. The Open Access version of this book, available at http://www.taylorfrancis.com/books/e/9781498714549, has been made available under a Creative Commons Attribution-Non Commercial license. KEY FEATURES • Proposes the replacement of restrictive species concepts with a pluralistic view • Suggests abandoning the formal taxonomic rank of "species" • Considers zoological, botanical, and microbiological aspects of the species level • Deals with practical issues such as conservation, inventories, and field guides

The Species Problem

The Species Problem PDF Author: Richard A. Richards
Publisher: Cambridge University Press
ISBN: 1139488295
Category : Science
Languages : en
Pages : 247

Book Description
There is long-standing disagreement among systematists about how to divide biodiversity into species. Over twenty different species concepts are used to group organisms, according to criteria as diverse as morphological or molecular similarity, interbreeding and genealogical relationships. This, combined with the implications of evolutionary biology, raises the worry that either there is no single kind of species, or that species are not real. This book surveys the history of thinking about species from Aristotle to modern systematics in order to understand the origin of the problem, and advocates a solution based on the idea of the division of conceptual labor, whereby species concepts function in different ways - theoretically and operationally. It also considers related topics such as individuality and the metaphysics of evolution, and how scientific terms get their meaning. This important addition to the current debate will be essential for philosophers and historians of science, and for biologists.

Languages : en
Pages : 0

Book Description
The general notion of species is one of the most fundamental in biology. But an idea of species is also one of the most persistent unresolved obsessions of biologists, philosophers and theoreticians. This new book investigates the multifaceted problem species as a "conceptual envelope" of that notion. Contemporary conceptualists and evolutionary epistemology allow for a fresh look by analyzing the framework of history viewed as changes ordered by changing philosophical-scientific contexts. In this analysis, the species problem is characterized in a pluralistic non-trivial manner, in contrast to a more monistic "accepted view." Key Features Provides new insights into the persistent species "problem." Focuses on conceptual history and identifies pivotal landmarks in the history of the concept of species. Argues for a scientific consistency of species pluralism. Discusses the "evolving species-hood" in the context of new essentialism. Related Titles * Wilkins, J. S, et al., eds.

The Property Species

The Property Species PDF Author: Bart J. Wilson
Publisher: Oxford University Press, USA
ISBN: 0190936789
Category : Business & Economics
Languages : en
Pages : 265

Book Description
"What is property, and why does our species happen to have it? In The Property Species, Bart Wilson explores how Homo sapiens acquires, perceives, and knows the custom of property, and why it might be relevant for understanding how property works in the twenty-first century. Arguing from some hard-to-dispute facts that neither the natural sciences nor the humanities - nor the social sciences squarely in the middle - are synthesizing a full account of property, Wilson offers a cross-disciplinary compromise that is sure to be controversial: All human beings and only human beings have property in things, and at its core, property rests on custom, not rights. Such an alternative to conventional thinking contends that the origins of property lie not in food, mates, territory, or land, but in the very human act of creating, with symbolic thought, something new that did not previously exist. Integrating cognitive linguistics with the philosophy of property and a fresh look at property disputes in the common law, Wilson makes the case that symbolic-thinking humans locate the meaning of property within a thing. The provocative implications are that property - not property rights - is an inherent fundamental principle of economics, and that legal realists and the bundle of sticks metaphor are wrong about the facts regarding property. Written by an economist who marvels at the natural history of humankind, the book is essential reading for experts and any reader who has wondered why people claim things as "Mine!", and what that means for our humanity.

Species PDF Author: John S. Wilkins

ISBN: 0520945077
Category : Science
Languages : en
Pages : 321

Book Description
The complex idea of "species" has evolved over time, yet its meaning is far from resolved. This comprehensive work takes a fresh look at an idea central to the field of biology by tracing its history from antiquity to today. John S. Wilkins explores the essentialist view, a staple of logic from Plato and Aristotle through the Middle Ages to fairly recent times, and considers the idea of species in natural history—a concept often connected to reproduction. Tracing "generative conceptions" of species back through Darwin to Epicurus, Wilkins provides a new perspective on the relationship between philosophical and biological approaches to this concept. He also reviews the array of current definitions. Species is a benchmark exploration and clarification of a concept fundamental to the past, present, and future of the natural sciences.

Metaphysics and the Origin of Species

Metaphysics and the Origin of Species PDF Author: Michael T. Ghiselin
Publisher: SUNY Press
ISBN: 9780791434673
Category : Science
Languages : en
Pages : 394

Book Description
In explaining his individuality thesis, Michael T. Ghiselin provides extended discussions of such philosophical topics as definition, the reality of various kinds of groups, and how we classify traits and processes. He develops and applies the implications for general biology and other sciences and makes the case that a better understanding of species and of classification in general puts biologists and paleontologists in a much better position to understand nature in general, and such processes as extinction in particular.

Social Trust and the Management of Threatened and Endangered Species

Social Trust and the Management of Threatened and Endangered Species PDF Author: George Cvetkovich
Publisher:
ISBN:
Category : Conservation of natural resources
Languages : en
Pages : 76

Book Description
Social trust, the willingness to rely on those with formal responsibility to develop policies and make decisions, facilitates effective management of environmental issues, including wildlife management. National polls suggest that the public trusts government agencies to solve environmental problems, yet such trust is low (or non-existent) in areas of controversy, such as the protection of threatened and endangered species. This study explored the role of social trust in understanding views of threatened and endangered species management in the National Forests of southern California. The 127 participants surveyed lived in or near a National Forest or were recreational and/or other users of the National Forest. The results suggest that trust in Forest Service management of wildlife relates to perceived similarity between individual values regarding species protection and Forest Service values. Participants who believe the Forest Service shares their values have a high trust; those who believe the Forest Service does not share their values have a low trust. The most trusting tend to believe that species protection should be the primary principle guiding forest management and that the Forest Service consistently operates according to these principles. Those low in trust believe forest management should be based on the fulfillment of human needs; they perceive that the Forest Service operates inconsistently according to their values. The study suggests that social trust is a significant predictor of approval of species management practices.

Species, Species Concepts and Primate Evolution

Species, Species Concepts and Primate Evolution PDF Author: William H. Kimbel
Publisher: Springer Science & Business Media
ISBN: 1489937455
Category : Science
Languages : en
Pages : 561

Book Description
A world of categones devmd of spirit waits for life to return. Saul Bellow, Humboldt's Gift The stock-in-trade of communicating hypotheses about the historical path of evolution is a graphical representation called a phylogenetic tree. In most such graphics, pairs of branches diverge from other branches, successively marching across abstract time toward the present. To each branch is tied a tag with a name, a binominal symbol that functions as does the name given to an individual human being. On phylogenetic trees the names symbolize species. What exactly do these names signify? What kind of information is communicated when we claim to have knowledge of the following types? "Tetonius mathewzi was ancestral to Pseudotetonius ambiguus. " "The sample of fossils attributed to Homo habzlis is too variable to contain only one species. " "Interbreeding populations of savanna baboons all belong to Papio anubis. " "Hylobates lar and H. pileatus interbreed in zones of geographic overlap. " While there is nearly universal agreement that the notion of the speczes is fundamental to our understanding of how evolution works, there is a very wide range of opinion on the conceptual content and meaning of such particular statements regarding species. This is because, oddly enough, evolutionary biolo gists are quite far from agreement on what a species is, how it attains this status, and what role it plays in evolution over the long term.

Species Problems and Beyond

Species Problems and Beyond PDF Author: John S. Wilkins
Publisher: CRC Press
ISBN: 1000549798
Category : Science
Languages : en
Pages : 383

Book Description
Species Problems and Beyond offers a collection of up-to-date essays discussing from an interdisciplinary perspective the many ramifications of the ‘Species Problem.’ The authors represent experts in the philosophy of biology, in species-level evolutionary investigations, and in biodiversity studies and conservation. Some of the topics addressed concern the context sensitivity of the term ‘species’; species as individuals, processes, natural kinds, or as ‘operative concepts’; species delimitation in the age of Big (genomic) Data; and taxonomic inflation and its consequences for conservation strategies. The carefully edited volume will be an invaluable resource for philosophers of biology and evolutionary biologists alike. – Olivier Rieppel, Rowe Family Curator of Evolutionary Biology, Negaunee Integrative Research Center, Field Museum, USA Species, or ‘the Species Problem’, is a topic in science, in the philosophy of science, and in general philosophy. In fact, it encompasses many aspects of the same problem, and these are dealt with in this volume. Species are often thought of as fundamental units of biological matter to be used in ecology, conservation, classification, and biodiversity. The chapters in this book present opposing views on the current philosophical and conceptual issues of the Species Problem in biology. Divided into four sections, Concepts and Theories, Practice and Methods, Ranks and Trees and Names, and Metaphysics and Epistemologies, the book is authored by biologists, philosophers, and historians, many leaders in their fields. Topics include ontology of species, definitions of both species category and units, species rank, speciation issues, nomenclature, ecology, and species conservation. Species Problems and Beyond aims to clarify the contemporary issues of the Species Problem. It is ideal for use in upper-level seminars and courses in Evolutionary Biology, Philosophy of Science, Philosophy of Biology, Systematics and Taxonomy, and Phylogenetics/Cladistics, and for any scholar in these fields.
