Book excerpt: A readily comprehensible guide for biologists, field taxonomists and interested laymen to one of the oldest problems in biology: the species problem. Written by a geneticist with extensive experience in field taxonomy, this practical book provides the sound scientific background to the problems arising with classifying organisms according to species. It covers the main current theories of specification and gives a number of examples that cannot be explained by any single theory alone.
Download or read book Species Concepts in Biology written by Frank E. Zachos and published by Springer. This book was released on 2016-10-05 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Frank E. Zachos offers a comprehensive review of one of today’s most important and contentious issues in biology: the species problem. After setting the stage with key background information on the topic, the book provides a brief history of species concepts from antiquity to the Modern Synthesis, followed by a discussion of the ontological status of species with a focus on the individuality thesis and potential means of reconciling it with other philosophical approaches. More than 30 different species concepts found in the literature are presented in an annotated list, and the most important ones, including the Biological, Genetic, Evolutionary and different versions of the Phylogenetic Species Concept, are discussed in more detail. Specific questions addressed include the problem of asexual and prokaryotic species, intraspecific categories like subspecies and Evolutionarily Significant Units, and a potential solution to the species problem based on a hierarchical approach that distinguishes between ontological and operational species concepts. A full chapter is dedicated to the challenge of delimiting species by means of a discrete taxonomy in a continuous world of inherently fuzzy boundaries. Further, the book outlines the practical ramifications for ecology and evolutionary biology of how we define the species category, highlighting the danger of an apples and oranges problem if what we subsume under the same name (“species”) is in actuality a variety of different entities. A succinct summary chapter, glossary and annotated list of references round out the coverage, making the book essential reading for all biologists looking for an accessible introduction to the historical, philosophical and practical dimensions of the species problem.

Download or read book The Pangenome written by Hervé Tettelin and published by Springer Nature. This book was released on 2020-04-30 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book offers the first comprehensive account of the pan-genome concept and its manifold implications. The realization that the genetic repertoire of a biological species always encompasses more than the genome of each individual is one of the earliest examples of big data in biology that opened biology to the unbounded. The study of genetic variation observed within a species challenges existing views and has profound consequences for our understanding of the fundamental mechanisms underpinning bacterial biology and evolution. The underlying rationale extends well beyond the initial prokaryotic focus to all kingdoms of life and evolves into similar concepts for metagenomes, phenomes and epigenomes. The book’s respective chapters address a range of topics, from the serendipitous emergence of the pan-genome concept and its impacts on the fields of microbiology, vaccinology and antimicrobial resistance, to the study of microbial communities, bioinformatic applications and mathematical models that tie in with complex systems and economic theory. Given its scope, the book will appeal to a broad readership interested in population dynamics, evolutionary biology and genomics.
Download or read book Metaphysics and the Origin of Species written by Michael T. Ghiselin and published by SUNY Press. This book was released on 1997-01-01 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book The Species Problem written by Richard A. Richards and published by Cambridge University Press. This book was released on 2010-07-01 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Survival of the Friendliest written by Brian Hare and published by Random House. This book was released on 2020-07-14 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: A powerful new theory of human nature suggests that our secret to success as a species is our unique friendliness “Brilliant, eye-opening, and absolutely inspiring—and a riveting read. Hare and Woods have written the perfect book for our time.”—Cass R. Sunstein, author of How Change Happens and co-author of Nudge For most of the approximately 300,000 years that Homo sapiens have existed, we have shared the planet with at least four other types of humans. All of these were smart, strong, and inventive. But around 50,000 years ago, Homo sapiens made a cognitive leap that gave us an edge over other species. What happened? Since Charles Darwin wrote about “evolutionary fitness,” the idea of fitness has been confused with physical strength, tactical brilliance, and aggression. In fact, what made us evolutionarily fit was a remarkable kind of friendliness, a virtuosic ability to coordinate and communicate with others that allowed us to achieve all the cultural and technical marvels in human history. Advancing what they call the “self-domestication theory,” Brian Hare, professor in the department of evolutionary anthropology and the Center for Cognitive Neuroscience at Duke University and his wife, Vanessa Woods, a research scientist and award-winning journalist, shed light on the mysterious leap in human cognition that allowed Homo sapiens to thrive. But this gift for friendliness came at a cost. Just as a mother bear is most dangerous around her cubs, we are at our most dangerous when someone we love is threatened by an “outsider.” The threatening outsider is demoted to sub-human, fair game for our worst instincts. Hare’s groundbreaking research, developed in close coordination with Richard Wrangham and Michael Tomasello, giants in the field of cognitive evolution, reveals that the same traits that make us the most tolerant species on the planet also make us the cruelest. Survival of the Friendliest offers us a new way to look at our cultural as well as cognitive evolution and sends a clear message: In order to survive and even to flourish, we need to expand our definition of who belongs.

Download or read book Systematics and the Origin of Species written by National Academy of Sciences and published by National Academies Press. This book was released on 2005-09-28 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: In December 2004, the National Academy of Sciences sponsored a colloquium on "Systematics and the Origin of Species" to celebrate Ernst Mayr's 100th anniversary and to explore current knowledge concerning the origin of species. In 1942, Ernst Mayr, one of the twentieth century's greatest scientists, published Systematics and the Origin of Species, a seminal book of the modern theory of evolution, where he advanced the significance of population variation in the understanding of evolutionary process and the origin of new species. Mayr formulated the transition from Linnaeus's static species concept to the dynamic species concept of the modern theory of evolution and emphasized the species as a community of populations, the role of reproductive isolation, and the ecological interactions between species. In addition to a preceding essay by Edward O. Wilson, this book includes the 16 papers presented by distinguished evolutionists at the colloquium. The papers are organized into sections covering the origins of species barriers, the processes of species divergence, the nature of species, the meaning of "species," and genomic approaches for understanding diversity and speciation.

Download or read book Two Human Species Exist written by Bruce Eldine Morton and published by . This book was released on 2012-03 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two human species have long existed, unrecognized in front of our very eyes. They are Homo sapiens patripolaris and Homo sapiens matripolaris. Their reproductive differences remain unnoticed. Yet, because they are two different species, when they cross-breed, their hybrid offspring are cross-wired to produce Dyslexics, Homosexuals, Pedophiles, and Schizophrenics. This book contains published questionnaires that enable you to find your hemisity, your familial polarity, learn to which species you belong, and what type of "normal" or hybrid you are. Unrecognized, life-affecting differences in courtship and child rearing exist between the two species. This is the topic of Familial Polarity whose ancient existence and influence upon history you can confirm for yourself. Ignorance of familial polarity is a major source of multiple levels of global conflict.
