Download or read book Phylogeny and Evolution of the Mollusca written by Winston Ponder and published by Univ of California Press. This book was released on 2008-03-25 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Ponder and Lindberg provides a breathtaking overview of the evolutionary history of the Mollusca, effectively melding information from anatomy, ecology, genomics, and paleobiology to explore the depths of molluscan phylogeny. Its outstanding success is due to thoughtful planning, focused complementary contributions from 36 expert authors, and careful editing. This volume is a must for malacologists."—Bruce Runnegar, Department of Earth and Space Sciences, University of California, Los Angeles "Our understanding of the phylogeny and evolutionary history of the mollusca has been revolutionized over the past two decades through new molecular data and analysis, and reinvestigation of morphological characters. In this volume Ponder, Lindberg, and their colleagues do a wonderful job of integrating this work to provide new perspectives on the relationships of the major molluscan clades, their evolutionary dynamics, and their history. Particularly timely is the coverage of molluscan evo-devo and genomics."—Douglas H. Erwin, Curator of Paleozoic Invertebrates, National Museum of Natural History
Download or read book MorphoEvoDevo A Multilevel Approach to Elucidate the Evolution of Metazoan Organ Systems written by and published by Frontiers Media SA. This book was released on 2023-11-10 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analyzing animal development in a comparative framework provides a unique window into evolutionary history. With a long tradition that dates back to iconic 19th-century zoologists such as Ernst Haeckel and Charles Darwin, Evolutionary Developmental Biology is firmly rooted in morphological research. While studies using a classical model system approach have resulted in considerable methodological progress, in particular by establishing molecular genetic tools to tackle questions surrounding animal development, it quickly became obvious that a broad comparative dataset involving as many taxa as possible is necessary for sound evolutionary inferences. Thus, today’s EvoDevo embraces morphological, molecular, and experimental procedures, interpreted in a phylogenetic framework, in order to answer key questions that revolve around the evolution of animal cell types, organ systems, and, ultimately, entire species.
Download or read book Biological Systematics written by Alessandro Minelli and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: To some potential readers of this book the description of Biological System atics as an art may seem outdated and frankly wrong. For most people art is subjective and unconstrained by universal laws. While one picture, play or poem may be internally consistent comparison between different art products is meaningless except by way of the individual artists. On the other hand modern Biological Systematics - particularly phenetics and cladistics - is offered as objective and ultimately governed by universal laws. This implies that classifications of different groups of organisms, being the products of systematics, should be comparable irrespective of authorship. Throughout this book Minelli justifies his title by developing the theme that biological classifications are, in fact, very unequal in their expressions of the pattern and processes of the natural world. Specialists are imbibed with their own groups and tend to establish a consensus of what constitutes a species or a genus, or whether it should be desirable to recognize sub species, cultivars etc. Ornithologists freely recognize subspecies and rarely do bird genera contain more than 10 species. On the other hand some coleopterists and botanists work with genera with over 1500 species. This asymmetry may reflect a biological reality; it may express a working practicality, or simply an historical artefact (older erected genera often contain more species). Rarely are these phenomena questioned.
Download or read book Multicellular Animals written by Peter Ax and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: The system of multicellular animals presented here is an alternative to the traditional classification system. In a new approach to the phylogenetic order, this book strives for an objective systematization of the metazoa, seeking a new path in the field of academic research and teaching.

Available in PDF, EPUB and Kindle. Book excerpt: This study is organized around three themes: the origin and early diversification of life during the Archean Eon; the maturation of life and the Earth during the long Proterozoic Eon; and the explosive diversification of multicellular life that marks the dawn of the Phanerozoic Eon. The contributors discuss the coherence of history, the combinatorial generation of taxonomic diversity, early Metazoan evolution, and the Cambrian explosion.

Available in PDF, EPUB and Kindle. Book excerpt: Tackling one of the most difficult and delicate of the evolutionary questions, this challenging book summarizes the more recent results in phylogenetics and developmental biology that address the evolution of key innovations in metazoans. Divided into three sections, the first considers the phylogenetic issues involving this area of the tree of lif
Download or read book Photoreception and Vision in Invertebrates written by M. A. Ali and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 856 pages. Available in PDF, EPUB and Kindle. Book excerpt: I see a man's life is a tedious one. Cymbeline, Act III, Sc. 6. It is well known that the best way to learn a subject is to teach it! Along the same lines one might also say that a pleasant way of learning a subject and at the same time getting to know quite a few of the workers active in it, is to arrange and to attend an Advanced Study Institute (ASI) or a workshop lasting about two weeks. This was and is the wisdom behind the NA TO-ASI programme and much as people fear that a fortnight may be too long, before it is over everyone feels that it was too short, especially if the weather had cooperated. Organising this ASI which resulted in this volume has been a very good learning experience. I started my career in research with invertebrates and retained an interest in them over the years due to my teaching a course and working sporadically on various aspects of photoreception in Polychaetes, Crustaceans and Insects. Thus, the thought of organising an ASI on photoreception and vision in invertebrates had been brewing in my mind for the past half a dozen years or so. It was felt that it will be desirable to do a bit of stock taking and discuss possible new approaches to the study of this matter.
Download or read book The Phylogenetic System written by Peter Ax and published by . This book was released on 1987-09-24 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: This excellent translation of the German Das Phylogenetische System explains, simply and logically, the functions of the phylogenetic system how it must be built up. Written by one of Germany's most distinguished systematic zoologists, the text clarifies several basic concepts, such as monophyly, the stem lineage, autapomorphy, and synapomorphy. The presentation is illustrated mainly by examples drawn from arthropods and vertebrates and will thus be widely intelligable to students of biology.
Download or read book A Theory of Human and Primate Evolution written by Colin P. Groves and published by . This book was released on 1991 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the evidence of primate and human evolution in the light of new evolutionary models and advances in taxonomic theory. Dr. Groves discusses the "Nomogenesis" of Lev Berg and criticizes the cladistic school of taxonomy, adapting it in the light of theories of speciation. The result is a theory in which internal processes play a major role in human evolution and taxonomy becomes of major importance in evolutionary interpretation. The book will interest students and teachers of human biology and evolution, physical anthropologists, zoologists, paleontologists, and primatologists.
