Download or read book Animal Evolution Interrelationships of the Living Phyla written by Claus Nielsen and published by OUP Oxford. This book was released on 2001-03-08 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal Evolution is a complete analysis of the evolutionary interrelationships and myriad diversity of the animal kingdom. Using modern phylogenetic reasoning based on characters from an extensive review of morphology, including ultrastructure, and embryology, each phylum is analysed to ascertain its monophyly and hence its ancestral characters. These ancestral characters are then used to construct a complete phylogenetic tree of the extant animal phyla. This new edition of Animal Evolution brings the subject fully up to date including some new ideas and emphases, as well as new bibliographic data. It also includes new chapters on the use of computer programmes and on the use of the new molecular techniques to create phylogenies, both techniques that have grown in prevalence in the field since the first edition was published. Illustrated throughout with finely detailed line drawings and clear diagrams. From reviews of the first edition of Animal Evolution: 'A clear and engaging style exemplified by a series of superbly concise descriptions of the phyla.... These are complemented by excellent illustrations.... The volume belongs on every biologist's bookshelf.' Simon Conway- Morris, Nature 'Texts like these constitute the very cream of taxonomic literature.... It really is a joy to read... and in my opinion it constitutes a highly recommended book for all zoologists. I think it is also particularly suited for seminars on animal classification for both undergraduate and graduate students.' JC von Vaupel Klein, Crustaceana 'I highly recommend this book as a fascinating theory of animal relationships, and an excellent summary of the phylogenetically informative aspects of the biology of the whole animal kingdom.' Maximilian J Telford, Systematic Entomology
Download or read book Old Questions and Young Approaches to Animal Evolution written by José M. Martín-Durán and published by Springer. This book was released on 2019-07-22 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal evolution has always been at the core of Biology, but even today many fundamental questions remain open. The field of animal ‘evo-devo’ is leveraging recent technical and conceptual advances in development, paleontology, genomics and transcriptomics to propose radically different answers to traditional evolutionary controversies. This book is divided into four parts, each of which approaches animal evolution from a different perspective. The first part (chapters 2 and 3) investigates how new sources of evidence have changed conventional views of animal origins, while the second (chapters 4–8) addresses the connection between embryogenesis and evolution, and the genesis of cellular, tissue and morphological diversity. The third part (chapters 9 and 10) investigates how big data in molecular biology is transforming our understanding of the mechanisms governing morphological change in animals. In closing, the fourth part (chapters 11–13) explores new theoretical and conceptual approaches to animal evolution. ‘Old questions and young approaches to animal evolution’ offers a comprehensive and updated view of animal evolutionary biology that will serve both as a first step into this fascinating field for students and university educators, and as a review of complementary approaches for researchers.
Download or read book Arthropod Biology and Evolution written by Alessandro Minelli and published by Springer Science & Business Media. This book was released on 2013-04-11 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than two thirds of all living organisms described to date belong to the phylum Arthropoda. But their diversity, as measured in terms of species number, is also accompanied by an amazing disparity in terms of body form, developmental processes, and adaptations to every inhabitable place on Earth, from the deepest marine abysses to the earth surface and the air. The Arthropoda also include one of the most fashionable and extensively studied of all model organisms, the fruit-fly, whose name is not only linked forever to Mendelian and population genetics, but has more recently come back to centre stage as one of the most important and more extensively investigated models in developmental genetics. This approach has completely changed our appreciation of some of the most characteristic traits of arthropods as are the origin and evolution of segments, their regional and individual specialization, and the origin and evolution of the appendages. At approximately the same time as developmental genetics was eventually turning into the major agent in the birth of evolutionary developmental biology (evo-devo), molecular phylogenetics was challenging the traditional views on arthropod phylogeny, including the relationships among the four major groups: insects, crustaceans, myriapods, and chelicerates. In the meantime, palaeontology was revealing an amazing number of extinct forms that on the one side have contributed to a radical revisitation of arthropod phylogeny, but on the other have provided evidence of a previously unexpected disparity of arthropod and arthropod-like forms that often challenge a clear-cut delimitation of the phylum.
