Book Synopsis Molecular Evolution: Towards the Origin of Metazoa by : Werner E.G. Müller
Download or read book Molecular Evolution: Towards the Origin of Metazoa written by Werner E.G. Müller and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, new genes and their proteins that revealed striking new insights into the early evolution of multicellular animals have been identified and characterized from members of the lowest metazoan phylum, the porifera (sponges). The unexpected result was that the sequences obtained from sponge displayed high similarity to those found in higher metazoa; in consequence, it was concluded that during the transition from protozoa to metazoa the major structural and regulatory proteins evolved only once. The data gathered are now powerful arguments to establish monophyly of metazoa; in addition, new insights on the evolutionary diversification of metazoa were obtained.

This book was released on 2012-12-06 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume concentrates on the origin of multicellular animals, Metazoa. Until now, no unequivocal phylogeny has been produced. Therefore, the questions remain: Did Metazoa evolve from the Protozoa only once, or several times? Is the origin of animals monophyletic or polyphyletic? Especially the relationships between the existing lower metazoan phyla, particularly the Porifera (sponges) are uncertain. Based on sequence data of genes typical for multicellularity it is demonstrated that all Metazoa, including Porifera, should be placed into the kingdom Animalia together with the Eumetazoa. Therefore it is most likely that all animals are of monophyletic origin.
Book Synopsis Molds, Molecules, and Metazoa by : Peter R. Grant
Download or read book Molds, Molecules, and Metazoa written by Peter R. Grant and published by Princeton University Press. This book was released on 2014-07-14 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Through an integration of systematics, genetics, and related disciplines, the Modern Synthesis of Evolutionary Biology came into being over fifty years ago. Knowledge of evolution has since been transformed by several revolutions: the way we interpret the fossil record has been radically affected by theories of continental drift and asteroid impacts; the way we classify organisms has been influenced by the development of cladistics. Perhaps the most dramatic revolution has been the explosion in molecular biology of information about the genome. Aiming to capture the excitement of modern evolutionary biology, six prominent scientists here explore important issues and problems in their areas of specialization and identify the most promising directions of future research. The scope of this volume ranges from macroevolutionary patterns in the Precambrian to molecular evolution of the genome. Major themes include the origin and maintenance of variation and the causes of evolutionary change. Chapters on paleontology, ecology, behavior, development, and cell and molecular biology are contributed by Jim Valentine, Graham Bell, Mary Jane West Eberhard, Leo Buss, Marc Kirschner, and Marty Kreitman. The book contains an introductory chapter by John Bonner, whose seminal work is honored here. Originally published in 1992. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
Book Synopsis Origin and Evolution of Metazoan Cell Types by : Sally Leys
Download or read book Origin and Evolution of Metazoan Cell Types written by Sally Leys and published by CRC Press. This book was released on 2021-05-23 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolution of animal diversity is strongly affected by the origin of novel cell and tissue types and their interactions with each other. Understanding the evolution of cell types will shed light on the evolution of novel structures, and in turn highlight how animals diversified. Several cell types may also have been lost as animals simplified – for example did sponges have nerves and lose them? This book reveals the interplay between gains and losses and provides readers with a better grasp of the evolutionary history of cell types. In addition, the book illustrates how new cell types allow a better understanding permitting the discrimination between convergence and homology.

Book Synopsis Molecular Markers, Natural History and Evolution by : J. C. Avise
Download or read book Molecular Markers, Natural History and Evolution written by J. C. Avise and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular approaches have opened new windows on a host of ecological and evolutionary disciplines, ranging from population genetics and behavioral ecology to conservation biology and systematics. Molecular Markers, Natural History and Evolution summarizes the multi-faceted discoveries about organisms in nature that have stemmed from analyses of genetic markers provided by polymorphic proteins and DNAs. The first part of the book introduces rationales for the use of molecular markers, provides a history of molecular phylogenetics, and describes a wide variety of laboratory methods and interpretative tools in the field. The second and major portion of the book provides a cornucopia of biological applications for molecular markers, organized along a scale from micro-evolutionary topics (such as forensics, parentage, kinship, population structure, and intra-specific phylogeny) to macro-evolutionary themes (including species relationships and the deeper phylogenetic structure in the tree of life). Unlike most prior books in molecular evolution, the focus is on organismal natural history and evolution, with the macromolecules being the means rather than the ends of scientific inquiry. Written as an intellectual stimulus for the advanced undergraduate, graduate student, or the practicing biologist desiring a wellspring of research ideas at the interface of molecular and organismal biology, this book presents material in a manner that is both technically straightforward, yet rich with concepts and with empirical examples from the world of nature.

Book Synopsis Encyclopedia of Geobiology by : Joachim Reitner
Download or read book Encyclopedia of Geobiology written by Joachim Reitner and published by Springer. This book was released on 2011-03-10 with total page 927 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interplay between Geology and Biology has shaped the Earth from the early Precambrian, 4 billion years ago. Moving beyond the borders of the classical core disciplines, Geobiology strives to identify chains of cause-and-effect and synergisms between the geo- and the biospheres that have been driving the evolution of life in modern and ancient environments. Combining modern methods, geobiological information can be extracted not only from visible remains of organisms, but also from organic molecules, rock fabrics, minerals, isotopes and other tracers. An understanding of these processes and their signatures reveals enormous applied potentials with respect to issues of environment protection, public health, energy and resource management. The Encyclopedia of Geobiology has been designed to act as a key reference for students, researchers, teachers, and the informed public and to provide basic, but comprehensible knowledge on this rapidly expanding discipline that sits at the interface between modern geo- and biosciences.

Book Synopsis The Causes of Molecular Evolution by : John H. Gillespie
Download or read book The Causes of Molecular Evolution written by John H. Gillespie and published by Oxford University Press. This book was released on 1994-05-26 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work provides a unified theory that addresses the important problem of the origin and maintenance of genetic variation in natural populations. With modern molecular techniques, variation is found in all species, sometimes at astonishingly high levels. Yet, despite these observations, the forces that maintain variation within and between species have been difficult subjects of study. Because they act very weakly and operate over vast time scales, scientists must rely on indirect inferences and speculative mathematical models. However, despite these obstacles, many advances have been made. The author's research in molecular genetics, evolution, and bio-mathematics has enabled him to draw on this work, and present a coherent and valuable view of the field. The book is divided into three parts. The first consists of three chapters on protein evolution, DNA evolution, and molecular mechanisms. This section reviews the experimental observations on genetic variation. The second part gives a unified treatment of the mathematical theory of selection in a fluctuating environment. The final two chapters combine the earlier assessments in a treatment of the scientific status of two competing theories for the maintenance of genetic variation. Steeped in the enormous advances population genetics has made over the past 25 years, this book has proven highly popular among human geneticists, biologists, evolutionary theorists, and bio-mathematicians.
Download or read book Thermophiles written by Juergen Wiegel and published by CRC Press. This book was released on 2002-09-11 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: Late-1990s developments in the study of thermophiles have had considerable significance on theories of evolution. These micro-organisms are able to thrive at temperatures near or even above 100 degrees Celsius, and scientists have begun to study their biology in an attempt to provide clues about the beginnings of life on our planet. Researchers from diverse background such as biology, genetics, biogeochemistry, oceanography, systematics and evolution come together in this comprehensive volume to address questions such as: Why did life originate? Was the Earth at high temperatures when life began, and if so, how high? What can we conclude about the origins of life from studying thermophilic organisms?

Download or read book Evolution of Life written by Syozo Osawa and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly thirty million species of organisms are believed to now live on Earth. In addition to accumulating evidence from classical biology, paleontology and earth science, the recent progress of molecular biology has provided new insights into understanding how present-day organisms have evolved with such tremendous diversity. Molecular biological studies show us that all living forms, including E. coli and human beings, derive from a single ancestor that emerged some 4 billion years ago on Earth. This volume aims to discuss the motifs of organismic evolution from the viewpoints of biogeo-interactions and diversification of the genetic systems. Based on these fundamental understandings, the last section of this volume is devoted to human evolution that includes phylogeny of man as well as evolution of human culture. Such comprehensive discussion will give us a synthesized view of the evolution of life, that is undoubtedly one of the most important problems not only for science but also for human culture in general.
