Download or read book Molecular Evolution: Evidence for Monophyly 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 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.

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.

Book excerpt: Zoology, Volume 16: The Evolution of the Metozoa presents the significant results of the Cnidaria research, their interpretations and implications in the field of zoology. This book is composed of four chapters, and begins with the establishment of the systematic position of the Spongiae, the position of Ctenophora in the animal classification, and Cnidaria as the only Coelenterata. The subsequent chapter deals with a critical survey of the interpretations of the origin and nature of Cnidaria, with emphasis on the morphologic proofs of its phylogeny. These topics are followed by an outline of the most probable reconstruction of the phylogeny of Cnidaria and the descriptions of the evolution of this metozoa. The final chapter considers the established classification of the animal world and the genealogical tree. This book will be of value to zoologists and researchers who are interested in evolution and classification of Cnidaria.

Book excerpt: Perspectives in Zoology tries to discuss in a critical way some of the aspects of biology that lack perspective. The book also calls into attention the possibilities of obtaining a more correct view and challenges views that already have already been accepted by the scientific community. In this thought-provoking book, many questions are raised and different viewpoints and their implications are considered in the areas of natural history. Coverage includes the great ages of evolution; the primitive evolution in the eumatozoa; the morphological comparisons between homology and analogy; systematic serology and its principles; and the relationship of systemics, evolution, and phylogeny. The text is recommended for students and professors that deal with biology, zoology, genetics, and evolution who not only wish to explore and understand other approaches to popular theories in zoology, but also wish to be more familiarized and delve deeper with the common yet frequently discussed and debated topics in the field.

This book was released on 2014-02-27 with total page 764 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growing success of molecular methods has challenged traditional views of animal evolution and a large number of alternative hypotheses are hotly debated today. For the deep metazoan phylogeny project, data sets of hitherto unmatched quality and quantity were compiled and analysed with innovative bioinformatics tools. The book begins at the base of the tree of life to discuss the origin of animals and early branches of the phylogenetic tree. The following section presents special data sets gained from mitochondrial genomes and from morphology, with a focus on nervous systems. The final section is dedicated to theoretical aspects of data analysis and new bioinformatics tools. The book closes with a unique general discussion of all hypotheses contained in previous chapters. This work provides the most comprehensive overview available of the state of the art in this exciting field of evolutionary research.

This book was released on 2006-03-30 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, evidence has been accumulated which shows that some of the groups formerly regarded as independent "phyla" such as Pogonophora (now recognized as Siboglinidae), Echiura, Myzostomida and perhaps Sipuncula, are most probably nothing else than greatly modified Annelida. The extreme morphological diversity found especially in Polychaeta displays the plasticity of a simple segmented organisation that basically is nothing else but a serial repetition of identical units. Thus, annelids are highly important to our understanding of fundamental questions about morphological and adaptive diversity, as well as clarifying evolutionary changes and phylogenetic relationships. The book aims to summarize our knowledge on Polychaetes polychaetes and their allies and gives an overview of recent advances gained by studies that employed conventional and modern methods plus, increasingly and importantly, the use of molecular markers and computer-assisted kinship analyses. It also reflects the state of art in polychaete sciences and presents new questions and controversies. As such it will significantly influence the direction of research on Polychaeta and their related taxa.

Available in PDF, EPUB and Kindle. Book excerpt: Reproduction of Marine Invertebrates, Volume I: Acoelomate and Pseudocoelomate Metazoans is a collection of papers that deals with the evolution of reproductive mechanisms and behavior in marine invertebrates. This collection starts with terminologies and basic events in marine invertebrate reproduction, including the method of estimating sexual reproductive activity, as well as the timing and patterns involved. The book notes that temperatures, salinities, or food availability should be favorable when the young are produced and when they are developing. One paper shows that the reproductive rhythm is dynamic and in some species is latitude-dependent. Other papers discuss the reproductive cycles of different marine invertebrates such as the Porifera, Cnidaria, Nemertinea, and Nematoda. These papers include topics on asexual reproduction, regeneration, sexual reproduction, and development, and then explain in detail the development of certain invertebrates from their kinorhynchs state (embryonic), to the molting stages, juvenile stages, then to adulthood. This book can be useful for marine biologists, marine ecologists, and students involved in marine biological and physical sciences.

Download or read book Human Ecology and Infectious Diseases written by Neil A. Croll and published by Academic Press. This book was released on 2013-09-03 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human Ecology and Infectious Diseases investigates the interrelationships among human behavior, ecology, and infectious diseases, with emphasis on parasitic and zoonotic diseases. The cultural, behavioral, anthropological, and social factors in the transmission of infectious diseases are discussed, along with methods used to make human ecology a more quantitative predictive science in the global challenge of such diseases. Behavioral patterns that place humans at risk to infections and the nature of risk factors are also analyzed. Comprised of 13 chapters, this book begins with an overview of some of the research into those aspects of human behavior that determine risk of helminth infection. The discussion then turns to studies on hookworm and includes an analysis of human behavior and religions that affect transmission of the parasitoses. Human behavior and transmission of zoonotic diseases in North America and Malaysia are documented as are the habits, customs, and superstitions associated with the epidemic of intestinal capillariasis that occurred in the Philippines. Filarial diseases in Southeast Asia are also reviewed, along with the changing patterns of parasitic infections and the cooperation of government and the private sector to lower infection rates in Japan. Cases from Nigeria and Brazil are considered as well. The volume concludes with an assessment of the importance of behavioral and socialcultural factors in determining regional and national patterns in disease incidence and transmission. This monograph should be valuable to students of tropical diseases and public health and to physicians, epidemiologists, anthropologists, veterinarians, and parasitologists.

Download or read book The Comparative Embryology of Sponges written by Alexander V. Ereskovsky and published by Springer Science & Business Media. This book was released on 2010-03-27 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the major questions in the evolution of animals is the transition from unicellular to multicellular organization, which resulted in the emergence of Metazoa through a hypothetical Urmetazoa. The Comparative Embryology of Sponges contains abundant original and literary data on comparative embryology and morphology of the Porifera (Sponges), a group of 'lower Metazoa'. On the basis of this material, original typization of the development of Sponges is given and the problems concerning origin and evolution of Porifera and their ontogenesis are discussed. A morphogenetic interpretation of the body plan development during embryogenesis, metamorphosis and asexual reproduction in Sponges is proposed. Special attention is given to the analysis of characteristic features of the ontogenesis in Porifera. The book pursues three primary goals: 1) generalization of all existing information on individual development of sponges, its classification and a statement according to taxonomical structure of Porifera; 2) revealing of heterogeneity of morphogenesis and peculiarities of ontogeneses in various clades of Porifera, and also their correlations with the organization, both adult sponges, and their larvae; 3) revealing homology of morphogeneses in both Porifera and Eumetazoa, testifying to the general evolutionary roots of multicellular animals, and peculiar features of sponges' morphogeneses and ontogenesis. This book will be of interest to embryologists, zoologists, morphologists and researchers in evolutionary biology.
