Download or read book On the Origin of Phyla written by James W. Valentine and published by University of Chicago Press. This book was released on 2004-06-18 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: Owing its inspiration and title to On the Origin of Species, James W. Valentine's ambitious book synthesizes and applies the vast treasury of theory and research collected in the century and a half since Darwin's time. By investigating the origins of life's diversity, Valentine unlocks the mystery of the origin of phyla. One of the twentieth century's most distinguished paleobiologists, Valentine here integrates data from molecular genetics, evolutionary developmental biology, embryology, comparative morphology, and paleontology into an analysis of interest to scholars from any of these fields. He begins by examining the sorts of evidence that can be gleaned from fossils, molecules, and morphology, then reviews and compares the basic morphology and development of animal phyla, emphasizing the important design elements found in the bodyplans of both living and extinct phyla. Finally, Valentine undertakes the monumental task of developing models to explain the origin and early diversification of animal phyla, as well as their later evolutionary patterns. Truly a magnum opus, On the Origin of Phyla will take its place as one of the classic scientific texts of the twentieth century, affecting the work of paleontologists, morphologists, and developmental, molecular, and evolutionary biologists for decades to come. "A magisterial compendium . . . . Valentine offers a judicious evaluation of an astonishing array of evidence."—Richard Fortey, New Scientist "Truly a magnum opus, On the Origin of Phyla has already taken its place as one of the classic scientific texts of the twentieth century, affecting the work of paleontologists, morphologists, and developmental, molecular, and evolutionary biologists for decades to come."—Ethology, Ecology & Evolution "Valentine is one of the Renaissance minds of our time. . . . Darwin wisely called his best-known work On the Origin of the Species; the origin of the phyla is an even stickier problem, and Valentine deserves credit for tackling it at such breadth . . . . A magnificient book."—Stefan Bengtson, Nature

Download or read book A Manual of Zoology written by Richard Hertwig and published by . This book was released on 1912 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Manual of Zoology The favor with which the first and second American editions of Hertwig's Zoology have been received has led to a thorough revision of the whole with a close comparison with the latest German edition. In this there have been introduced many new features bringing the work up to date. These include a discussion of Mendelian inheritance, many modifications in the account of the theory of evolution, and a considerable enlargement of the Protozoa and especially of the pathogenic forms, making the volume of more value to the student of medicine. To have included these without changes elsewhere would have resulted in a much larger volume. But the demand in American colleges has been for a smaller work and so a reduction has been made in two ways. There has been a condensation by the elimination of unnecessary words and phrases and by the omission of considerable matter of minor importance. Then there has been the recognition of the fact that the book has two uses, one in the class room the other as a reference work. The two classes of matter have been distinguished by difference of type. No attempt has been made to bring the systematic names into accord with the latest vagaries of the systematists. No useful and could be served by changing or transferring the well-known names of Echidna, Coluber, Amia, Homarus, Unio, Holothuria, Am ba, etc., while the confusion this would introduce would be enormous. It should be understood that while the revision is based upon the German edition of Professor Hertwig, he should not be held responsible for any changes introduced. The whole responsibility for these rests upon the American reviser.

Download or read book Coelenterate Ecology and Behavior written by G.O. Mackie and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 723 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of coelenterates is now one of the most active fields of invertebrate zoology. There are many reasons for this, and not everyone would agree on them, but certain facts stand out fairly clearly. One of them is that many of the people who study coelenterates do so simply because they are interested in the animals for their own sake. This, however, would be true for other invertebrate groups and cannot by itself explain the current boom in coelenterate work. The main reasons for all this activity seem to lie in the considerable concentration of research effort and funding into three broad, general areas of biology: marine ecology, cellular-developmental biology and neurobiology, in all of which coelenterates have a key role to play. They are the dominant organisms, or are involved in an important way, in a variety of marine habitats, of which coral reefs are only one, and this automatically ensures their claims on the attention of ecologists and marine scientists. Secondly, the convenience of hydra and some other hydroids as experimental animals has long made them a natural choice for a variety of studies on growth, nutrition, symbiosis, morphogenesis and sundry aspects of cell biology. Finally, the phylogenetic position of the coelenterates as the lowest metazoans having a nervous system makes them uniquely interesting to those neurobiologists and behaviorists who hope to gain insights into the functioning of higher nervous systems by working up from the lowest level.

Download or read book Coelenterate Biology written by Leonard Muscatine and published by Elsevier. This book was released on 2012-12-02 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coelenterate Biology: Reviews and New Perspectives highlights research areas in which coelenterates are exceptionally useful and interesting experimental animals. It outlines the state of knowledge in coelenterate research and draws attention to some of the challenging problems that are amenable for study. Coelenterates offer valuable material for many levels of inquiry—from the population and organismic to the cellular, subcellular, and molecular levels. They are especially attractive animals for studies in developmental biology and behavior. The book begins by discussing cnidarians histology, focusing on the light and electron microscopy of cnidarian tissues. There are separate chapters on the skeletal system of cnidarians; the morphology, functions, and chemistry of nematocytes; and a few aspects of the enormous subject of cnidarian development. The subsequent chapters deal with cnidarian neurobiology, behavior, locomotion, flotation, and dispersal; experimental studies on algae-cnidarian symbioses; and coelenterate bioluminescence. The book concludes with a discussion of the systems of coordination and nervous system of ctenophores.
