Available in PDF, EPUB and Kindle. Book excerpt: “Addresses an important topic for biologists and zoologists about vertebrates’ place in the ‘grand scheme’ . . . genuinely witty and charming . . . magnificent.” —Neil J. Gostling, University of Southampton Our understanding of vertebrate origins and the backbone of human history evolves with each new fossil find and DNA map. Many species have now had their genomes sequenced, and molecular techniques allow genetic inspection of even non-model organisms. But as longtime Nature editor Henry Gee argues in Across the Bridge, despite these giant strides and our deepening understanding of how vertebrates fit into the tree of life, the morphological chasm between vertebrates and invertebrates remains vast and enigmatic. As Gee shows, even as scientific advances have falsified a variety of theories linking these groups, the extant relatives of vertebrates are too few for effective genetic analysis. Moreover, the more we learn about the species that do remain—from sea-squirts to starfish—the clearer it becomes that they are too far evolved along their own courses to be of much use in reconstructing what the latest invertebrate ancestors of vertebrates looked like. Fossils present yet further problems of interpretation. Tracing both the fast-changing science that has helped illuminate the intricacies of vertebrate evolution as well as the limits of that science, Across the Bridge helps us to see how far the field has come in crossing the invertebrate-to-vertebrate divide—and how far we still have to go. “A beautiful ode to some of the least appreciated animals . . . guides the reader joyfully through deuterostomes—weaving disparate elements of embryology, paleontology, and morphology into an unprecedented and accessible narrative.” —Jakob Vinther, University of Bristol

Available in PDF, EPUB and Kindle. Book excerpt: Atlas of Comparative Vertebrate Histology looks at the histology of a wide range of vertebrates, representative of all the major classes and families, with examples ranging from amphioxus to primates. The authors focus their microscope on commonly seen vertebrates as well as 'non-standard' species, such as lamprey, hagfish, dogfish, skate, rock bass, cod, river catfish, toad, amphiuma, leopard and bull frog, garter and brown snake, Coturnix quail and cowbird. The study of comparative histology in the vertebrates helps students and researchers alike understand how various groups have addressed similar problems, opening doors to interesting research possibilities. Not all vertebrates follow the mammalian model of tissue and organ structure. When dealing with unique species, we see some structures taken beyond their 'normal' function. Comparative histology allows us to understand the structural responses underlying the physiology unique to each vertebrate group. - Presents the histology of a wide range of vertebrates, representative of all the major classes and families, with examples ranging from amphioxus to primates - Includes an image gallery with over 500 flat images and 50+ virtual microscopy slides - Contains electronic content features cross linking between text, tables and the image gallery

Download or read book Towards a New Neuromorphology written by Rudolf Nieuwenhuys and published by Springer. This book was released on 2015-12-28 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book demonstrates that the systematic study of gene expression patterns in embryonic and adult brains, in combination with selected data from earlier studies, can pave the way for a new neuromorphology, the most salient features of which may be summarized as follows: (1) Causal analysis of molecular patterning at neural plate and early neural tube stages has shown that the CNS is essentially organized into transverse neural segments or neuromeres and longitudinal zones which follow the curved axis of the brain. (2) The FMUs initially represent thin neuroepithelial fields; in the course of further development they are transformed into three-dimensional radial units, extending from the ventricular surface to the meningeal surface of the brain. (3) The principal histogenetic processes, including cellular proliferation, cell migration and differentiation, essentially take place within the confines of these radial units, controlled by characteristic sets of developmental regulatory genes. (4) Although most developing neurons migrate radially and settle within their own FMU, at many locations neuroblasts leave the FMU where they were produced and migrate tangentially to other nearby or remote territories, colonizing parts of foreign FMUs. (5) Many structural complexes in the adult brain, including the cerebral and cerebellar cortices, are the products of radial and tangential intermingling of migrated cell contingents. (6) By using appropriate molecular markers, all neuron types in the adult CNS can be traced back to a specific progenitor zone within a specific FMU, and the progeny of any FMU can be traced to their final positions with the help of selective labeling approaches. (7) Early outgrowing axons form bundles, which tend to pass close to the border zones of the radial units. By means of their molecularly diversely tuned growth cones, these extending axons decide how to behave at each boundary they encounter, sometimes even reorienting at right angles. Collectively these early axonal bundles form a checkerboard-like scaffold, which accentuates the molecular regionalization of the CNS and leads to the formation of topographically ordered synaptic fields. The book covers all of these aspects in detail, providing a morphologic model (blueprint) that highlights the natural coordinates of CNS structure resulting from the conserved molecularly controlled shaping phenomena within morphogenetic fields.

Download or read book Vertebrate Cranial Placodes written by GERHARD. SCHLOSSER and published by CRC Press. This book was released on 2021-04-29 with total page 752 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the cranial sense organs of vertebrates arise from embryonic structures known as cranial placodes. Such placodes also give rise to sensory neurons that transmit information to the brain as well as to many neurosecretory cells. This book focuses on the development of sensory and neurosecretory cell types from cranial placodes by introducing the vertebrate head with its sense organs and neurosecretory organs and providing an overview of the various cranial placodes and their derivatives, including evidence of common embryonic primordia. Schlosser discusses how these primordia are established in the early embryo and how individual placodes develop. The latter chapters explain how various placodally derived sensory and neurosecretory cell types differentiate into discrete structures.

Download or read book Chordate Origins and Evolution written by Noriyuki Satoh and published by Academic Press. This book was released on 2016-07-14 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chordate Origins and Evolution: The Molecular Evolutionary Road to Vertebrates focuses on echinoderms (starfish, sea urchins, and others), hemichordates (acorn worms, etc.), cephalochordates (lancelets), urochordates or tunicates (ascidians, larvaceans and others), and vertebrates. In general, evolution of these groups is discussed independently, on a larger scale: ambulacrarians (echi+hemi) and chordates (cephlo+uro+vert). Until now, discussion of these topics has been somewhat fragmented, and this work provides a unified presentation of the essential information. In the more than 150 years since Charles Darwin proposed the concept of the origin of species by means of natural selection, which has profoundly affected all fields of biology and medicine, the evolution of animals (metazoans) has been studied, discussed, and debated extensively. Following many decades of classical comparative morphology and embryology, the 1980s marked a turning point in studies of animal evolution, when molecular biological approaches, including molecular phylogeny (MP), molecular evolutionary developmental biology (evo-devo), and comparative genomics (CG), began to be employed. There are at least five key events in metazoan evolution, which include the origins of 1) diploblastic animals, such as cnidarians; 2) triploblastic animals or bilaterians; 3) protostomes and deuterostomes; 4) chordates, among deuterostomes; and 5) vertebrates, among chordates. The last two have received special attention in relation to evolution of human beings. During the past two decades, great advances have been made in this field, especially in regard to molecular and developmental mechanisms involved in the evolution of chordates. For example, the interpretation of phylogenetic relationships among deuterostomes has drastically changed. In addition, we have now obtained a large quantity of MP, evo-devo, and CG information on the origin and evolution of chordates. - Covers the most significant advances in this field to give readers an understanding of the interesting biological issues involved - Provides a unified presentation of essential information regarding each phylum and an integrative understanding of molecular mechanisms involved in the origin and evolution of chordates - Discusses the evolutionary scenario of chordates based on two major characteristic features of animals—namely modes of feeding (energy sources) and reproduction—as the two main forces driving animal evolution and benefiting dialogue for future studies of animal evolution
