| examples of non vertebrate chordates: Across the Bridge Henry Gee, 2018-07-04 “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 |

| examples of non vertebrate chordates: Evolving Neural Crest Cells Brian Frank Eames, Daniel Meulemans Medeiros, Igor Adameyko, 2020-07-28 Vertebrates possess lineage-specific characteristics. These include paired anterior sense organs and a robust, modular head skeleton built of cellular cartilage and bone. All of these structures are derived, at least partly, from an embryonic tissue unique vertebrates - the neural crest. The evolutionary history of the neural crest, and neural crest cells, has been difficult to reconstruct. This volume will use a comparative approach to survey the development of the neural crest in vertebrates, and neural crest-like cells, across the metazoa. This information will be used to reveal neural crest evolution and identify the genomic, genetic, and gene-regulatory changes that drove them. Key selling features: Summarizes the data regarding neural crest cells and nerural crest derivatives Uses a broad-based comparative approach Suggests hypothesis that the origin of neural crest cells involved the novel co-activation of ancient metazoan gene programs in neural border cells Illustrates how the emergences of neural crest made possible the diversification of vertebrate heads |

| examples of non vertebrate chordates: Cells in Evolutionary Biology Brian K. Hall, Sally A. Moody, 2018-06-12 This book is the first in a projected series on Evolutionary Cell Biology, the intent of which is to demonstrate the essential role of cellular mechanisms in transforming the genotype into the phenotype by transforming gene activity into evolutionary change in morphology. This book —Cells in Evolutionary Biology — evaluates the evolution of cells themselves and the role cells have been viewed to play as agents of change at other levels of biological organization. Chapters explore Darwin’s use of cells in his theory of evolution and how Weismann’s theory of the separation of germ plasm from body cells brought cells to center stage in understanding how acquired changes to cells within generations are not passed on to future generations.

| examples of non vertebrate chordates: Evolutionary Biology of Primitive Fishes R. E. Foreman, A. Gorbman, J. M. Dodd, R. Olsson, 2013-03-09 What, precisely, is a primitive fish? Most biologists would agree that the living cyclostomes, selachians, crossopterygians, etc. cannot be considered truly primitive. However, they and the fossil record have served to provide the information which forms the basis for speculation concerning the nature of the original vertebrates. This symposium of biologists from a variety of disciplines was called together to create collectively, from the best available current evidence, a picture of the probable line of evolution of the prototype primitive fishes. The symposium was designed to follow one that took place in Stockholm in 1967, convened for a similar purpose, with about the same number of participants. It is a matter of interest that almost the entire 1967 symposium (Nobel Symposium 4) dealt only with the hard tissues, whether fossil or modern. In charting the course of the present symposium it was felt that the intervening years have produced numerous lines of new evidence that could be employed in the same way that a navigator determines his position. Each field, be it adult morphology, geology, ecology, biochemistry, development or physiology, generates evidence that can be extrapolated backward from existing vertebrate forms and forward from invertebrate forms. If the intersect of only two lines of evidence produces a navigational fix of rather low reliability, then an intersect, however unfocussed, of multiple guidelines from more numerous disciplines might provide a better position from which to judge early vertebrate history. |

| examples of non vertebrate chordates: Evolution Wallace Arthur, 2010-03-11 This book is aimed at students taking courses on evolution in universities and colleges. Its approach and its structure are very different from previously-published evolution texts. The core theme in this book is how evolution works by changing the course of embryonic and post-embryonic development. In other words, it is an evolution text that has been very much influenced by the new approach of evolutionary developmental biology, or 'evo-devo'. Key themes include the following: developmental repatterning; adaptation and coadaptation; gene co-option; developmental plasticity; the origins of evolutionary novelties and body plans; and evolutionary changes in the complexity of organisms. As can be seen from this list, the book includes information across the levels of the gene, the organism, and the population. It also includes the issue of mapping developmental changes onto evolutionary trees. The examples used to illustrate particular points range widely, including animals, plants and fossils. I have really enjoyed reading this book. One of the strengths of the book is the almost conversational style. I found the style easy to read, but also feel that it will be invaluable in teaching. One of our tasks in university level teaching is to develop students' critical thinking skills. We need to support them in their intellectual development from a just the facts approach to being able to make critical judgements based on available evidence. The openness and honesty with which Arthur speaks to uncertainty in science is refreshing and will be a baseline for discussions with students. -Professor Patricia Moore, Exeter University This book, written as an undergraduate text, is a really most impressive book. Given the burgeoning interest in the role of developmental change in evolution in recent times, this will be a very timely publication. The book is well structured and, like the author's other books, very well written. He communicates with a clear, lucid style and has the ability to explain even the more difficult concepts in an accessible manner. ---Professor Kenneth McNamara, University of Cambridge The companion site can be found at www.wiley.com/go/arthur/evolution.

| examples of non vertebrate chordates: What Species Mean Julia D. Sigwart, 2018-10-29 Everyone uses species. All human cultures, whether using science or not, name species. Species are the basic units for science, from ecosystems to model organisms. Yet, there are communication gaps between the scientists who name species, called taxonomists or systematists, and those who use species names—everyone else. This book opens the black box of species names, to explain the tricks of the name-makers to the name-users. Species are real, and have macroevolutionary meaning, and it follows that systematists use a broadly macroevolution-oriented approach in describing diversity. But scientific names are used by all areas of science, including many fields such as ecology that focus on timescales more dominated by microevolutionary processes. This book explores why different groups of scientists understand and use the names given to species in very different ways, and the consequences for measuring and understanding biodiversity. Key selling features: Explains the modern, multi-disciplinary approach to studying species evolution and species discovery, and the role of species names in diverse fields throughout the life sciences Documents the importance and urgent need for high-quality taxonomic work to address today’s most pressing problems Summarises controversies in combining different—sometimes quite different—datasets used to estimate global biodiversity Focusses throughout on a central theme—the disconnect between the makers and the users of names—and seeks to create the rhetorical foundation needed to bridge this disconnect Anticipates the future of taxonomy and its role in studies of global biodiversity |

| examples of non vertebrate chordates: Origins of Human Neuropathology: The Significance of Teneurin-Latrophilin Interaction David A. Lovejoy, Antony A. Boucard, Richard P. Tucker, 2020-07-22 We are delighted to introduce this new special issue on “The Origins of Neuropathology: The Roles of Teneurins and Latrophilins”. Although the title may seem particularly bold, and indeed, perhaps presumptuous, we the editors, think our title well warranted based on the findings and interpretation provided by a dedicated group of researchers who have developed this field over the last 25 years. In this publication, we introduce the readers to researchers whom have pioneered this field, and those whom have played an essential role in developing this research direction. Now, together, their combined work have elucidated a novel ligandreceptor network that evolved during the earliest period of animal evolution, and has fostered a new insight into the ancient evolutionary organization of the central nervous system (CNS). Specifically, this work offers a new understanding of several aspects of neuropathology including degenerative, psychiatric and mood disorders and, furthermore, illuminates a fundamental role that teneurins and latrophilins play in cell-to-cell metabolism that may be associated with various forms of cancer both within and outside of the brain. In 1994, the laboratories of Professors Ron Wides in Israel and Ruth Chiquet-Ehrismann working in Switzerland, independently reported the existence of a novel transmembrane protein and its gene in Drosophila. A complex gene/protein, its closest homologue was that of the tenascins. The gene was named either odd oz (odz) or tenascin major (ten-m) by these researchers. Subsequent studies indicated that the gene was highly expressed in the brains of vertebrates and the term ‘teneurin’ was coined to reflect both its relationship with tenascins and with the CNS. Around the same time as these studies, a novel G protein-coupled receptor was identified by Yuri Ushkaryov and his team in the United Kingdom (in fact the latrophilins then named CIRL, calcium-independent receptor for a-latrotoxin, was first identified by the group of Petrenko at NYU Medical Center in New York, USA), which was subsequently established as a cognate receptor for the teneurins. This receptor was later termed as the latrophilins and more recently ‘Adhesion receptor G-protein coupled receptor, family L or ADGRL. In Part 1 of this publication, the early history on the origin and discovery of teneurins has been described by Stefan Baumgartner and Ron Wides; Ron Wides; and Richard Tucker. Recent structural studies by Verity Jackson and her colleagues, as well as Demet Arae¸ and Jingxian Li have provided molecular models to understand how teneurins are ensconced in the plasma membrane and play a role in synaptic interaction. In addition, their work integrates the molecular mechanisms with the early evolution of both teneurins and latrophilins. In Part 2, four studies build upon the evolutionary development of teneurins by examining its role in nematodes by Ulrike Topf and Krzysztof Drabikowski, a model of teneurin action in the Drosophilia nervous system by Alison DePew and associates; and two studies on fish. Angela Cheung and her colleagues describe the neurological function and expression in zebrafish, whereas Ross Reid and his coworkers have described novel actions of the teneurins with respect to metabolism in fish. Part 3 of this publication is focused on the latrophilins and is led off by Yuri Ushkaryov and his team describing the discovery, structure and function of the latrophilins. This work is followed by a review by Ana Moreno-Salinas and colleagues in Antony Boucard´s laboratory describing the structure of the latrophilins and its interaction with associated transmembrane proteins with respect to adhesion, neuronal function and pathology. The following paper, by Torsten Schönberg and Simone Prömel links the previous papers with a comparison of teneurin and latrophilin interactions in invertebrates and vertebrates. Finally, in this section, Peter Burbach and Dimphna Meijer provide an interesting overview of the relationship of teneurins and latrophilins with respect to other proteins described in these other papers. Together, these studies provide a novel understanding of how the teneurins and latrophilins interact in a complex set of associated proteins. The next section (Part 4) of the publication focuses on the development and maintenance of the CNS in mammals. Here, Catherine Leamey and Atomu Sawatari lead off with a discussion of the role of teneurin-associated neuro-circuit formation using knockout studies in mice. A detailed review by Luciane Sita and her colleagues in the Bittencourt laboratory frames this and previous studies in a comparative neuroanatomical background, and in addition, provides a neuroanatomical rationale for new studies associated with other regions of the CNS. Building upon these studies, David Hogg and his coworkers include a review on the behavioral actions of the teneurin C-terminal associated peptide (TCAP) in mammals and its potential relationship to brain metabolism and forms of neuropathology. Finally, in this section, a study by Gesttner Tessarin in the Casatti laboratory shows for the first time, teneurins may be associated with astrocyte function, indicating a novel function for teneurins with respect to some glial-based disorders in the brain. Finally in our last section, we have provided some studies on the potential roles of the teneurins and latrophilins with respect to carcinogenesis. Although these studies are somewhat removed from our treatise on the role of teneurins and latrophilins with respect to neuronal development, maintenance and pathology, they provide interesting observations that may be relevant to some types of CNS pathology. Thus, Boris Rebolledo-Jaramillo and Annemarie Ziegler include a review on the relationship of teneurins to several types of cancers. This is followed by a research report by Mia Husić and her colleagues suggesting that the TCAP region of the teneurins could play a role in modulating the adhesion of the cancer-like cell line, HEK293 and finally, Sussy Bastias-Candia and associates have provided novel data on the role of teneurin-3 with respect to Wnt signalling and have discussed its potential role in neural development and carcinogenesis. Overall, we posit that the teneurins and latrophilins played a major role in the early evolution of the nervous system and may underlie the etiology of a number of neurological disorders that are thus-far misunderstood. Indeed, we hope that this publication will stimulate further research into the actions of teneurins and latrophilins and lead to novel approaches of understanding and ultimately treatment. Obituary: Ruth Chiquet-Ehrismann (1954-2015): A Teneurin Pioneer A major player in the discovery and characterization of teneurins was the Swiss scientist, Ruth Chiquet-Ehrismann. Dr. Chiquet-Ehrismann had a long-standing interest in cell-cell and cell-extracellular matrix interactions, particularly during development and tumorigenesis. She earned her Ph.D. at the ETH Zurich under the mentorship of David C. Turner, where she performed early work on the cell and heparin-binding sites of fibronectin. Shortly after joining the Friedrich Miescher Institute in Basel as a junior group leader in 1984, Ruth, in collaboration with Eleanor J. Mackie and Teruyo Sakakura, published a paper in Cell describing an extracellular matrix glycoprotein that she named “tenascin”. A key observation made in this widely cited paper was the presence of tenascin in the extracellular matrix of embryonic tissues and the stroma of breast cancer, but its absence from most normal adult tissues. We now know that the original “tenascin” was the founding member of a diverse gene family, and that members of this family promote cell motility, proliferation and differentiation in a variety of tissue environments, both normal and pathological. But in the early 1990s, it was unclear how tenascins functioned. Specifically, its receptors and binding partners were not understood. Subsequently, Ruth engaged in a multi-pronged approach to studying tenascin function in an attempt to identify its homologues in Drosophila. This work, led by her postdoctoral fellow Dr. Stefan Baumgartner, resulted in the discovery of a novel family of type-2 transmembrane proteins that they named ten-a and ten-m, for “tenascin-like proteins accessory and major”. When the homologues of ten-a and ten-m were found in vertebrates and they were shown to be highly expressed in the nervous system, Ruth proposed the name “teneurins”. This name combined the names of the original proteins from Drosophila with neurons, which appeared to be their most prominent site of expression. From that point onward, Ruth’s research group at the Friedrich Miescher Institute studied two topics: the roles of tenascins in cancer and the roles of teneurins in development. Using numerous model systems, her research included studies of teneurins in arthropods (Drosophila), nematodes (C. elegans) and chordates (birds and humans). Key firsts that came from Ruth’s laboratory include the cloning and sequencing of human teneurins, experimental evidence of teneurin processing by furin and the potential nuclear localization of the intracellular domain, the ability of teneurins to promote growth cone spreading, patterning defects in teneurin knockout animals, a description of the ancient origins of teneurins via horizontal gene transfer, the complementary expression patterns of different teneurins during development, the cytotoxic properties of the teneurin C-terminal domain, and the presence of homotypic adhesion domains in teneurins. Since 1994, Ruth’s group published 24 papers on the cloning, expression, origins and functions of teneurins. Contributing to these papers were 15 graduate students and postdoctoral fellows, often with the expert technical guidance of Jacqueline Ferralli, Marianne Brown-Luedi and Doris Martin. This work has provided a foundation for a new generation of researchers in the field of teneurins. Ruth Chiquet-Ehrismann passed away at her home near Basel on September 4, 2015. She is survived by her husband and collaborator Matthias Chiquet, three children, Daniel, Patrice and Fabian, and an expanding cohort of grandchildren. Richard P. Tucker Davis, California |

Part Two is the survey of protists and animals, emphasizing evolutionary and ecological relationships, aspects of animal organization that unite major animal phyla, and animal adaptations. Part Three covers animal form and function using a comparative approach. This approach includes descriptions and full-color artwork that depict evolutionary changes in the structure and function of selected organ systems. |
| examples of non vertebrate chordates: Evolving Animals Wallace Arthur, 2014-08-07 What do we know about animal evolution in the early twenty-first century? How much more do we know today than Darwin did? What are the most exciting discoveries that have been made in the last few decades? Covering all the main animal groups, from jellyfish to mammals, this book considers all of these questions and more. Its 30 short chapters, each written in a conversational, nontechnical style and accompanied by numerous original illustrations, deal equally with the pattern and the process of evolution - with both evolutionary trees and evolutionary mechanisms. They cover diverse evolutionary themes, including: the animal toolkit, natural selection, embryos and larvae, animal consciousness, fossils, human evolution, and even the possibility of animal life existing elsewhere than on Earth. This unique text will make an excellent introduction for undergraduates and others with an interest in the subject. |
| examples of non vertebrate chordates: Polyploidy and Genome Evolution Pamela S. Soltis, Douglas E. Soltis, 2012-10-03 Polyploidy – whole-genome duplication (WGD) – is a fundamental driver of biodiversity with significant consequences for genome structure, organization, and evolution. Once considered a speciation process common only in plants, polyploidy is now recognized to have played a major role in the structure, gene content, and evolution of most eukaryotic genomes. In fact, the diversity of eukaryotes seems closely tied to multiple WGDs. Polyploidy generates new genomic interactions – initially resulting in “genomic and transcriptomic shock” – that must be resolved in a new polyploid lineage. This process essentially acts as a “reset” button, resulting in genomic changes that may ultimately promote adaptive speciation. This book brings together for the first time the conceptual and theoretical underpinnings of polyploid genome evolution with syntheses of the patterns and processes of genome evolution in diverse polyploid groups. Because polyploidy is most common and best studied in plants, the book emphasizes plant models, but recent studies of vertebrates and fungi are providing fresh perspectives on factors that allow polyploid speciation and shape polyploid genomes. The emerging paradigm is that polyploidy – through alterations in genome structure and gene regulation – generates genetic and phenotypic novelty that manifests itself at the chromosomal, physiological, and organismal levels, with long-term ecological and evolutionary consequences. |

| examples of non vertebrate chordates: Exploring Biology in the Laboratory: Core Concepts Murray P. Pendarvis, John L. Crawley, 2019-02-01 Exploring Biology in the Laboratory: Core Concepts is a comprehensive manual appropriate for introductory biology lab courses. This edition is designed for courses populated by nonmajors or for majors courses where abbreviated coverage is desired. Based on the two-semester version of Exploring Biology in the Laboratory, 3e, this Core Concepts edition features a streamlined set of clearly written activities with abbreviated coverage of the biodiversity of life. These exercises emphasize the unity of all living things and the evolutionary forces that have resulted in, and continue to act on, the diversity that we see around us today. |
