Download or read book The Epigenetic Nature of Early Chordate Development written by Pieter D. Nieuwkoop and published by CUP Archive. This book was released on 1985-08-15 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume summarises our present knowledge of inductive interaction during early development of various groups of chordates. Embryonic development is mainly epigenetic, that is, each embryo arises through gradual organisation and emergence of its constituent parts and not by the unfolding of preformed structures. Development as far as the full development of the 'body plan' in the embryo is described. At the beginning of development, there is only very restricted spatial diversity, but as development proceeds the interaction of the different parts leads to ever-increasing spatial complexity of the developing embryo. Interaction starts between the different cell organelles of the oocyte and the, spermatozoon; it continues without interruption between the different parts of the very early embryo and also between the different tissues and organ anlagen of the developing embryo. The new hypothesis as to the nature of the inductive interaction, which is postulated here, is in good agreement with the experimental evidence presented and opens new possibilities for fruitful research into this basic concept of embryonic development.
Download or read book Morphodynamics written by Adolf Seilacher and published by CRC Press. This book was released on 2014-11-05 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: Morphodynamics is defined as the unique interaction among environment, functional morphology, developmental constraints, phylogeny, and time—all of which shape the evolution of life. These fabricational patterns and similarities owe their regularity not to a detailed genetic program, but to extrinsic factors, which may be mechanical, chemical, or biological in nature. These self-organizing mechanisms are the focus of Morphodynamics. Illustrated by numerous examples from across the biological spectrum, this book embodies the foundation of noted paleontologist Adolf Seilacher’s thinking on the study of morphodynamics. It represents his unique approach of presenting paleontology from an ecological and constructional perspective, rather than a purely taxonomic one. The hallmark of Seilacher’s storied career has been a constructional and functional focus. He begins by discussing the basic principles—form, pattern formation, ecology and evolution, as well as the factors that override those processes. Next, he examines how morphodynamic principles are implemented in various invertebrates including single-celled protists, Ediacarans, sponges, coelenterates, shelled organisms, worms, arthropods, and echinoderms. The final chapter explores how morphogenetic principles may apply to clonal colonial organisms. Summarizing seventy years of research into the interactions of form, function, and evolution, the book is copiously illustrated with the author’s own distinctive drawings and an abundance of photos. It provides a framework for readers to pose their own questions and sharpen their interpretive skills on this fascinating topic.

Download or read book The Runes of Evolution written by Simon Conway Morris and published by Templeton Foundation Press. This book was released on 2015-06-30 with total page 525 pages. Available in PDF, EPUB and Kindle. Book excerpt: How did human beings acquire imaginations that can conjure up untrue possibilities? How did the Universe become self-aware? In The Runes of Evolution, Simon Conway Morris revitalizes the study of evolution from the perspective of convergence, providing us with compelling new evidence to support the mounting scientific view that the history of life is far more predictable than once thought. A leading evolutionary biologist at the University of Cambridge, Conway Morris came into international prominence for his work on the Cambrian explosion (especially fossils of the Burgess Shale) and evolutionary convergence, which is the process whereby organisms not closely related (not monophyletic), independently evolve similar traits as a result of having to adapt to similar environments or ecological niches. In The Runes of Evolution, he illustrates how the ubiquity of convergence hints at an underlying framework whereby many outcomes, not least brains and intelligence, are virtually guaranteed on any Earth-like planet. Conway Morris also emphasizes how much of the complexity of advanced biological systems is inherent in microbial forms. By casting a wider net, The Runes of Evolution explores many neglected evolutionary questions. Some are remarkably general. Why, for example, are convergences such as parasitism, carnivory, and nitrogen fixation in plants concentrated in particular taxonomic hot spots? Why do certain groups have a particular propensity to evolve toward particular states? Some questions lead to unexpected evolutionary insights: If bees sleep (as they do), do they dream? Why is that insect copulating with an orchid? Why have sponges evolved a system of fiber optics? What do mantis shrimps and submarines have in common? If dinosaurs had not gone extinct what would have happened next? Will a saber-toothed cat ever re-evolve? Cona Morris observes: “Even amongst the mammals, let alone the entire tree of life, humans represent one minute twig of a vast (and largely fossilized) arborescence. Every living species is a linear descendant of an immense string of now-vanished ancestors, but evolution itself is the very reverse of linear. Rather it is endlessly exploratory, probing the vast spaces of biological hyperspace. Indeed this book is a celebration of how our world is (and was) populated by a riot of forms, a coruscating tapestry of life.” The Runes of Evolution is the most definitive synthesis of evolutionary convergence to be published to date.

Download or read book Biology and Evolution of Crocodylians written by Gordon Grigg and published by CSIRO PUBLISHING. This book was released on 2015-01-15 with total page 671 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biology and Evolution of Crocodylians is a comprehensive review of current knowledge about the world's largest and most famous living reptiles. Gordon Grigg's authoritative and accessible text and David Kirshner's stunning interpretive artwork and colour photographs combine expertly in this contemporary celebration of crocodiles, alligators, caimans and gharials. This book showcases the skills and capabilities that allow crocodylians to live how and where they do. It covers the biology and ecology of the extant species, conservation issues, crocodylian–human interaction and the evolutionary history of the group, and includes a vast amount of new information; 25 per cent of 1100 cited publications have appeared since 2007. Richly illustrated with more than 500 colour photographs and black and white illustrations, this book will be a benchmark reference work for crocodylian biologists, herpetologists and vertebrate biologists for years to come.
