Book Description
Constructional morphology explains features of organisms from a constructional and functional point of view. By means of physical analysis it explains the operational aspects of organic structures - how they can perform the activities organisms are expected to fulfil in order to survive in their environment. Constructional morphology also explains options and constraints during the evolution determined by internal constructional needs, ontogenetic demands, inherited organizational preconditions and environmental clues.

Book Description
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.

Book Description
Did Darwin see evolution as progressive, directed toward producing ever more advanced forms of life? Most contemporary scholars say no. In this challenge to prevailing views, Robert J. Richards says yes—and argues that current perspectives on Darwin and his theory are both ideologically motivated and scientifically unsound. This provocative new reading of Darwin goes directly to the origins of evolutionary theory. Unlike most contemporary biologists or historians and philosophers of science, Richards holds that Darwin did concern himself with the idea of progress, or telos, as he constructed his theory. Richards maintains that Darwin drew on the traditional embryological meanings of the terms "evolution" and "descent with modification." In the 1600s and 1700s, "evolution" referred to the embryological theory of preformation, the idea that the embryo exists as a miniature adult of its own species that simply grows, or evolves, during gestation. By the early 1800s, however, the idea of preformation had become the concept of evolutionary recapitulation, the idea that during its development an embryo passes through a series of stages, each the adult form of an ancestor species. Richards demonstrates that, for Darwin, embryological recapitulation provided a graphic model of how species evolve. If an embryo could be seen as successively taking the structures and forms of its ancestral species, then one could see the evolution of life itself as a succession of species, each transformed from its ancestor. Richards works with the Origin and other published and archival material to show that these embryological models were much on Darwin's mind as he considered the evidence for descent with modification. Why do so many modern researchers find these embryological roots of Darwin's theory so problematic? Richards argues that the current tendency to see evolution as a process that is not progressive and not teleological imposes perspectives on Darwin that incorrectly deny the clearly progressive heart of his embryological models and his evolutionary theory.

Book Description
In the final decades of the twentieth century, the advent of evolutionary developmental biology (evo-devo) offered a revolutionary new perspective that transformed the classical neo-Darwinian, gene-centered study of evolution. In The Architecture of Evolution, Marco Tamborini demonstrates how this radical innovation was made possible by the largely forgotten study of morphology. Despite the key role morphology played in the development of evolutionary biology since the 1940s, the architecture of organisms was excluded from the Modern Evolutionary Synthesis. And yet, from the beginning of the twentieth century to the 1970s and ’80s, morphologists sought to understand how organisms were built and how organismal forms could be generated and controlled. The generation of organic form was, they believed, essential to understanding the mechanisms of evolution. Tamborini explores how the development of evo-devo and the recent organismal turn in biology involved not only the work of morphologists but those outside the biological community with whom they exchanged their data, knowledge, and practices. Together with architects and engineers, they worked to establish a mathematical and theoretical basis for the study of organic form as a mode of construction, developing and reinterpreting important notions that would play a central role in the development of evolutionary developmental biology in the late 1980s. This book sheds light not only on the interdisciplinary basis for many of the key concepts in current developmental biology but also on contributions to the study of organic form outside the English-speaking world.

Book Description
Why do living organisms have the designs (and especially the skeletons) that they actually possess? Is it possible, and legitimate, to infer from the fossilised remains of a long-dead creature how it functioned as a living system, with all the components operating together in harmony? Some 40 years ago there was an often stated view that studies of functional morphology in fossil animals could never be more than clever speculation. Yet as time went by, it became increasingly clear that functional interpretations, when carried out in the right way, were indeed a proper field for study in palaeontology, and that animal skeletons, of almost any kind, could yield definitive information about how their bearers had lived. We need first to consider the origins of animal skeletons. There are two important factors here. The first is contingency, in other words the 'accidents of history'', which established suites of body plans which could subsequently be modified in different ways. Yet as ROGER THOMAS and WOLF-ERNST REIF pointed out in their 'Skeleton-Space'' model (1993), there are confining physico-chemical constratints which thereafter determine evolutionary pathways. There are, in fact, only a limited number of ways in which a skeleton can be functional, as determined by the properties of the material of which it is constructed, constraints upon growth and development, and the requirement for its component parts to function in terms of the whole organism. In consequence "the discovery of 'good'' designs  those that are viable and that can be constructed with available materials  was inevitable, and in principle predictable ... the recurring designs we observed are attractors, orderly and stable configurations of matter that must necessarily emerge in the course of evolution" (THOMAS & REIF 1993). Where then, with this in mind, do we proceed from here? Amongst compendia regarding form and function in fossils, we have the recent Functional Morphology of the Invertebrate Skeleton (1999), a fine collection of 43 papers edited by ENRICO SAVAZZI. Here one finds both specialised case histories and encompassing reviews, dealing with many kinds of invertebrate, and very useful it is regarding the various ways in which invertebrate palaeontologists study their fossils as living organisms. But the present volume is something different, for it encapsulates the refreshingly individual approach which has emerged in Germany over the last several years, most vigorously articulated by MICHAEL GUDO and his colleagues at the Senckeneberg Institute, Frankfurt am Main. Their basic concept is that the structural and functional constraints on living organisms can best be interpreted in terms of engineering analogues. Mechanical engineering, after all is about how machines are constructed and how they work, and there are simple analogues all around us. Consider, for a moment the evident correspondence between the claw of a crab and a pair of pincers, or an arthropod limb and the arm of a mechanical digger. There are surely many useful insights to be derived from an understanding of engineering principles, and the research papers collected in the present volume are a testament to the vigour of this approach. For herein we find not only concepts, but also tools and techniques in common use in engineering applied to biomechanics; computer-aided design and tomography, landmark analysis, Finite Element Analysis, and CAT-scans. Such tools give a much greater objectivity to analysis of function, for it is true enough, as Carpenter comments in this volume, that 'theoretical models are often tainted with preconcieved ideas''. There are thirty papers in five sections, each of which consists of several papers, and at the beginning of each section is an explanatory introduction and summary. Section 1, Functional morphology and biomechanics. Following introductory comments by GUDO et al., there are six papers all concerned with vertebrates, and especially dinosaurs. T

Book Description
This book considers the evolution of the grammatical structure of words in the more general contexts of human evolution and the origins of language. The consensus in many fields is that language is well designed for its purpose, and became so either through natural selection or by virtue of non-biological constraints on how language must be structured. Andrew Carstairs-McCarthy argues that in certain crucial respects language is not optimally designed. This can be seen, he suggests, in the existence of not one but two kinds of grammatical organization - syntax and morphology - and in the morphological and morpho-phonological complexity which leads to numerous departures from the one-form-one-meaning principle. Having discussed the issue of good and bad design in a wider biological context, the author shows that conventional explanations for the nature of morphology do not work. Its poor design features arose, he argues, from two characteristics present when the ancestors of modern humans had a vocabulary but no grammar. One of these was a synonymy-avoidance expectation, while the other was an articulatory and phonological apparatus that encouraged the development of new synonyms. Morphology developed in response to these conflicting pressures. In this stimulating and carefully argued account Professor McCarthy offers a powerful challenge to conventional views of the relationship between syntax and morphology, to the adaptationist view of language evolution, and to the notion that language in some way reflects 'laws of form'. This fundamental contribution to understanding the nature and evolution of language will be of wide interest to linguists of all theoretical persuasions as well as to scholars in cognitive science and anthropology.

Book Description
This volume is the result of a NATO Advanced Study Institute held in England at Kingswood Hall of Residence, Royal Holloway College (London University), Surrey, during the last two weeks of July, 1976. The ASI was organized within the guide lines laid down by the Scientific Affairs Division of the North Atlantic Treaty Organization. During the past two decades, significant advances have been made in our understanding of vertebrate evolution. The purpose of the Institute was to present the current status of our know ledge of vertebrate evolution above the species level. Since the subject matter was obviously too broad to be covered adequately in the limited time available, selected topics, problems, and areas which are applicable to vertebrate zoology as a whole were reviewed. The program was divided into three areas: (1) the theory and methodology of phyletic inference and approaches to the an alysis of macroevolutionary trends as applied to vertebrates; (2) the application of these methodological principles and an alytical processes to different groups and structures, particular ly in anatomy and paleontology; (3) the application of these re sults to classification. The basic principles considered in the first area were outlined in lectures covering the problems of character analysis, functional morphology, karyological evidence, biochemical evidence, morphogenesis, and biogeography.
