Books in the Evolutionary Biology - New Perspectives on Its Development series

This book presents a unified evolutionary framework based on three sets of metaphors that will help to consolidate discussions on evolutionary transitions. Evolution is the unifying principle of life, making identifying ways to apply evolutionary principles to tackle existence-threatening crises such as climate change crucial.

This book is about evolutionary theory. It deals with aspects of its history to focus upon explanatory structures at work in the various forms of evolutionary theory - as such this is also a work of philosophy. Its focus lies on recent debates about the Modern Synthesis and what might be lacking in that synthesis. These claims have been most clearly made by those calling for an Extended Evolutionary Synthesis. The author argues that the difference between these two positions is the consequence of two things. First, whether evolution is a considered as solely a population level phenomenon or also a theory of form. Second, the use of information concepts.In this book Darwinian evolution is positioned as a general theory of evolution, a theory that gave evolution a technical meaning as the statistical outcome of variation, competition, and inheritance. The Modern Synthesis (MS) within biology, has a particular focus, a particular architecture to its explanations that renders it a special theory of evolution.After providing a history of Darwinian theory and the MS, recent claims and exhortations for an Extended Evolutionary Synthesis (EES) are examined that see the need for the inclusion of non-genetic modes of inheritance and also developmental processes. Much of this argument is based around claims that the MS adopts a particular view of information that has privileged the gene as an instructional unit in the emergence of form. The author analyses the uses of information and claims that neither side of the debate explicitly and formally deals with this concept. A more formal view of information is provided which challenges the EES claims about the role of genes in MS explanations of form whilst being consilient with their own interests in developmental biology. It is concluded that the MS implicitly assumed this formal view of information whilst using information terms in a colloquial manner. In the final chapter the idea that the MS is an informational theory that acts to corral more specific phenomenal accounts, is mooted. As such the book argues for a constrained pluralism within biology, where the MS describes those constraints.

This book contests the general view that natural selection constitutes the explanatory core of evolutionary biology. It invites the reader to consider an alternative view which favors a more complete and multidimensional interpretation.It is common to present the 1930-1960 period as characterized by the rise of the Modern Synthesis, an event structured around two main explanatory commitments: (1) Gradual evolution is explained by small genetic changes (variations) oriented by natural selection, a process leading to adaptation; (2) Evolutionary trends and speciational events are macroevolutionary phenomena that can be accounted for solely in terms of the extension of processes and mechanisms occurring at the previous microevolutionary level. On this view, natural selection holds a central explanatory role in evolutionary theory - one that presumably reaches back to Charles Darwin's Origin of Species - a view also accompanied by the belief that the field of evolutionary biology is organized around a profound divide: theories relying on strong selective factors and those appealing only to weak ones.If one reads the new analyses presented in this volume by biologists, historians and philosophers, this divide seems to be collapsing at a rapid pace, opening an era dedicated to the search for a new paradigm for the development of evolutionary biology. Contrary to popular belief, scholars' position on natural selection is not in itself a significant discriminatory factor between most evolutionists. In fact, the intellectual space is quite limited, if not non-existent, between, on the one hand, "Darwinists", who play down the central role of natural selection in evolutionary explanations, and, on the other hand, "non-Darwinists", who use it in a list of other evolutionary mechanisms.The "mechanism-centered" approach to evolutionary biology is too incomplete to fully make sense of its development. In this book the labels created under the traditional historiography - "Darwinian Revolution", "Eclipse of Darwinism", "Modern Synthesis", "Post-Synthetic Developments" - are thus re-evaluated.This book will not only appeal to researchers working in evolutionary biology, but also to historians and philosophers."
