This essay is a response to Denis Noble’s argument that the evolutionary synthesis was based on illusory science and that it itself is a kind of illusion. The response includes an historical examination of the relationship between evolutionary biology and molecular biology, along with the importance of history in evolutionary biology, which is an historical science. It raises concerns about adherence to one standard evolutionary theory, and urges the reader to consider a more contextualist and historicist (...) approach, one that adopts a more pluralistic view of evolutionary theory. It ends with the provocative question of what evolution would mean if it had no history. (shrink)
No other scientific theory has had as tremendous an impact on our understanding of the world as Darwin's theory as outlined in his Origin of Species, yet from the very beginning the theory has been subject to controversy. The Evolution of Darwinism focuses on three issues of debate - the nature of selection, the nature and scope of adaptation, and the question of evolutionary progress. It traces the varying interpretations to which these issues were subjected from the beginning and (...) the fierce contemporary debates that still rage on and explores their implications for the greatest questions of all: Where we come from, who we are and where we might be heading. Written in a clear and non-technical style, this book will be of use as a textbook for students in the philosophy of science who need to become familiar with the background to the debates about evolution.

“I often said before starting, that I had no doubt I should frequently repent of the whole undertaking.” So wrote Charles Darwin aboard The Beagle , bound for the Galapagos Islands and what would arguably become the greatest and most controversial discovery in scientific history. But the theory of evolution did not spring full-blown from the head of Darwin. Since the dawn of humanity, priests, philosophers, and scientists have debated the origin and development of life on earth, and (...) with modern science, that debate shifted into high gear. In this lively, deeply erudite work, Pulitzer Prize–winning science historian Edward J. Larson takes us on a guided tour of Darwin’s “dangerous idea,” from its theoretical antecedents in the early nineteenth century to the brilliant breakthroughs of Darwin and Wallace, to Watson and Crick’s stunning discovery of the DNA double helix, and to the triumphant neo-Darwinian synthesis and rising sociobiology today. Along the way, Larson expertly places the scientific upheaval of evolution in cultural perspective: the social and philosophical earthquake that was the French Revolution; the development, in England, of a laissez-faire capitalism in tune with a Darwinian ethos of “survival of the fittest”; the emergence of Social Darwinism and the dark science of eugenics against a backdrop of industrial revolution; the American Christian backlash against evolutionism that culminated in the famous Scopes trial; and on to today’s world, where religious fundamentalists litigate for the right to teach “creation science” alongside evolution in U.S. public schools, even as the theory itself continues to evolve in new and surprising directions. Throughout, Larson trains his spotlight on the lives and careers of the scientists, explorers, and eccentrics whose collaborations and competitions have driven the theory of evolution forward. Here are portraits of Cuvier, Lamarck, Darwin, Wallace, Haeckel, Galton, Huxley, Mendel, Morgan, Fisher, Dobzhansky, Watson and Crick, W. D. Hamilton, E. O. Wilson, and many others. Celebrated as one of mankind’s crowning scientific achievements and reviled as a threat to our deepest values, the theory of evolution has utterly transformed our view of life, religion, origins, and the theory itself, and remains controversial, especially in the United States (where 90% of adults do not subscribe to the full Darwinian vision). Replete with fresh material and new insights, Evolution will educate and inform while taking readers on a fascinating journey of discovery. (shrink)
What is the relationship of history to the phylogenetic evolution of man? Historians, like all specialists, are wont to restrict themselves to their own problems and, therefore, do not deal with this question. Only some popular books on the history of the world cross the dividing line between social and natural science. They start with the origin of the solar system, describe the development of the crust of the earth and of life, turn to prehistoric civilization and (...) ancient Egypt, and eventually finish with the history of present times. It is striking that those expositions become more and more detailed the nearer they come to their end. Near the beginning one page describes ten million years, near the end ten months. (shrink)
This book tells the history of the many analogies that have been made between the evolution of organisms and the human production of artefacts, especially buildings. It examines the effects of these analogies on architectural and design theory and considers how recent biological thinking has relevance for design. Architects and designers have looked to biology for inspiration since the early 19th century. They have sought not just to imitate the forms of plants and animals, but to find (...) methods in design analogous to the processes of growth and evolution in nature. This new revised edition of this classic work adds an extended Afterword covering recent developments such as the introduction of computer methods in design in the 1980s and ‘90s, which have made possible a new kind of ‘biomorphic’ architecture through ‘genetic algorithms’ and other programming techniques.

In fact, analogy is a legitimate form of comparison, and comparison is the only practical means we have for the understanding of things. The fault of the biological sociologists was not that they used it but that they used it wrongly. Instead of trying to control their studies of society by their knowledge of biol ogy, they tried to infer the laws of the first from the laws of the second.
Progress Unchained reinterprets the history of the idea of progress using parallels between evolutionary biology and changing views of human history. Early concepts of progress in both areas saw it as the ascent of a linear scale of development toward a final goal. The 'chain of being' defined a hierarchy of living things with humans at the head, while social thinkers interpreted history as a development toward a final paradise or utopia. Darwinism reconfigured biological progress as (...) a 'tree of life' with multiple lines of advance not necessarily leading to humans, each driven by the rare innovations that generate entirely new functions. Popular writers such as H. G. Wells used a similar model to depict human progress, with competing technological innovations producing ever-more rapid changes in society. Bowler shows that as the idea of progress has become open-ended and unpredictable, a variety of alternative futures have been imagined. (shrink)
When phenomenology was introduced as a new science by Husserl its methods were applied first to objects of logic. Later phenomenological investigation expanded gradually to the fields of psychology, ethics, esthetics, and sociology. More rarely, objects of the natural sciences have been treated phenomenologically. Scattered indications of this kind are to be found in authors who do not belong to the most intimate circle of Husserl's school. Extensively, however, the phenomenological method has been applied to objects of the natural sciences (...) once only, namely by Hedwig Conrad-Martius, a favorite pupil of Husserl's, in her Realontologie and Farben. Yet this less known branch of phenomenology is particularly interesting. Husserl stressed the basic difference between phenomenological ideation on the one hand and psychological introspection and description of the immediate data of awareness on the other. The peculiarity and scientific productivity of phenomenological method, therefore, can be studied best in a field which is as far removed from psychology as possible. We shall try to analyze the papers of Conrad-Martius more fully and shall refer to other authors occasionally as illustrations. (shrink)
This collection of thirteen essays by prominent scholars explores the history of evolutionary thought in all of its cultural richness over the past two hundred years. Evolutionary ideas have undergone fundamental changes and are now found to have diverse sources and universal scope. They are no longer beholden to biologists’ understanding of their own past, and do not focus exclusively on Charles Darwin. This volume aims to address the problem of the human significance of evolution. The contributors draw (...) on contemporary sources as diverse as medicine, literature and natural history tableaux, as well as the resources of publishing history, feminine scholarship, and the histories of politics, sociology, and philosophy. The essays offer new perspectives on familiar figures such as Erasmus, Charles Darwin, Lamarck, Chambers, Huxley, and Haeckel, but also on many lesser known participants in the evolutionary debates.

Ideas about heredity and evolution are undergoing a revolutionary change. New findings in molecular biology challenge the gene-centered version of Darwinian theory according to which adaptation occurs only through natural selection of chance DNA variations. In Evolution in Four Dimensions, Eva Jablonka and Marion Lamb argue that there is more to heredity than genes. They trace four "dimensions" in evolution -- four inheritance systems that play a role in evolution: genetic, epigenetic, behavioral, and symbolic. These (...) systems, they argue, can all provide variations on which natural selection can act. Evolution in Four Dimensions offers a richer, more complex view of evolution than the gene-based, one-dimensional view held by many today. The new synthesis advanced by Jablonka and Lamb makes clear that induced and acquired changes also play a role in evolution.After discussing each of the four inheritance systems in detail, Jablonka and Lamb "put Humpty Dumpty together again" by showing how all of these systems interact. They consider how each may have originated and guided evolutionary history and they discuss the social and philosophical implications of the four-dimensional view of evolution. Each chapter ends with a dialogue in which the authors engage the contrarieties of the fictional "I.M.," or Ifcha Mistabra -- Aramaic for "the opposite conjecture" -- refining their arguments against I.M.'s vigorous counterarguments. The lucid and accessible text is accompanied by artist-physician Anna Zeligowski's lively drawings, which humorously and effectively illustrate the authors' points. (shrink)
Biology seems to present local and transitory regularities rather than immutable laws. To account for these historically constituted regularities and to distinguish them from mathematical invariants, Montévil and Mossio have proposed to speak of constraints. In this article we analyse the causal power of these constraints in the evolution of biodiversity, i.e., their positivity, but also the modality of their action on the directions taken by evolution. We argue that to fully account for the causal power of (...) these constraints on evolution, they must be thought of in terms of normativity. In this way, we want to highlight two characteristics of the evolutionary constraints. The first, already emphasised as reported by Gould, is that these constraints are both produced by and producing biological evolution and that this circular causation creates true novelties. The second is that this specific causality, which generates unpredictability in evolution, stems not only from the historicity of biological constraints, but also from their internalisation through the practices of living beings.

This book offers to the international reader a collection of original articles of some of the most skillful historians and philosophers of biology currently working in Latin American universities. During the last decades, increasing attention has been paid in Latin America to the history and philosophy of biology, but since many local authors prefer to write in Spanish or in Portuguese, their ideas have barely crossed the boundaries of the continent. This volume aims to remedy this state (...) of things, providing a good sample of this production to the English speaking readers, bringing together contributions from researchers working in Brazilian, Argentinean, Chilean, Colombian and Mexican universities. The stress on the regional provenance of the authors is not intended to suggest the existence of something like a Latin American history and philosophy of biology, supposedly endowed with distinctive features. On the contrary, the editors firmly believe that advances in this field can be achieved only by stimulating the integration in the international debate. Based on this assumption, the book focuses on two topics, life and evolution, and presents a selection of contributions addressing issues such as the history of the concept of life, the philosophical reflection on life manipulation and life extension, the structure and development of evolutionary theory as well as human evolution. Life and Evolution – Latin American Essays on the History and Philosophy of Biology will provide the international reader with a rather complete picture of the ongoing research in the history and philosophy of biology in Latin America, offering a snapshot of this dynamic community. It will also contribute to contextualize and develop the debate concerning life and evolution, and the relation between the two phenomena. (shrink)
Wim van der Steen charts the conceptual foundations of evolutionary theory and evaluates applications of the theory. Conceptual analysis shows that evolutionary theory is a body of interesting natural history at a low level of generality. Asserting that laws of evolution do not exist, he shows that evolutionary approaches do not allow for sweeping claims about man.
A large body of work in science education indicates that evolution is one of the least understood and accepted scientific theories. Although scholarship from the history and philosophy of science (HPS) has shed light on many conceptual and pedagogical issues in evolution education, HPS-informed studies of evolution education are also characterized by conceptual weaknesses. In this chapter, we critically review such studies and find that some work lacks historically accurate characterizations of student ideas (preconceptions and misconceptions). (...) In addition, although several studies in the science education literature have drawn parallels between students’ conceptual change patterns and those from the history of science (HOS), we identify several issues that complicate the characterization of student ideas as “Lamarckian” or “Darwinian.” Finally, a review of the topic of explanation illustrates how the plurality of approaches employed in evolutionary biology is not reflected in evolution education scholarship or practice. This finding is particularly concerning given the recent shift in emphasis in science education standards to teaching content through practice-based tasks (e.g., explanation and argumentation). Overall, this chapter demonstrates that while HPS is of central importance to a deep understanding of evolution education, too often its contributions are poorly realized. (shrink)
This volume explores questions about conceptual change from both scientific and philosophical viewpoints by analyzing the recent history of evolutionary developmental biology. It features revised papers that originated from the workshop "Conceptual Change in Biological Science: Evolutionary Developmental Biology, 1981-2011" held at the Max Planck Institute for the History of Science in Berlin in July 2010. The Preface has been written by Ron Amundson. In these papers, philosophers and biologists compare and contrast key concepts in evolutionary (...) developmental biology and their development since the original, seminal Dahlem conference on evolution and development held in Berlin in 1981. Many of the original scientific participants from the 1981 conference are also contributors to this new volume and, in conjunction with other expert biologists and philosophers specializing on these topics, provide an authoritative, comprehensive view on the subject. Taken together, the papers supply novel perspectives on how and why the conceptual landscape has shifted and stabilized in particular ways, yielding insights into the dynamic epistemic changes that have occurred over the past three decades. This volume will appeal to philosophers of biology studying conceptual change, evolutionary developmental biologists focused on comprehending the genesis of their field and evaluating its future directions, and historians of biology examining this period when the intersection of evolution and development rose again to prominence in biological science.

Genesis: The Evolution of Biology presents a history of the past two centuries of biology, suitable for use in courses, but of interest more broadly to evolutionary biologists, geneticists, and biomedical scientists, as well as general readers interested in the history of science. The book covers the early evolutionary biologists-Lamarck, Cuvier, Darwin and Wallace through Mayr and the neodarwinian synthesis, in much the same way as other histories of evolution have done, bringing in also (...) the social implications, the struggles with our religious understanding, and the interweaving of genetics into evolutionary theory. What is novel about Sapp's account is a real integration of the cytological tradition, from Schwann, Boveri, and the other early cell biologists and embryologists, and the coverage of symbiosis, microbial evolutionary phylogenies, and the new understanding of the diversification of life coming from comparative analyses of complete microbial genomes. The book is a history of theories about evolution, genes and organisms from Lamarck and Darwin to the present day. This is the first book on the general history of evolutionary biology to include the history of research and theories about symbiosis in evolution, and first to include research on microbial evolution which were excluded from the classical neo-Darwinian synthesis. Bacterial evolution, and symbiosis in evolution are also excluded from virtually every book on the history of biology. (shrink)
This book aims to "develop the idea that evolution is an axiomatic consequence of organismic information and cohesion systems obeying the second law of thermodynamics in a manner analogous to, but not identical with, the second law's usual application in physical and chemical systems." The authors "adhere to a particular methodological approach called phylogenetic systematics." They have "devoted most of their primary research efforts to discovering historical effects in developmental patterns." Finding that "such historical effects seem ubiquitous," they "began (...) to believe that these historical effects were constraints on the evolutionary process, suggesting the influence of a natural law of history.".

Evolutionary developmental biology (Evo-Devo) is a new and rapidly developing field of biology which focuses on questions in the intersection of evolution and development and has been seen by many as a potential synthesis of these two fields. This synthesis is the topic of the books reviewed here. Integrating Evolution and Development (edited by Roger Sansom and Robert Brandon), is a collection of papers on conceptual issues in Evo-Devo, while From Embryology to Evo-Devo (edited by Manfred (...) Laubichler and Jane Maienschein) is a history of the problem of the relations between ontogeny and phylogeny. (shrink)
Previous discussions of the evolution of the self have diverged greatly in their estimates of the date at which the capacity for self-thought emerged, the factors that led self-reflection to evolve, and the nature of the evidence offered to support these disparate conclusions. Beginning with the assumption that human self-awareness involves a set of distinct cognitive abilities that evolved at different times to solve different adaptive problems, we trace the evolution of self-awareness from the common ancestor of humans (...) and apes to the beginnings of culture, drawing upon paleontological, anthropological, biological, and psychological evidence. These data converge to suggest that that modern self-thought appeared just prior to the Middle-Upper Paleolithic transition, approximately 60,000 years ago.Recto running head: Evolution of the Self.

This paper examines the efforts in evolution research to understand form’s structure that developed in Italy during the first half of the twentieth century. In particular, it analyzes how the organic approach in biology and the study of organic form merged in the morphological research agendas of Giuseppe Colosi and Giuseppe Levi. These biologists sought to understand form’s inner composition and structure. First, I will briefly outline the morphological practices and frameworks used to study form changes and structures (...) in the early twentieth century. Second, I will discuss what the Italian biologist Antonio Pensa called the morphological problem. Third, I will examine Colosi’s response to the morphological problem. Fourth, I will analyze Levi’s morphological research program. As a result, this paper paves the way for a more nuanced and varied picture of the so-called “organicism movement” in the first half of the twentieth century by calling attention to morphology as practiced in Italian-speaking biology. In fact, alongside dialectical materialism and holistic biology, two of the main strands within organicism, the architectural approach to evolution as practiced in Italy and elsewhere had a profound impact on twentieth- and twenty-first-century organicism specifically and on evolutionary biology generally.

In this article, I am concerned with the public engagements of Julian Huxley, Lancelot Hogben, and J. B. S. Haldane. I analyze how they used the new insights into the genetics of heredity to argue against any biological foundations for antidemocratic ideologies, be it Nazism, Stalinism, or the British laissez-faire and class system. The most striking fact—considering the abuse of biological knowledge they contested—is that these biologists presented genetics itself as inherently democratic. Arguing from genetics, they developed an understanding of (...) diversity that cuts across divisions of race, class, or gender. Human diversity rightly understood was advantageous for societal progress. Huxley, Hogben, and Haldane did not hold identical political ideals, but they all argued for democratic reforms and increased planning geared toward greater social equality, and they did so under the label of scientific humanism. Huxley took issue with the notion that evolutionary history does not carry any moral lessons for human societies. Rather than being its antithesis, evolution was the basis of human sociality. In fact, the entire future progress of individuals and communities toward a democratic world order needed to be founded on the cosmic principles of evolution—a process that had to be guided by the biological expert with a strong sense of social responsibility.

The comparison between biological and social macroevolution is a very important (though insufficiently studied) subject whose analysis renders new significant possibilities to comprehend the processes, trends, mechanisms, and peculiarities of each of the two types of macroevolution. Of course, there are a few rather important (and very understandable) differences between them; however, it appears possible to identify a number of fundamental similarities. One may single out at least three fundamental sets of factors determining those similarities. First of all, those similarities (...) stem from the fact that in both cases we are dealing with very complex non-equilibrium (but rather stable) systems whose principles of functioning and evolution are described by the General Systems' Theory, as well as by a number of cybernetic principles and laws. -/- Secondly, in both cases we do not deal with isolated systems; in both cases we deal with a complex interaction between systems of organic systems and external environment, whereas the reaction of systems to external challenges can be described in terms of certain general principles (that, however, express themselves rather differently within the biological reality, on the one hand, and within the social reality, on the other). -/- Thirdly, it is necessary to mention a direct ‘genetic’ link between the two types of macroevolution and their mutual influence. -/- It is important to emphasize that the very similarity of the principles and regularities of the two types of macroevolution does not imply their identity. Rather significant similarities are frequently accompanied by enormous differences. For example, genomes of the chimpanzees and the humans are very similar – with differences constituting just a few per cent; however, there are enormous differences with respect to intellectual and social differences of the chimpanzees and the humans hidden behind the apparently ‘insignificant’ difference between the two genomes. Thus, in certain respects it appears reasonable to consider the biological and social macroevolution as a single macroevolutionary process. This implies the necessity to comprehend the general laws and regularities that describe this process, though their manifestations may display significant variations depending on properties of a concrete evolving entity (biological, or social one). An important notion that may contribute to the improvement of the operationalization level as regards the comparison between the two types of macroevolution is the one that we suggested some time ago – the social aromorphosis (that was developed as a counterpart to the notion of biological aromorphosis well established within Russian evolutionary biology). We regard social aromorphosis as a rare qualitative macrochange that increases in a very significant way complexity, adaptability, and mutual influence of the social systems, that opens new possibilities for social macrodevelopment. In our paper we discuss a number of regularities that describe biological and social macroevolution and that employ the notions of social and biological aromorphosis such as ones of the module evolution (or the evolutionary ‘block assemblage’), ‘payment for arogenic progress’ etc. (shrink)
Discusses the influence of Charles Darwin's theory of evolution on the field of science as well as its cultural influences, and challenges the origins and methods of Darwin's research.
In the years of the post-Darwinian debate, many American naturalists invoked the name of Lamarck to signal their belief in a purposive and anti-Darwinian view of evolution. Yet Weismann’s theory of germ-plasm continuity undermined the shared tenet of the neo-Lamarckian theories as well as the idea of the interchangeability between biological and social heredity. Edward Drinker Cope, the leader of the so-called “American School,” defended his neo-Lamarckian philosophy against every attempt to redefine the relationship between behavior, development, and heredity (...) beyond the epigenetic model of inheritance. This paper explores Cope’s late-career defense of neo-Lamarckism. Particular attention is dedicated to the debate he had with James Mark Baldwin before the publication of Baldwin’s own “A New Factor in Evolution”. I argue that Cope’s criticism was partly due to the fact that Baldwin’s theory of social heredity threatened Cope’s biologistic stance, as well as his attempt to preserve design in nature. This theoretical attitude had a remarkable impact on Baldwin’s arguments for the theory of organic selection. (shrink)
The debate about the levels of selection has been one of the most controversial both in evolutionary biology and in philosophy of science. Okasha’s book makes the sort of contribution that simply will not be able to be ignored by anyone interested in this field for many years to come. However, my interest here is in highlighting some examples of how Okasha goes about discussing his material to suggest that his book is part of an increasingly interesting trend that (...) sees scientists and philosophers coming together to build a broadened concept of “theory” through a combination of standard mathematical treatments and conceptual analyses. Given the often contentious history of the relationship between philosophy and science, such trend cannot but be welcome. (shrink)
This remarkable book presents a rich and up-to-date view of evolution that explores the far-reaching implications of Darwin's theory and emphasizes the power, significance, and relevance of evolution to our lives today. After all, we ourselves are the product of evolution, and we can tackle many of our gravest challenges -- from lethal resurgence of antiobiotic-resistant diseases to the wave of extinctions that looms before us -- with a sound understanding of the science.
Work throughout the history and philosophy of biology frequently employs ‘chance’, ‘unpredictability’, ‘probability’, and many similar terms. One common way of understanding how these concepts were introduced in evolution focuses on two central issues: the first use of statistical methods in evolution (Galton), and the first use of the concept of “objective chance” in evolution (Wright). I argue that while this approach has merit, it fails to fully capture interesting philosophical reflections on the role of (...) chance expounded by two of Galton's students, Karl Pearson and W.F.R. Weldon. Considering a question more familiar from contemporary philosophy of biology—the relationship between our statistical theories of evolution and the processes in the world those theories describe—is, I claim, a more fruitful way to approach both these two historical actors and the broader development of chance in evolution.

The Discovery of Evolution explains what the theory of evolution is all about by providing a historical narrative of discovery. Some of the major puzzles that confront anyone studying living things are discussed and it details how these were solved from an evolutionary perspective. Beginning with the emergence of the early naturalists in the seventeenth century, the scientific discoveries that led up to and then flowed from Darwin and Wallace's theory of evolution by natural selection are then (...) discussed, and finally the modern evolutionary studies at the close of the twentieth century are detailed. This new edition of The Discovery of Evolution is fully updated and contains a new chapter on the evolutionary studies of the twentieth century. By approaching the topic of evolution in this way, it is made accessible to the non-specialist and no previous study of biology is required in order to read and understand this book. (shrink)
It has long been claimed that Homo sapiens is the only species that has language, but only recently has it been recognized that humans also have an unusual pattern of growth and development. Social mammals have two stages of pre-adult development: infancy and juvenility. Humans have two additional prolonged and pronounced life history stages: childhood, an interval of four years extending between infancy and the juvenile period that follows, and adolescence, a stage of about eight years that stretches from (...) juvenility to adulthood. We begin by reviewing the primary biological and linguistic changes occurring in each of the four pre-adult ontogenetic stages in human life history. Then we attempt to trace the evolution of childhood and juvenility in our hominin ancestors. We propose that several different forms of selection applied in infancy and childhood; and that, in adolescence, elaborated vocal behaviors played a role in courtship and intrasexual competition, enhancing fitness and ultimately integrating performative and pragmatic skills with linguistic knowledge in a broad faculty of language. A theoretical consequence of our proposal is that fossil evidence of the uniquely human stages may be used, with other findings, to date the emergence of language. If important aspects of language cannot appear until sexual maturity, as we propose, then a second consequence is that the development of language requires the whole of modern human ontogeny. Our life history model thus offers new ways of investigating, and thinking about, the evolution, development, and ultimately the nature of human language. (shrink)
Biological evolution and technological innovation, while differing in many respects, also share common features. In particular, implementation of a new technology in the market is analogous to the spreading of a new genetic trait in a population. Technological innovation may occur either through the accumulation of quantitative changes, as in the development of the ocean clipper, or it may be initiated by a new combination of features or subsystems, as in the case of steamships. Other examples of the latter (...) type are electric networks that combine the generation, distribution, and use of electricity, and containerized transportation that combines standardized containers, logistics, and ships. Biological evolution proceeds, phenotypically, in many small steps, but at the genetic level novel features may arise not only through the accumulation of many small, common mutational changes, but also when distinct, relatively rare genetic changes are followed by many further mutations. In particular, capabilities of biologically modern man may have been initiated, perhaps some 150 000 years ago, by one or few accidental but distinct combinations of modules and subroutines of gene regulation which are involved in the generation of the neural network in the cerebral cortex. It is even conceivable that it was one primary genetic event that initiated the evolution of biologically modern man, introducing some novel but subtle feature of connectivity into the cerebral cortex which allowed for meta-levels of abstraction and upgraded modes of information processing. This may have set the stage for the evolution of integrated but diverse higher capabilities such as structured language, symbolic thought, strategic thought, and cognition based empathy. (shrink)
This paper traces the historical origins of Friedrich A. Hayek's theory of cultural evolution, and argues that Hayek's evolutionary thought was significantly inspired by Alexander M. Carr-Saunders and Oxford zoology. While traditional Hayek scholarship emphasizes the influence of Carl Menger and the British eighteenth-century moral philosophers, I claim that these sources underdetermine what was most characteristic of Hayek's theory, viz. the idea that cultural evolution is a matter of group selection, and the idea that natural selection operates on (...) acquired as well as on inherited properties.

This book is focused on the conceptual structure of the theory of evolution, and will be of value primarily for theoretical biologists and philosophers of biology who are interested in the question of the explanatory character of evolutionary theory.

This feature makes the book an excellent resource for (...) the identification of the most recent authors and disputes among evolutionists. (shrink)
The renowned biologist and thinker Richard Dawkins presents his most expansive work yet: a comprehensive look at evolution, ranging from the latest developments in the field to his own provocative views. Loosely based on the form of Chaucer's Canterbury Tales, Dawkins's Tale takes us modern humans back through four billion years of life on our planet. As the pilgrimage progresses, we join with other organisms at the forty "rendezvous points" where we find a common ancestor. The band of pilgrims (...) swells into a vast crowd as we join first with other primates, then with other mammals, and so on back to the first primordial organism. Dawkins's brilliant, inventive approach allows us to view the connections between ourselves and all other life in a bracingly novel way. It also lets him shed bright new light on the most compelling aspects of evolutionary history and theory: sexual selection, speciation, convergent evolution, extinction, genetics, plate tectonics, geographical dispersal, and more. The Ancestor's Tale is at once a far-reaching survey of the latest, best thinking on biology and a fascinating history of life on Earth. Here Dawkins shows us how remarkable we are, how astonishing our history, and how intimate our relationship with the rest of the living world. (shrink)
