How does cooperation emerge among selfish individuals? When do people share resources, punish those they consider unfair, and engage in joint enterprises? These questions fascinate philosophers, ...biologists, and economists alike, for the "invisible hand" that should turn selfish efforts into public benefit is not always at work. The Calculus of Selfishness looks at social dilemmas where cooperative motivations are subverted and self-interest becomes self-defeating. Karl Sigmund, a pioneer in evolutionary game theory, uses simple and well-known game theory models to examine the foundations of collective action and the effects of reciprocity and reputation.
In 1809--the year of Charles Darwin's birth--Jean-Baptiste Lamarck published Philosophie zoologique, the first comprehensive and systematic theory of biological evolution. The Lamarckian approach ...emphasizes the generation of developmental variations; Darwinism stresses selection. Lamarck's ideas were eventually eclipsed by Darwinian concepts, especially after the emergence of the Modern Synthesis in the twentieth century. The different approaches--which can be seen as complementary rather than mutually exclusive--have important implications for the kinds of questions biologists ask and for the type of research they conduct. Lamarckism has been evolving--or, in Lamarckian terminology, transforming--since Philosophie zoologique's description of biological processes mediated by "subtle fluids." Essays in this book focus on new developments in biology that make Lamarck's ideas relevant not only to modern empirical and theoretical research but also to problems in the philosophy of biology. Contributors discuss the historical transformations of Lamarckism from the 1820s to the 1940s, and the different understandings of Lamarck and Lamarckism; the Modern Synthesis and its emphasis on Mendelian genetics; theoretical and experimental research on such "Lamarckian" topics as plasticity, soft (epigenetic) inheritance, and individuality; and the importance of a developmental approach to evolution in the philosophy of biology. The book shows the advantages of a "Lamarckian" perspective on evolution. Indeed, the development-oriented approach it presents is becoming central to current evolutionary studies--as can be seen in the burgeoning field of Evo-Devo. Transformations of Lamarckism makes a unique contribution to this research.
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, first published in 2004, 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.
This book explains the history and strategy of the intelligent design creationist movement, which is headquartered at the Discovery Institute’s Center for Science and Culture in Seattle, WA. The ...movement’s twenty-year “Wedge Strategy,” implementation of which began in 1998, is aimed at bringing intelligent design into American public schools, public policymaking, and the cultural mainstream. Beginning with a brief history of the movement and the authentication of the “Wedge Document,” in which the Wedge Strategy is outlined, the book critiques the incompetent science and rhetorical tactics of the movement’s leaders: Douglas Axe, Paul Chien, Jonathan Wells, Michael Behe, and William Dembski. The movement’s own documents reveal its religious funding sources and its execution of all phases of the strategy except the production of genuine scientific data, including its development of a legal defense against challenges to the teaching of intelligent design. The book recounts the movement’s political maneuvering in its effort to influence science curricula in individual states, most notably Kansas and Ohio, and to develop political support among members of Congress. Importantly, the book documents the centrality of religion to intelligent design, its leaders’ associations with Christian extremists, its continuity with earlier forms of creationism, and its ambitions for academic legitimacy. This 2007 edition provides updates on the movement’s efforts in Kansas and Ohio and offers a firsthand account by Barbara Forrest, who was an expert witness for the plaintiffs, of the landmark legal case involving intelligent design, Kitzmiller et al. v. Dover Area School District (2005).
Lake Malazi cichlids have evolved rapidly, extensively, and in some cases iteratively to fill an array of ecological niches; however, neither species richness nor trophic diversity is distributed ...equally across lineages. In the context of evolutionary theory, such differences offer predictions about the magnitudes and patterns of morphological variation within lineages. In this paper, we use geometric morphometrics in three prevalent rock-dwelling genera to address questions related to morphological diversity, disparity, integration, and modularity. In particular, we focus on comparisons between the highly specialized and species-poor genus, Labeotropheus (Ahl in Sitzungsberichte der Berlinische Gesellschaft Naturforschender Freunde zu Berlin 1926:51-62, 1927 (See CR2)), and the more ecologically diverse and species-rich genus, Tropheops (Trewavas in Revue Française d'Aquariologie Herpétologie 10:97-106, 1984 (See CR50)), as well as between species with lake-wide versus more limited distributions. We find that Labeotropheus exhibits comparable levels of morphological disparity to Tropheops, which suggests that a specialized foraging mode has not constrained cranial variability in this genus. We also find that species with a lake-wide distribution exhibit levels of disparity three times greater than that in a species with a limited distribution. Finally, we show that magnitudes of integration and patterns of modularity are lineage specific, and do not directly correspond to ecology. In sum, these data provide insights into the complex relationship between ecology, morphological variability, and evolvability.
Quantitative approaches to evolutionary biology traditionally consider evolutionary change in isolation from an important pressure in natural selection: the demography of coevolving populations. In ...Analysis of Evolutionary Processes, Fabio Dercole and Sergio Rinaldi have written the first comprehensive book on Adaptive Dynamics (AD), a quantitative modeling approach that explicitly links evolutionary changes to demographic ones. The book shows how the so-called AD canonical equation can answer questions of paramount interest in biology, engineering, and the social sciences, especially economics. After introducing the basics of evolutionary processes and classifying available modeling approaches, Dercole and Rinaldi give a detailed presentation of the derivation of the AD canonical equation, an ordinary differential equation that focuses on evolutionary processes driven by rare and small innovations. The authors then look at important features of evolutionary dynamics as viewed through the lens of AD. They present their discovery of the first chaotic evolutionary attractor, which calls into question the common view that coevolution produces exquisitely harmonious adaptations between species. And, opening up potential new lines of research by providing the first application of AD to economics, they show how AD can explain the emergence of technological variety.
Marking Time, edited by Joel Faflak, analyses prevailing notions of evolution by tracing its origins to the literary, scientific, and philosophical discourses of the long nineteenth century.

Evolution: a process we've all been through but have yet to fully understand. You started off as a tiny little creature who couldn't talk, couldn't walk, and didn't even have feet. There were many ...other possibilities, too, but, somehow, nature decided you were the fittest. You were given the chance to live and do your thing in the world, while millions of others were discarded at the concept stage. Genes from your parents were selected, combined, and modified in an attempt to make you best adapted to your environment. This whole process is fascinating: how does nature decide what features give you the chance to be the best that you can be?
