A new theory of the evolution of human cognition and human social life that emphasizes the role of information sharing across generations. Over the last three million years or so, our lineage has diverged sharply from those of our great ape relatives. Change has been rapid (in evolutionary terms) and pervasive. Morphology, life history, social life, sexual behavior, and foraging patterns have all shifted sharply away from those of the other great apes. In The Evolved Apprentice, Kim Sterelny argues that the divergence stems from the fact that humans gradually came to enrich the learning environment of the next generation. Humans came to cooperate in sharing information, and to cooperate ecologically and reproductively as well, and these changes initiated positive feedback loops that drove us further from other great apes. Sterelny develops a new theory of the evolution of human cognition and human social life that emphasizes the gradual evolution of information-sharing practices across generations and how these practices transformed human minds and social lives. Sterelny proposes that humans developed a new form of ecological interaction with their environment, cooperative foraging. The ability to cope with the immense variety of human ancestral environments and social forms, he argues, depended not just on adapted minds but also on adapted developmental environments.

A novel account of the evolution of language and the cognitive capacities on which language depends. In From Signal to Symbol, Ronald Planer and Kim Sterelny propose a novel theory of language: that modern language is the product of a long series of increasingly rich protolanguages evolving over the last two million years. Arguing that language and cognition coevolved, they give a central role to archaeological evidence and attempt to infer cognitive capacities on the basis of that evidence, which they link in turn to communicative capacities. Countering other accounts, which move directly from archaeological traces to language, Planer and Sterelny show that rudimentary forms of many of the elements on which language depends can be found in the great apes and were part of the equipment of the earliest species in our lineage. After outlining the constraints a theory of the evolution of language should satisfy and filling in the details of their model, they take up the evolution of words, composite utterances, and hierarchical structure. They consider the transition from a predominantly gestural to a predominantly vocal form of language and discuss the economic and social factors that led to language. Finally, they evaluate their theory in terms of the constraints previously laid out.

This volume addresses key questions about the puzzle of human origins by focusing on a topic that is largely unexplored thus far, namely, the evolution of human wisdom. How can we best understand the human capacity for wisdom, where did it come from, and how did it emerge? It explores lines of convergence and divergence between Christian theology and evolutionary anthropology in its search to identify different aspects of wisdom. Critical to this discussion are the philosophical difficulties that arise when two very different methodological approaches to the manner of humans becoming wise are brought together. The relative importance and significance of human language is another area of intense debate in defining the meaning of wisdom and its expression. How far and to what extent does a theologically informed wisdom discourse push evolutionary anthropology to formulate new questions and vice versa? This volume shows that there is no simple consonance between evolutionary anthropology and theology. Yet, each discipline has much to learn from the other; the authors are in agreement that even in the midst of an awareness of dissonance and some tension, there can still be mutual respect. The goal of this book is to begin to develop a trans-disciplinary approach to the evolution of human wisdom, where each discipline is challenged to ask questions in a new way. This volume tackles the relationship between theology and science in a fresh way by focusing on a specific theme—wisdom—that is equally generative for both theology and evolutionary anthropology.

“An ambitious and exciting book about creativity . . . chart[s] new territory.” —Science Consider Miles Davis, horn held high, sculpting a powerful musical statement full of tonal patterns, inside jokes, and thrilling climactic phrases—all on the fly. Or a comedy troupe riffing on cues from the audience until the whole room erupts with laughter; a team of software engineers brainstorming their way to the next Google; or the Einsteins of the world code-cracking the mysteries of nature. Maybe it’s simply a child playing with her toys. What do all of these activities share? With wisdom, humor, and joy, philosopher Stephen T. Asma answers that question: imagination. And from there he takes us on an extraordinary tour of the human creative spirit. Guided by neuroscience, animal behavior, evolution, philosophy, and psychology, Asma burrows deep into the human psyche to look at the enigmatic, powerful engine that is our improvisational creativity—the source, he argues, of our remarkable imaginational capacity. How, he asks, can a story evoke a whole world inside us? How are we able to rehearse a skill, a speech, or even an entire scenario simply by thinking about it? How does creativity go beyond experience and help us make something completely new? And how does our moral imagination help us sculpt a better society? As he shows, we live in a world that is only partly happening in reality. Huge swaths of our cognitive experiences are made up by “what-ifs,” “almosts,” and “maybes,” an imagined terrain that churns out one of the most overlooked but necessary resources for our flourishing: possibilities. Considering everything from how imagination works in our physical bodies to the ways we make images, from the mechanics of language and our ability to tell stories to the creative composition of self-consciousness, Asma expands our personal and day-to-day forms of imagination into a grand scale: as one of the decisive evolutionary forces that has guided human development from the Paleolithic era to today. The result is an inspiring look at the rich relationships among improvisation, imagination, and culture, and a privileged glimpse into the unique nature of our evolved minds.

In The Evolution of Moral Progress, Allen Buchanan and Russell Powell resurrect the project of explaining moral progress. They avoid the errors of earlier attempts by drawing on a wide range of disciplines including moral and political philosophy, evolutionary biology, evolutionary psychology, anthropology, history, and sociology. Their focus is on one especially important type of moral progress: gains in inclusivity. They develop a framework to explain progress in inclusivity to also illuminate moral regression--the return to exclusivist and "tribalistic" moral beliefs and attitudes. Buchanan and Powell argue those tribalistic moral responses are not hard-wired by evolution in human nature. Rather, human beings have an evolved "adaptively plastic" capacity for both inclusion and exclusion, depending on environmental conditions. Moral progress in the dimension of inclusivity is possible, but only to the extent that human beings can create environments conducive to extending moral standing to all human beings and even to some animals. Buchanan and Powell take biological evolution seriously, but with a critical eye, while simultaneously recognizing the crucial role of culture in creating environments in which moral progress can occur. The book avoids both biological and cultural determinism. Unlike earlier theories of moral progress, their theory provides a naturalistic account that is grounded in the best empirical work, and unlike earlier theories it does not present moral progress as inevitable or as occurring in definite stages; but rather it recognizes the highly contingent and fragile character of moral improvement.

"A supremely enjoyable, intoxicating work." —Nature How did we come to have minds? For centuries, poets, philosophers, psychologists, and physicists have wondered how the human mind developed its unrivaled abilities. Disciples of Darwin have explained how natural selection produced plants, but what about the human mind? In From Bacteria to Bach and Back, Daniel C. Dennett builds on recent discoveries from biology and computer science to show, step by step, how a comprehending mind could in fact have arisen from a mindless process of natural selection. A crucial shift occurred when humans developed the ability to share memes, or ways of doing things not based in genetic instinct. Competition among memes produced thinking tools powerful enough that our minds don’t just perceive and react, they create and comprehend. An agenda-setting book for a new generation of philosophers and scientists, From Bacteria to Bach and Back will delight and entertain all those curious about how the mind works.

From mitochondria to meerkats, the natural world is full of spectacular examples of social behaviour. In the early 1960s Bill Hamilton changed the way we think about how such behaviour evolves. He introduced three key innovations - now known as Hamilton's rule, kin selection, and inclusive fitness - which have been enormously influential, but which remain the subject of fierce controversy. Hamilton's pioneering work kick-started a research program now known as social evolution theory. This is a book about the philosophical foundations and future prospects of that program. Part I, "Foundations", is a careful exposition and defence of Hamilton's ideas, with a few modifications along the way. In Part II, "Extensions", Jonathan Birch shows how these ideas can be applied to phenomena including cooperation in micro-organisms, cooperation among the cells of a multicellular organism, and culturally evolved cooperation in the earliest human societies. Birch argues that real progress can be made in understanding microbial evolution, evolutionary transitions, and human evolution by viewing them through the lens of social evolution theory, provided the theory is interpreted with care and adapted where necessary. The Philosophy of Social Evolution places social evolution theory on a firm philosophical footing and sets out exciting new directions for further work.
