Much of the evolutionary debate since Darwin has focused on the level at which natural selection occurs. Most biologists acknowledge multiple levels of selection—from the gene to the species. The debate about group selection, however, is the focus of Mark E. Borrello’s Evolutionary Restraints. Tracing the history of biological attempts to determine whether selection leads to the evolution of fitter groups, Borrello takes as his focus the British naturalist V. C. Wynne-Edwards, who proposed that animals could regulate their own populations and thus avoid overexploitation of their resources. By the mid-twentieth century, Wynne-Edwards became an advocate for group selection theory and led a debate that engaged the most significant evolutionary biologists of his time, including Ernst Mayr, G. C. Williams, and Richard Dawkins. This important dialogue bled out into broader conversations about population regulation, environmental crises, and the evolution of human social behavior. By examining a single facet in the long debate about evolution, Borrello provides powerful insight into an intellectual quandary that remains relevant and alive to this day.

Living things are constantly engaged in a struggle for existence, and ingenious devices for the purpose of self-preservation can be seen in all types of animal and plant life. However, nature also displays phenomena that are not related to survival or that seem clearly to violate the principle of self-preservation - particularly when organisms interact with one another. Darwin investigated these apparent contradictions and proposed that both mechanisms of self preservation and those of reproduction are explained by a more basic principle of "natural selection" - the reproductive survival of the fittest. George C. Williams in "Group Selection" challenges the adequacy of this process of selection at the individual level.Williams has here collected the work of the chief partisans with opposed viewpoints on the theory of selection at the group level to state their arguments and rebuttals. A minority of modern biologists offer evidence to show that groups of living things are organized to assure their collective survival; they are not merely collections of individuals designed for their own survival and reproduction. In opposition, defenders of the traditional point of view charge that mechanisms of group survival are based on illusion and misinterpretation.Because of the wide range of opinion expressed in "Group Selection", the reader is exposed to all sides of the dispute and encouraged to form his or her own views. In addition, as a source book on current evolutionary issues or for research or reference material, "Group Selection" remains a valuable addition to every personal and institutional library in the biological sciences.

One of the nation's leading neuroscientists presents a radically new view of the function of the brain and the nervous system. Its central idea is that the nervous system in each individual operates as a selective system resembling natural selection in evolution, but operating by different mechanisms. This far-ranging theory of brain functions is bound to stimulate renewed discussion of such philosophical issues as the mind-body problem, the origins of knowledge and the perceptual bases of language. Notes and Index.

Many animals regulate their population density by patterns of behavior that would be easy to explain if the forces of natural selection acted to optimize group properties. But Darwinian selection acts on individuals, not groups, and most simple theories have shown group selection to be too slow ever to oppose individual selection successfully. In this book Michael Gilpin presents a model, based on predator-prey dynamics, wherein nonlinear effects are important, so that small advantages to the selfish individual are nonlinearly amplified into disaster for his group. The result is that group selection can be rapid and powerful. Of course many instances of apparent group selection can be explained by kin selection; in other cases, close examination reveals that seemingly altruistic behavior directly benefits the individual genotype as well as the group. The value of the monograph is that it provides a robust model in which group selection, pure and unadulterated, can be seen to work.

Science need not be dull and bogged down by jargon, as Richard Dawkins proves in this entertaining look at evolution. The themes he takes up are the concepts of altruistic and selfish behaviour; the genetical definition of selfish interest; the evolution of aggressive behaviour; kinshiptheory; sex ratio theory; reciprocal altruism; deceit; and the natural selection of sex differences.

Leading scholars report on current research that demonstrates the central role of cultural evolution in explaining human behavior. Over the past few decades, a growing body of research has emerged from a variety of disciplines to highlight the importance of cultural evolution in understanding human behavior. Wider application of these insights, however, has been hampered by traditional disciplinary boundaries. To remedy this, in this volume leading researchers from theoretical biology, developmental and cognitive psychology, linguistics, anthropology, sociology, religious studies, history, and economics come together to explore the central role of cultural evolution in different aspects of human endeavor. The contributors take as their guiding principle the idea that cultural evolution can provide an important integrating function across the various disciplines of the human sciences, as organic evolution does for biology. The benefits of adopting a cultural evolutionary perspective are demonstrated by contributions on social systems, technology, language, and religion. Topics covered include enforcement of norms in human groups, the neuroscience of technology, language diversity, and prosociality and religion. The contributors evaluate current research on cultural evolution and consider its broader theoretical and practical implications, synthesizing past and ongoing work and sketching a roadmap for future cross-disciplinary efforts.

Cooperation among humans is one of the keys to our great evolutionary success. Natalie and Joseph Henrich examine this phenomena with a unique fusion of theoretical work on the evolution of cooperation, ethnographic descriptions of social behavior, and a range of other experimental results. Their experimental and ethnographic data come from a small, insular group of middle-class Iraqi Christians called Chaldeans, living in metro Detroit, whom the Henrichs use as an example to show how kinship relations, ethnicity, and culturally transmitted traditions provide the key to explaining the evolution of cooperation over multiple generations.
