Charles Darwin's "On the Origins of Species" had two principal goals: to show that species had not been separately created and to show that natural selection had been the main force behind their proliferation and descent from common ancestors. In "Coevolution," the author proposes a powerful new theory of cultural evolution--that is, of the descent with modification of the shared conceptual systems we call "cultures"--that is parallel in many ways to Darwin's theory of organic evolution. The author suggests that a process of cultural selection, or preservation by preference, driven chiefly by choice or imposition depending on the circumstances, has been the main but not exclusive force of cultural change. He shows that this process gives rise to five major patterns or "modes" in which cultural change is at odds with genetic change. Each of the five modes is discussed in some detail and its existence confirmed through one or more case studies chosen for their heuristic value, the robustness of their data, and their broader implications. But "Coevolution" predicts not simply the existence of the five modes of gene-culture relations; it also predicts their relative importance in the ongoing dynamics of cultural change in particular cases. The case studies themselves are lucid and innovative reexaminations of an array of oft-pondered anthropological topics--plural marriage, sickle-cell anemia, basic color terms, adult lactose absorption, incest taboos, headhunting, and cannibalism. In a general case, the author's goal is to demonstrate that an evolutionary analysis of both genes and culture has much to contribute to our understanding of human diversity, particularly behavioral diversity, and thus to the resolution of age-old questions about nature and nurture, genes and culture.

The central concern of this book is with the "prediction problem" in biomedical research. In particular, the authors examine the use of animal models to predict human responses in drug and disease research. The arguments discussed are drawn from both biological and biomedical theory (with numerous examples and case studies drawn from evolutionary biology, complex systems theory, oncology, teratology, and AIDS research), and analyses of empirical evidence (concerning, for example, data on intra- and inter-species differences revealed by recent results from genome analyses of various species, human population studies, and statistical studies of the predictive utility of animal models). This book comes to the unique conclusion that while animals can be successfully used for many endeavors in science such as basic and comparative research, they cannot be used to predict drug and disease response in humans. The arguments presented are rooted in the history, philosophy, and methodology of biomedical research. This book will be of interest to anyone involved, directly or indirectly, in biomedical research (including physicians, veterinarians and scientists), and anyone interested in the history, philosophy and methodology of science. In contrast to books written by and for the animal rights movement and books written by and for the animal-based research industry, this book honestly examines all sides of the scientific arguments for using animals in science and concludes that each group in turn exaggerates the flaws or strengths of using animals. There are areas in science where animals can be viably used but there are also areas where they cannot be so used. REVIEWS See Philosophies, Ethics, and Humanities in Medicine 17 August 2010

The public is now paying considerable attention to the use of molecular evidence in studies of human diversity and origins. Much of the early work in this area was based on evidence from mitochondrial DNA, but this has now been supplemented by important new information from nuclear DNA from both Y chromosomes and the autosomes. The bulk of the material available is from living populations, but this is being extended by the study of DNA from archaic populations. The underlying models used in interpreting this evidence are based on the neutral theory of molecular evolution, but also consider the possible role of selection. This volume brings together much new evidence and methodology from an international group of scientists.

In this innovative celebration of diversity and affirmation of individuality in animals and humans, Joan Roughgarden challenges accepted wisdom about gender identity and sexual orientation. A distinguished evolutionary biologist, Roughgarden takes on the medical establishment, the Bible, social science—and even Darwin himself. She leads the reader through a fascinating discussion of diversity in gender and sexuality among fish, reptiles, amphibians, birds, and mammals, including primates. Evolution's Rainbow explains how this diversity develops from the action of genes and hormones and how people come to differ from each other in all aspects of body and behavior. Roughgarden reconstructs primary science in light of feminist, gay, and transgender criticism and redefines our understanding of sex, gender, and sexuality. Witty, playful, and daring, this book will revolutionize our understanding of sexuality. Roughgarden argues that principal elements of Darwinian sexual selection theory are false and suggests a new theory that emphasizes social inclusion and control of access to resources and mating opportunity. She disputes a range of scientific and medical concepts, including Wilson's genetic determinism of behavior, evolutionary psychology, the existence of a gay gene, the role of parenting in determining gender identity, and Dawkins's "selfish gene" as the driver of natural selection. She dares social science to respect the agency and rationality of diverse people; shows that many cultures across the world and throughout history accommodate people we label today as lesbian, gay, and transgendered; and calls on the Christian religion to acknowledge the Bible's many passages endorsing diversity in gender and sexuality. Evolution's Rainbow concludes with bold recommendations for improving education in biology, psychology, and medicine; for democratizing genetic engineering and medical practice; and for building a public monument to affirm diversity as one of our nation's defining principles.

Virtually all aspects of human behavior show enormous variation both within and between cultural groups, including material culture, social organization and language. Thousands of distinct cultural groups exist: about 6,000 languages are spoken today, and it is thought that a far greater number of languages existed in the past but became extinct. Using a Darwinian approach, this book seeks to explain this rich cultural variation. There are a number of theoretical reasons to believe that cultural diversification might be tree-like, that is phylogenetic: material and non-material culture is clearly inherited by descendants, there is descent with modification, and languages appear to be hierarchically related. There are also a number of theoretical reasons to believe that cultural evolution is not tree-like: cultural inheritance is not Mendelian and can indeed be vertical, horizontal or oblique, evidence of borrowing abounds, cultures are not necessarily biological populations and can be transient and complex. Here, for the first time, this title tackles these questions of cultural evolution empirically and quantitatively, using a range of case studies from Africa, the Pacific, Europe, Asia and America. A range of powerful theoretical tools developed in evolutionary biology is used to test detailed hypotheses about historical patterns and adaptive functions in cultural evolution. Evidence is amassed from archaeological, linguist and cultural datasets, from both recent and historical or pre-historical time periods. A unifying theme is that the phylogenetic approach is a useful and powerful framework, both for describing the evolutionary history of these traits, and also for testing adaptive hypotheses about their evolution and co-evolution. Contributors include archaeologists, anthropologists, evolutionary biologists and linguists, and this book will be of great interest to all those involved in these areas.
