proposes an approach to evolution that is more in harmony with modern science than Darwinism or neo-Darwinism

"The author begins by defining phenotypic plasticity and detailing its history, including important experiments and methods of statistical and graphical analysis. He then provides extended examples and discussion of the molecular basis of plasticity, the plasticity of development, the ecology of plastic responses, and the role of costs and constraints in the evolution of plasticity. A brief epilogue looks at how plasticity studies shed light on the nature/nurture debate in the popular media.".

Anthony O'Hear takes a stand against the fashion for explaining human behaviour in terms of evolution. He maintains, controversially, that while the theory of evolution is successful in explaining the development of the natural world in general, it is of limited value when applied to the human world. Because of our reflectiveness and our rationality we take on goals and ideals which cannot be justified in terms of survival-promotion or reproductive advantage. O'Hear examines the nature of human self-consciousness, and argues that evolutionary theory cannot give a satisfactory account of such distinctive facets of human life as the quest for knowledge, moral sense, and the appreciation of beauty; in these we transcend our biological origins. It is our rationality that allows each of us to go beyond not only our biological but also our cultural inheritance: as the author says in the Preface, 'we are prisoners neither of our genes nor of the ideas we encounter as we each make our personal and individual way through life'.

In Ryan's view, cooperation, not competition, lies at the heart of human society.".

Alfred Russel Wallace (1823 - 1913) was one of the late nineteenth century's most potent intellectual forces. His link to Darwin as co-discoverer of the principle of natural selection alone would have secured him a place in history, but he went on to complete work entitling him to recognition as the 'father' of modern biogeographical studies, as a pioneer in the field of astrobiology, and as an important contributor to subjects as far-ranging as glaciology, land reform, anthropology and ethnography, and epidemiology. Beyond this, many are coming to regard Wallace as the pre-eminent field biologist, collector, and naturalist of tropical regions. Add to that the fact that he was a vocal supporter of spiritualism, socialism, and the rights of the ordinary person, and it quickly becomes apparent that Wallace was a man of extraordinary breadth of attention. Yet his work in many of these areas is still not well known, and still less recognized is his relevance to current day research almost 100 years after his death. This rich collection of writings by more than twenty historians and scientists reviews and reflects on the work that made Wallace a famous man in his own time, and a figure of extraordinary influence and continuing interest today.
