Evolutionary Processes and Metaphors

Book excerpt: Evolutionary Processes and Metaphors Edited by Mae-Wan Ho, Department of Biology, The Open University, UK Sidney W. Fox, Institute for Molecular and Cellular Evolution, University of Miami, USA The current evolutionary debate encompasses protobiotic chemistry at one extreme and human sociobiology at the other. Meanwhile, significant advances continue to be made in many scientific disciplines which have far-reaching implications on our view of nature. Although it is now generally felt that neo-Darwinism, at least in its orthodox form, is no longer an adequate theory of evolution, very few attempts have yet been made to articulate a coherent alternative out of the many voices of dissent. The purpose of the present volume is two-fold: to work towards a new evolutionary synthesis which takes full account of contemporary knowledge in all disciplines; and to examine explicitly the metaphorical basis of evolutionary theories old and new, as this has a powerful impact on our humanistic perspectives which underpin all social and political actions. We have brought together representatives of two groups of workers: those who ultimately believe in working within a transformed neo-Darwinism, and others who advocate a more radical reorientation away from the orthodoxy. Despite their fundamentally different affiliations, they are nonetheless able to communicate on questions of evolutionary concepts and mechanisms and their wider relevance to science and society. New insights are presented on major issues such as the physicochemical underpinnings of life processes, the meaning of natural selection, the nature of variation, heredity and morphogenesis, the integration of organism and environment, the active role of the organism in evolution and the evolution of human society. The new synthesis which is emerging is an integrated, multilevel and multidisciplinary approach to evolution which accords not only with the state of present-day knowledge, but with our deepest experience of nature.
