George C. Williams (1926–2010)

Williams, in what is now considered a classic by evolutionary biologists, [1] outlines a gene-centered view of evolution , [2] disputes notions of evolutionary progress , and criticizes contemporary models of group selection , including the theories of Alfred Emerson , A. Sturtevant , and to a smaller extent, the work of V. The aim of the book is to "clarify certain issues in the study of adaptation and the underlying evolutionary processes. It was mostly written in the summer of when Williams utilized the University of California, Berkeley 's library. Williams argues that adaptation is "a special and onerous concept that should not be used unnecessarily". For instance he considers mutations to be errors only, not a process that has persisted to provide variation and evolutionary potential. If something is considered after critical appraisal to be an adaptation, then we should assume the unit of selection in the process was as simple as possible, provided it is compatible with the evidence.

Adaptation and Natural Selection: A Critique of Some Current Evolutionary Thought

Patterns and Processes in the History of Life pp Cite as. Biologists often use abstractions developed in one context to describe material mechanisms observed in another, where the connection is not as certain. For traits varying at all levels, selection within populations must dominate. For traits fixed within but varying among clades, only selection at higher levels can have any impact. Here selection will be slow but can produce major change.

Biological evolution is a fact--but the many conflicting theories of evolution remain controversial even today. In , simple Darwinism, which holds that evolution functions primarily at the level of the individual organism, was threatened by opposing concepts such as group selection, a popular idea stating that evolution acts to select entire species rather than individuals. George Williams's famous argument in favor of the Darwinists struck a powerful blow to those in opposing camps. His Adaptation and Natural Selection, now a classic of science literature, is a thorough and convincing essay in defense of Darwinism; its suggestions for developing effective principles for dealing with the evolution debate and its relevance to many fields outside biology ensure the timelessness of this critical work. A beautifully written and excellently reasoned essay in defense of Darwinian selection as a sufficient theory to explain evolution without the necessity of group selection, population adaptation, or progress. Adaptation and Natural Selection.

Biological evolution is a fact—but the many conflicting theories of evolution remain controversial even today. When Adaptation and Natural Selection was first published in , it struck a powerful blow against those who argued for the concept of group selection—the idea that evolution acts to select entire species rather than individuals. Now with a new foreword by Richard Dawkins, Adaptation and Natural Selection is an essential text for understanding the nature of scientific debate. On the whole it will have a very beneficial influence on biology with a rich supply of subjects and targets for some years to come…. This is a carefully constructed, carefully written scholarly work, in the best sense of these words. Adaptation and Natural Selection.

Williams and John Maynard Smith arrived at slightly different conclusions about the evolutionary maintenance of sexual reproduction, despite that both were staunch neo-Darwinians, simply because they approached the problem from different angles life history vs. This difference between their perspectives made them notice the so-called paradox of sexual reproduction for the first time. Evidence from before, during and after the recognition of the paradox supports this thesis of constructive difference. First, Maynard Smith had diagnosed the individual cost of sexual reproduction in full detail by , but nobody raised an eyebrow for a decade.
