Evolution as Natural History: A Philosophical AnalysisWim van der Steen charts conceptual foundations of evolutionary biology and, on the basis of this, he evaluates applications of evolutionary theory outside biology. Philosophical analysis shows that key notions of the theory such as fitness, adaptation, selection, and optimality are empty place-holder concepts that call for context-dependent specifications of meaning. For example, as he points out, the notion of optimality is empty without a specification of constraints. Hence, the controversial thesis that animals perform optimal behaviors as a result of natural selection is meaningless rather than true or false. Analysis shows that many other controversies in evolutionary biology are spurious. Thus, the thesis of genic selectionism, which puts genes at center stage in evolutionary theory, is best reconstructed as an arbitrary conceptualization without substance. Disagreements over the thesis are futile. They reflect preferences for different conceptualizations which are ultimately equivalent. |
