Methodological problems in evolutionary biology III. Selection and levels of organization
Abstract
Apparently factual disagreement on the level(s) at which selection operates often results from different interpretations of the term selection. Attempts to resolve terminological problems must come to grips with a dilemma: a narrow interpretation of selection may lead to a restricted view on evolution; a broader, less precise, definition may wrongly suggest that selection is the centre of a unified, integrated theory of evolution. Different concepts of selection, therefore, should carefully be kept apart.
