Abstract

Apparently factual disagreement on the level 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
