Phenotypic selection on a heritable size trait revisited.
One of evolutionary biology's most persistent puzzles is the fact that apparent directional selection on a heritable trait in a natural population often does not produce a selection response. We tested three possible explanations for this problem using data on body size of more than 23,000 indi...
