O'Connor suggests that, in contrast to biomedical research, ecology has lagged behind the surging advances of most of the life sciences.1 O'Connor's main argument for the putative lag of ecological sciences is the failure to distinguish form from substance in the hypothetico-deductive research that drives most current scientific endeavors. Categorizing most ecological sciences as descriptive and poss
