Comparative psychology is still alive but may be losing relevance

Abstract

Greenberg et al., in their perspective on the current state and fate of comparative psychology, present convincing data that the field is viable and that comparative psychologists are making important contributions to the research literature. The central feature of the field is its emphasis upon evolution. This is also its weakness since advances in genetic techniques permit researchers to create laboratory animals that have no counterpart in the natural world, and thus have no evolutionary history. These "unnatural" animals are widely used in behavioral, biological, and medical studies, but the findings cannot be interpreted within a comparative psychology framework. As the use of these preparations expand, the relevance of comparative psychology diminishes.
