Because of the independent origins of evolutionary ecol-ogy and many areas of applied biology, they initially evolved in isolation from each other, with each develop-ing its own terminology, research approaches, societies, and publications. Such fields as economic entomology, plant pathology, parasitology, microbiology, and even medicine have a wealth of information that could aid in theory development in evolutionary ecology; but for a long time this has largely been ignored by evolutionary ecologists. Recently, however, there has been an increase in cross-pollination among fields. For example, coevolu-tionary biologists initially learned about gene-gene inter-actions by examining older studies by plant pathologists (Flor, 1956), and evolutionary concepts are finally being applied to the study of medicine (Ewald, 1994)
