ON THE EVOLUTION OF ECOLOGICAL IDEAS: PARADIGMS AND SCIENTIFIC PROGRESS

Abstract

We introduce a heuristic model for studying the evolution of ecological ideas based on Thomas Kuhn's concept of the development of scientific paradigms. This model is useful for examining processes leading to ecological progress and the elaboration of ecological theories. Over time, ecological knowledge diverges and evolves as data are collected that either refute or support the current trajectories of accepted paradigms. As a result, the direction of ecological research continuously branches out into new domains leading to increased ecological understanding. Unfortunately, heightened ecological un- derstanding also builds impediments to future progress. Increased specialization and the parallel evolution of seemingly independent subdisciplines generally compel researchers to become increasingly canalized. Specialization also accelerates the expansion of the ecological literature, making it difficult for researchers to track developments in their own subdisciplines, let alone the general field of ecology. Furthermore, specialization inherently focuses attention on contemporary research and hastens the erasure of memory of historical contributions to modern ecology. As a result, contemporary ecologists are in danger of losing touch with their historical roots and face a greater likelihood of recycling ideas and impeding real scientific momentum. Enhancing our historical perspective on the evolution of ecological ideas will be key in overcoming the negative consequences of progress and safeguarding the continued advancement of ecology.
