Levels of steroid hormone (e.g., testosterone, corticosterone) are related to the dynamics and outcome of aggressive disputes in many animals. However, are steroid hormone levels the cause or the consequence of aggressive interactions? For example, do animals with high testosterone levels become dominant, or does dominance status result in elevated testosterone levels? Devise an experiment to test these two alternatives.
