Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.ABSTRACT Caves are extreme environments that impose stringent selective pressures on organisms. Consequently, many cave dwellers show extreme adaptations such as the loss of eyes, depigmentation, and a low resting metabolic rate. Yet, how the initial stages of adaptation to these extreme environments take place remains poorly understood.
