Regressive evolution of morphological features is a common evolutionary event. However, the relationship between structural degeneration and loss of physiological function is often unclear because the ancestral and derived states of a character are usually not available for comparison. Here, we report studies on retinomotor rhythms during development of the blind cavefish Astyanax mexicanus, a single teleost species consisting of a sighted surface-dwelling form (surface fish) and several blind… CONTINUE READING
