FA may be visualized as the base on which natural selection acts, originating either in directional asymmetry (DA, that is

High levels of developmental integration found in our dataset could explain the overall low levels of asymmetry found in our study. © Koninklijke Brill NV, Leiden, 2010.

ideal symmetry, i.e. fluctuating asymmetry (FA), can reflect developmental instability among the individuals of a population (Van Valen, 1962). Therefore, the less developmentally stable an organism is, the more likely is to deviate from perfect symmetry. However, an organism has the ability to correct
