Abstract

vallortigara & rogers's (v&r's) proposal that directional asymmetries evolved under social pressures raises questions about the ontogenetic mechanisms subserving the alignment of asymmetries in a population. neuro-ontogenetic principles suggest that epigenetic factors are decisively involved in the determination of individual lateralization and that genetic factors align their direction. clearly, directional asymmetry has an epigenetic trait.
