Abstract

vallortigara & rogers (v&r) propose a fundamental role of the environment in determining population-level lateralisation and suggest that genes play no primary function in this phenomenon. here i argue that genes involved in the coordination of visceral organ laterality and in coupling of different forms of lateralisation do play a role in the control of lateralisation within the population.
