Abstract

Natural selection of asymmetric traits operates at multiple levels. Some asymmetric traits (like having a dominant eye) are tied to more universal aspects of the environment and are coded genetically, while others (like pedestrian turning biases) are tied to more ephemeral patterns and are largely learned. Species-wide trends of asymmetry can be better modeled when different levels of natural selection are specified.
