Abstract

Despite great advances in understanding genetic mechanisms, there still exists a bias toward equating genes with innate modules that determine important developmental events. But genes are equally relevant to understanding developmental plasticity shaped by ecological events. In other words, the term 'genetic inheritance' does not specify ontogenetic mechanisms. Here we present a case history of a species assumed to be under the control of prespecified genetic wiring to direct critical behavioral events such as communication and mating. We show, however, that exogenetic processes stemming from the species's ontogenetic niche provide an alternative view of the flexibility of development especially with respect to behavioral performance.
