Evolutionary replacement of components in a salamander pheromone signaling complex: more evidence for phenotypic-molecular decoupling.

Evolution; international journal of organic evolution - 1 Jan 2007

Palmer Catherine A, Watts Richard A, Houck Lynne D, Picard Amy L, Arnold Stevan J

Abstract excerpt

In this article we explore the evolutionary history of a functional complex at the molecular level in plethodontid salamanders. The complex consists of a proteinaceous courtship pheromone, a pheromone-producing gland on the male's chin, and a set of behaviors for delivering the pheromone to the female. Long-term evolutionary stasis is the defining feature of this complex at both the morphological and behavioral...
