Divergence, Sensory Drive, and Speciation
Martin Stevens · Oxford University Press eBooks · 2013
Sensory and communication systems are crucial in leading to divergence between populations. This chapter discusses the role of the environment, sensory systems, and signals in divergence between populations and even speciation; how we are starting to understand both the molecular mechanisms underlying some of these changes, as well as the selective advantage incurred; how various factors can lead to divergence and speciation, including reproductive character displacement, disruptive selection, so-called magic traits, predation pressure, and sexual selection; how these factors operate in different groups and sensory modalities; and how the environment may cause divergence and speciation in some groups through the process of sensory drive.
