New research from Devi Stuart-Fox (University of the Witwatersrand, South Africa, and The University of Melbourne, Australia) and Adnan Moussalli (University of KwaZulu Natal, South Africa, and Museum Victoria, Melbourne, Australia) has established that social signaling, rather than camouflage, drives the evolution of this color change.
