In this chapter we employ logistic regression and Darwinian dynamics to explore how a behavior with a crucial physiological function might be co-opted to function as a coping behavior in response to stress generated by the presence of predators. This study was initially reported in the Journal of Biological Dynamics in 2012 by senior researchers Shandelle Henson, Lynelle Weldon, and James Hayward, and students Daniel Greene, Libby Megna, and Maureen Serem [23].
