     The Snake Detection Theory (Isbell 2006, 2009) argues that snakes were so important as selective pressures on primates that they exerted two pulses of major evolutionary change. The first pulse favored the origin of primates, with their ancestral visual innovations; the second pulse involved the origin of anthropoids and variation in visual systems among primates on different landmasses. In this interdisciplinary symposium we use a broad approach involving molecular systematics, paleobiogeography, herpetology, ecology, behavior, and visual neuroscience to bring to attention the impact of snakes on primates now and over evolutionary time.
