S-01: Sensory genetics, ecology and evolution of primates

8/21 9:00-12:00 会場:Room 1
企画者:Shoji Kawamura (The University of Tokyo), Hiroo Imai (Kyoto University)


    Primates are generally regarded as visually-oriented mammals, trading a sense of smell for good sight. However, recent studies have questioned this simplistic view and it is not well understood the extent to which senses have evolved interactively, independently or in concert in primates, including humans. For example, the number of olfactory receptor genes is not as clearly differentiated between species with different color vision as once asserted. Among senses, receptors of stimuli for vision, olfaction and bitter/sweet/umami tastes all belong to the G-protein coupled receptor (GPCR) family, for which the genetic mechanism of signal perception is well understood. Thus, it is now possible to explore the evolutionary correlation among different senses in primates by studying these receptor groups. In this symposium, we invite investigators on the cutting edge of the sensory genetics, ecology and evolutionary study on primates to exchange newest findings and discuss the future directions of studies on sensory evolution of humans and other primates.
