Research interests


Evolution of diverse personality traits in human

Human adaptation and diseases as its evolutionary consequence are of quite interest. So far I have focused on the evolution of genetic variants related to psychiatric disorders or personality traits and conducted comparative genomic analyses by molecular evolutionary approaches. In our previous study (Sato & Kawata 2018, Evol. Lett.), we showed that natural selection have played an important role on the maintenance of psychiatric disease risk alleles of VMAT1 gene within populations, which could underlie our psychological diversity including psychiatric disorders and personality traits. Moreover, our recent experimental study (Sato et al., submitted) showed that neurotransmitter uptake of VMAT1 had evolutionarily declined, possibly suggesting that higher levels of anxiety could be favored during the early phase of human evolution. In my ongoing work, I am trying to evaluate the fitness effects of the genetic polymorphism in VMAT1 gene using large cohort dataset of Japanese population and reveal evolutionary mechanism behind human psychological diversity.
