Evolution of sociability: genome scans and gene validation

Sociability, defined as individuals' tendencies to affiliate with conspecifics, has positive associations with fitness in animals as well as with health, well-being and longevity in humans. Despite its importance, we still have limited information about natural genetic variation in sociability. As part of a long- term initiative to address this knowledge gap, we quantified changes in allele frequencies in adult fruit flies (Drosophila …
