Groups containing juveniles had higher relatedness than adult-only groups, as juveniles were commonly found in aggregations with at least one parent and/or sibling. We found that these lizards are highly sedentary and that groups often form through the delayed dispersal of offspring. We combined a 5-year mark-recapture study with a DNA microsatellite analysis of relatedness in a social lizard (Xantusia vigilis) to examine the formation and stability of kin groups. However, comparing kin dynamics in birds and mammals to social reptiles provides the opportunity to identify selective factors that promote independent origins of kin sociality across vertebrates. Studies of social birds and mammals have produced extensive theory regarding the formation and dynamics of kin-based social groups in vertebrates.
