3. kin selection provides a plausible framework for understanding our results. Kin selection models predict that dispersers benefit from the success of their resident relatives, and that dispersal primarily arises to mitigate competition among kin.
1. Using quantitative genetic and pedigree-based approaches, we estimated the heritability, intragenerational and multigenerational selection of dispersal.
4. Our results also suggest that the "paradox of stasis” may partly stem from limited temporal resolution in studies. Compensatory mechanisms over generations may mask evolutionary trajectories when analyses focus solely on short-term fitness proxies.
