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.
2. We show that dispersers experienced reduced individual fitness during their lifetime, yet their genetic lineages persisted longer through generations. This antagonistic interplay between short- and long-term selection pressures explains how dispersal polymorphism is maintained in the population.

Happy to see our new paper published today in @royalsocietypublishing.org B !
In it, we present an extensive work on the evolution of dispersal in a natural population of common lizards (Zootoca vivipara) 🦎

Abstract. Dispersal is a key process that shapes the dynamics, genetic structure and adaptive potential of natural populations, yet persistence of its poly
