To uncover the selective forces shaping lifespan evolution, we investigate the genomic</p><p>basis underlying adaptations to seasonal habitat desiccation in African killifishes,</p><p>identifying the genetic variants associated with positive and relaxed purifying selection</p><p>in 45 killifish species (4 reference genomes assembled) and 231 wild individuals distributed throughout sub-Saharan</p><p>Africa.
