Dating the Colonisation and Source of Adaptive Genetic Variation in the Iago Sparrow (Passer iagoensis)

ABSTRACT Ancestral adaptive variation is thought to play an important role in facilitating adaptation to insular environments. However, to properly evaluate its role, we need to determine the age of genetic variation. In this study, we investigate the Iago sparrow ( Passer iagoensis ), a generalist endemic to the Cabo...

The Genome-Wide Effect of Drift and Selection over a Single Generation

The relative importance of genetic drift versus selection to evolutionary change has long been debated. This debate has mainly focused over long-time-scales (e.g. hundreds of thousands of generations), leaving the question of short-term evolutionary change relatively unaddressed. Our knowledge about the effects of sele...
