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...

Chromosomal inversions accelerate genetic evolution and drive ecological speciation across an island gradient.

The results demonstrate that genomic architecture actively dictates evolutionary speed, suggesting that certain lineages boosted by structural variants may bypass the typical constraints of purifying selection to rapidly exploit vacant ecological opportunities.
