Data from: Parallel molecular evolution in pathways, genes, and sites in high-elevation hummingbirds revealed by comparative transcriptomics

Marisa C.W. Lim, Christopher C. Witt, Catherine H. Graham & Liliana M. Davalos
High-elevation organisms experience shared environmental challenges that include low oxygen availability, cold temperatures, and intense UV radiation. Consequently, repeated evolution of the same genetic mechanisms may occur across high-elevation taxa. To test this prediction, we investigated the extent to which the same biochemical pathways, genes, or sites were subject to parallel molecular evolution for 12 Andean hummingbird species (family: Trochilidae) representing several independent transitions to high elevation across the phylogeny. Across high-elevation species, we discovered...
