Positive Selection Drove the Adaptation of Mitochondrial Genes to the Demands of Flight and High-Altitude Environments in Grasshoppers

Abstract excerpt

Mitochondrial adaptions to flight and to high-altitudes remain largely unexplored in invertebrates. In grasshoppers, some related species fly and some do not; other related species are endemic to the Tibetan Plateau and some are not. These species are therefore ideal models in which to investigate whether positive selection on mitochondrial genes drives adaptation. Our molecular evolutionary analysis of the 13...
