Abstract

Several recent studies have confirmed that mitochondrial DNA variation and evolution are not consistent with the neutral theory of molecular evolution and might be inappropriate for estimating effective population sizes. Evidence for the action of both positive and negative selection on mitochondrial genes has been put forward, and the complex genetics of mitochondrial DNA adds to the challenge of resolving this debate. The solution could lie in distinguishing genetic drift from ‘genetic draft’ and in dissecting the physiology of mitochondrial fitness.
