Human evolution and the mitochondrial genome

Abstract

The use of mitochondrial DNA (mtDNA) continues to dominate studies of human genetic variation and evolution. Recent work has re-affirmed the strict maternal inheritance of mtDNA, yielded new insights into the extent and nature of intra-individual variation, supported a recent African origin of human mtDNA, and amply demonstrated the utility of mtDNA in tracing population history and in analyses of ancient remains.
