高等动物的线粒体DNA(MtDNA)正在迅速成为一个分子水平上具有良好特性的遗传系统。在这篇论文中，我将重点转移到考虑生物进化中可以通过线粒体DNA分析解决的问题。这是第一次有可能从经验上估计母系起源；确定产生杂交的杂交的方向性；以及研究不同女性人口统计和生活史的群体遗传后果。从线粒体DNA获得的数据可能特别适合于种群遗传结构、扩散和历史动物地理学的研究。雌性介导的mtDNA的克隆传播也激发了新的思维方式，即在其他有性繁殖的种群中，无性血统的共同祖先的时间；mtDNA-核DNA相互作用与生殖隔离的可能相关性；以及相对于特定类型的遗传特征，相关物种的系统发育地位的真正意义。对这些主题和其他主题进行了回顾。
Mitochondrial DNA (mtDNA) in higher animals is rapidly becoming a well characterized genetic system at the molecular level. In this paper, I shift the focus to consider questions in organismal evolution that can be addressed by mtDNA assay. For the first time, it is possible to estimate empirically matriarchal phylogeny; to determine directionality in crosses producing hybrids; and to study the population genetic consequences of varying female demographies and life histories. The data obtainable from mtDNA may be especially well suited for studies of population genetic structure, dispersal, and historical zoogeography. The female-mediated, clonal transmission of mtDNA is also stimulating new ways of thinking about times to common ancestry of asexual lineages within otherwise sexually reproducing populations; about the possible relevance of mtDNA-nuclear DNA interactions to reproductive isolation; and about the very meaning of the phylogenetic status of related species with respect to particular kinds of genetic characters. These and other topics are reviewed.
