英文关键词：modern Homo sapiens Mitochondrial Eve ancient DNA divergence molecular clock

中文摘要：美国学者宣称现代人类线粒体DNA可能来自20万年前一位非洲妇女,这就是"线粒体夏娃理论"。但有学者指出了此理论的不完善性,虽然分子钟可以用来确定古DNA序列的分化时间,但分子钟的运动并不是普遍匀速的,每一特定的分子序列都有独特的进化曲线,所以说人类的进化是一个复杂的过程。

英文摘要：ABSTRACT: Alan Wilson and his colleagues announced in 1987 that" (modern human) mitochondrial DNAs stem from one woman who is postulated to have lived about 200, 000 years ago, probably in Africa." Mitochondrial Eve has become a popular name for the common ancestor of modern humanity. Molecular clocks can be used to estimate the time of divergence of ancestral DNA sequences, but there is no universal molecular clock, so calibration is important.
