Here we present a DNA sequence study that incorporates intraspecific variation from all five genera of hominoids (apes and humans). Recently it has been claimed that using single individuals to analyze species' relationships might be misleading if within-species variation is great. Our results indicate that despite high intraspecific variation in mitochondrial cytochrome oxidase subunit II gene sequences of some hominoids, humans and chimpanzees are nonetheless significantly most closely related. We also report the observation that variation within the gorilla species exceeds that between common and pygmy chimpanzee species, a finding with implications for conservation. In contrast, humans are less mitochondrially diverse than lowland gorillas inhabiting western Africa.
在此,我们展示了一项DNA序列研究,该研究纳入了所有五种类人猿(猿类和人类)属内的种内变异。最近有人声称,如果物种内部变异很大,那么使用单个个体来分析物种间的关系可能会产生误导。我们的结果表明,尽管一些类人猿的线粒体细胞色素氧化酶亚基II基因序列存在高度种内变异,但人类和黑猩猩仍是显著关系最密切的。我们还报告了这样的观察结果:大猩猩物种内的变异超过了普通黑猩猩和倭黑猩猩物种之间的变异,这一发现对保护工作具有启示意义。相比之下,人类线粒体的多样性低于居住在西非的低地大猩猩。
