我们确定的同源0.9 kb片段的线粒体DNA（mtDNA）的核苷酸序列来自四种旧世界的猴子，一种新世界的猴子，和两种原猴。利用这些核苷酸序列和5个类人猿的同源序列，我们构建了4个灵长类动物类群的系统发育树。所获得的进化树与以往研究中构建的进化树基本一致。我们的研究结果还表明，与旧世界的猴子相比，人类（人类、黑猩猩和大猩猩）mtDNA的核苷酸替换速率可能有所减缓。线粒体基因的这种进化特征与核基因中发现的相似。
We determined nucleotide sequences of homologous 0.9-kb fragments of mitochondrial DNAs (mtDNAs) derived from four species of old-world monkeys, one species of new-world monkeys, and two species of prosimians. With these nucleotide sequences and homologous sequences for five species of hominoids, we constructed a phylogenetic tree for the four groups of primates. The phylogeny obtained is generally consistent with evolutionary trees constructed in previous studies. Our results also suggest that the rate of nucleotide substitution for mtDNAs in hominines (human, chimpanzee, and gorilla) may have slowed down compared with that for old-world monkeys. This evolutionary feature of mitochondrial genes is similar to one found in nuclear genes.
