Mitochondrial DNA sequences of both ribosomal RNA genes and three adjacent transfer RNA genes were obtained for the three extant subfamilies of antlered deer (Cervinae, Muntiacinae, and Odocoileinae) as well as for their antlerless sister group Hydropotinae (family Cervidae). Phylogenetic analysis of these sequences (each nearly 2.7 kilobase pairs in length) supports a cervine/muntiacine clade to the exclusion of odocoileines. These results are statistically significant, stable, and congruent with some independent data. Our mitochondrial DNA sequences, when coupled with other information, indicate that the earliest fossil antlered deer are not closely related to living muntiacines or any other contemporary subfamily. From this information, we hypothesize an Old World, Late Miocene origin of Odocoileinae.
我们获得了鹿科三个现存亚科(鹿亚科、麂亚科和空齿鹿亚科)以及它们无角的姐妹类群獐亚科(鹿科)的核糖体RNA基因和三个相邻转运RNA基因的线粒体DNA序列。对这些序列(每个长度近2.7千碱基对)进行系统发育分析,支持鹿亚科/麂亚科分支,不包括空齿鹿亚科。这些结果具有统计学意义、稳定性,并且与一些独立数据一致。我们的线粒体DNA序列,结合其他信息表明,最早的化石有角鹿与现存的麂亚科或任何其他当代亚科没有密切关系。根据这些信息,我们推测空齿鹿亚科起源于旧世界晚中新世。
