用简约法对蛋白质、氨基酸和DNA核苷酸序列数据进行的系谱重建为从脊椎动物纲、真兽目到人总科各属在分类水平上的分支模式提供了新的证据。从氨基酸序列数据组哺乳动物与始祖龙(即Aves+鳄鱼)、羊栖生物与两栖动物、四足动物与真骨动物构建的最小长度树。在哺乳动物中，埃登目和Paenungulata(例如，喙形目)似乎是最古老的与其他真兽目动物分开的。另一个真兽纲的超目分支由偶蹄目、鲸目和腹足目组成。三分之一始终含有灵长类动物。拉格莫拉和图帕亚。食肉目、翼手目、食虫目和啮齿目等目的分支位置并没有被目前仍然稀少的序列数据所很好地解析。然而，最近基因克隆和核苷酸测序技术的巨大进步为扩大序列数据的主体开辟了道路，使之有可能解决有关现存哺乳动物系统学的几乎任何问题。类人猿属提供了一个例子。根据线粒体DNA核苷酸序列构建的最小长度树非常强烈地将潘、人和大猩猩聚为人亚科，然后将人亚科和Ponginae(Pongo)聚为人科，作为Hylobatidae(Hylobates)的姐妹家族。随着核基因千碱基测序的进展，人的三分体应该会被分解成两个二叉的分支。
Genealogical reconstructions carried out by the parsimony method on protein amino acid and DNA nucleotide sequence data are providing fresh evidence on cladistic branching patterns at taxonomic levels from the classes of Vertebrata and orders of Eutheria to the genera of Hominoidea. Minimum length trees constructed from amino acid sequence data group Mammalia with Archosauria (i.e., Aves plus Crocodilia), Amniota with Amphibia, and Tetrapoda with Teleostei. Within Mammalia, Edentata and Paenungulata (e.g., Proboscidea) appear as the most anciently separated from other eutherians. Another superordinal eutherian clade consists of Artiodactyla, Cetacea, and Perissodactyla. A third consistently contains Primates. Lagomorpha, and Tupaia. The cladistic positions of such orders as Carnivora, Chiroptera, Insectivora, and Rodentia are not well resolved by the currently still sparse body of sequence data. However, recent dramatic progress in the technology of gene cloning and nucleotide sequencing has opened the way for so enlarging the body of sequence data that it should become possible to solve almost any problem concerning the phylogenetic systematics of extant mammals. An example is provided by hominoid genera. Minimum length trees constructed from mitochondrial DNA nucleotide sequence data very strongly group Pan, Homo, and Gorilla into Homininae and then join Homininae and Ponginae (Pongo) into Hominidae as the sister family of Hylobatidae (Hylobates). Resolution of the hominine trichotomy into two dichotomous branchings should be forthcoming as kilobase sequencing of nuclear genes progresses.
