猫科猫科动物的分子遗传学是利用两个线粒体基因，细胞色素B和12 S rRNA推导的。采用加权最大简约法和邻接法估计的最小进化法对20种猫科动物进行了系统发育分析。363 bp的细胞色素B和376 bp的12 S rRNA基因的序列分析得到的平均成对相似性值之间的猫科动物从94至99%，从85至99%，分别。系统发育重建支持更近的，intralineage协会，但未能完全解决interlineage关系。这两个基因都产生了猫科动物物种的单系群，但在兔兔的位置上有所不同。豹猫谱系代表了猫科动物中的早期分歧，豹猫和马吉、杰弗里猫和科科德以及潘帕斯草原猫和虎斑猫之间存在着密切的联系。猫科动物进化的相对新近度，祖先的多态性的存在下，和外群的拓扑根的位置的影响的影响进行了讨论。(C)出版社：Academic Press，Inc.
Molecular phylogeny of the cat family Felidae is derived using two mitochondrial genes, cytochrome b and 12S rRNA. Phylogenetic methods of weighted maximum parsimony and minimum evolution estimated by neighbor-joining are employed to reconstruct topologies among 20 extant felid species. Sequence analyses of 363 bp of cytochrome b and 376 bp of the 12S rRNA genes yielded average pair-wise similarity values between felids ranging from 94 to 99% and from 85 to 99%, respectively. Phylogenetic reconstruction supports more recent, intralineage associations but fails to completely resolve interlineage relationships. Both genes produce a monophyletic group of Felis species but vary in the placement of the pallas cat. The ocelot lineage represents an early divergence within the Felidae, with strong associations between ocelot and margay, Geoffroy's cat and kodkod, and pampas cat and tigrina. Implications of the relative recency of felid evolution, presence of ancestral polymorphisms, and influence of outgroups in placement of the topological root are discussed.
