松鸡亚科（Tetraoninae）是鸡形目（Galliformes）中的一个泛北极类群，其特征是对寒冷环境的形态适应和与精心求偶相关的行为特征。在这里，我们调查的关系，17 tetraonines和其他12 galliform物种使用线粒体12 S和ND 2序列数据。我们发现支持最近的系统发育分类，将属Dendragapus分为两个属，Falcipennis和Dendragapus。此外，我们发现支持一个tetraonine分支，其中第一个分歧是Bonasa umbellus和所有其他之间，其次是Bonasa bonasial Bonasa sewerzowi分支和其余tetraonines之间的分歧。Falcipennis canadensis是四个Tetrao物种的姐妹，Centrocercus属是Dendragapus obscurus/Tympanuchus分支的姐妹。我们的数据表明，在五个公认的鸡形科中，Cracidae和Megapodiidae的基础位置。我们还发现了强有力的支持Phasianidae的单系，虽然相对位置的Numididae和Odontiphoridae仍然没有解决。我们使用最大似然法推断年龄为37百万年的分歧Numidididae和Phasianidae和28百万年的分歧Tetraoninae和Meleagris gallopavo。这些估计必须被视为初步的，因为它们取决于分子进化速度和准确的化石日期的测试。(C)2002 Elsevier Science（美国）。All rights reserved.
The avian subfamily Tetraoninae (grouse and ptarmigan) is a Holarctic group in the order Galliformes distinguished by morphological adaptations to cold environments and behavioral traits associated with elaborate courtship. Here we investigate the relationships of 17 tetraonines and 12 other galliform species using mitochondrial 12S and ND2 sequence data. We found support for the recent phylogenetic classification that separates the genus Dendragapus into two genera, Falcipennis and Dendragapus. In addition, we found support for a tetraonine clade in which the first divergence is between Bonasa umbellus and all others, followed by divergence between a Bonasa bonasial Bonasa sewerzowi clade and the remaining tetraonines. Falcipennis canadensis is sister to a clade with four Tetrao species, and the genus Centrocercus is sister to a Dendragapus obscurus/Tympanuchus clade. Our data indicate a basal position for Cracidae and Megapodiidae among the five recognized galliform families. We also found strong support for the monophyly of Phasianidae, although the relative positions of Numididae and Odontiphoridae remains unresolved. We use a maximum likelihood approach to infer ages of 37 mya for divergence of Numididae and Phasianidae and 28 mya for the divergence of Tetraoninae and Meleagris gallopavo. These estimates must be viewed as tentative as they depend on tests of rates of molecular evolution and accurate fossil dates. (C) 2002 Elsevier Science (USA). All rights reserved.
