雀形目（雀形目）是一种种类繁多、分布广泛的鸟类，被认为起源于旧大陆。使用线粒体DNA（mtDNA）序列数据，包括细胞色素B和ND 2基因的组合内的系统发育关系进行了研究。我们的内组采样包括54种代表17 20个假定的turdine属。通过最大简约法和最大似然法得到的系统发育树基本一致。大部分的Turdine类群采样可以放置到六个支持的分支之一。我们的数据表明，一个多系动物，可分为至少两个（非洲-亚洲和澳大利亚-亚洲）的主要分支。Turdus属，目前公认的，是并系的，但形成了一个很好的支持分支，增加了三个主要单型属（Platycichla，Nesocichla和Cichlherminia）。我们确定了一个专门的新世界分支，包括单系Catharus，Hylocichla，Cichlopsis，Entomodestes，Ridgwayia和Ixoreus。形态和行为上不同的属Sialia，Myadestes和Neocossyphus的成员意外地形成了一个基础分支。使用多个外群的选择，我们表明，这组是远亲，但明确的姐妹组，其余的Turdines采样。该鸟似乎是一个相对古老的鸣禽谱系，起源于中新世中期至晚期。如果Turdinae确实是旧世界的起源，我们的数据表明新世界至少有三次独立的入侵。(C)2004年爱思唯尔公司All rights reserved.
The true thrushes (Passeriformes: Muscicapidae, subfamily Turdinae) are a speciose and widespread avian lineage presumed to be of Old World origin. Phylogenetic relationships within this assemblage were investigated using mitochondrial DNA (mtDNA) sequence data that included the cytochrome b and ND2 genes. Our ingroup sampling included 54 species representing 17 of 20 putative turdine genera. Phylogenetic trees derived via maximum parsimony and maximum likelihood were largely congruent. Most of the Turdine taxa sampled can be placed into one of six well supported clades. Our data indicate a polyphyletic Zoothera which can be divided into at least two (Afro-Asian and Austral-Asian) main clades. The genus Turdus, as presently recognized, is paraphyletic but forms a well supported clade with the addition of three mostly monotypic genera (Platycichla, Nesocichla, and Cichlherminia). We identify an exclusively New World clade that includes a monophyletic Catharus, Hylocichla, Cichlopsis, Entomodestes, Ridgwayia, and Ixoreus. Members of the morphologically and behaviorally distinct genera Sialia, Myadestes, and Neocossyphus unexpectedly form a basal clade. Using multiple outgroup choices, we show that this group is distantly related, but unequivocally the sister group to the remaining Turdines sampled. The Turdinae appear to be a relatively old songbird lineage, originating in the mid to late Miocene. If the Turdinae are indeed Old World in origin, our data indicate a minimum of three separate invasions of the New World. (C) 2004 Elsevier Inc. All rights reserved.
