在现存鸟类（新鸟目）的基础分支中，“陆禽”或鸟形目（鸟形目，鸟形目）是种类最多的。对大多数假定的galliform属的100多个形态特征进行的分类分析证实，megapodes（“土堆建造者”；megapodidae）是该目中最基础的分支。它们之后依次是curassows， guans和chachalacas (Cracidae)，它们构成了所有其他现存的Galliformes（即phasiano总科）的姐妹群。在这个庞大的“phasianoid”分支中，分析表明珍珠鸡（Numididae）是最基础的分类单元，尽管根据所采用的形态学特征并不能严格支持这个“家族”的单系性。通过这一分析，我们还发现了另一个主要分支，包括传统的新世界鹌鹑（Odontophoridae）和旧大陆鹌鹑（'Perdicini'），但形态学特征明确支持前者的单系性。在其余的鸡类分类群中，包括松鸡（Tetraonidae），火鸡（即Meleagris/Agriocharus spp.）以及其他“鸡类”（即孔雀，Pavo, Afropavo, Rheinardia， Argusianus和Polyplectron spp.）的关系在形态学特征的基础上仍未得到解决，但主要分支的单系性在这里得到了支持。尽管存在许多重要的差异，特别是关于非鹌鹑类的关系，但这种形态系统发育（枝系）分析的结果与传统分类和现有的镓状系统发育关系的分子假设大致一致。(C) 2003伦敦林奈动物学会，林奈动物学会学报，2003,13(3):227-244。
Of the basal clades of extant birds (Neornithes) the 'landfowl' or galliforms (Aves, Galliformes) are the most speciose. Cladistic analysis of more than 100 morphological characters coded at the generic level for most putative galliform genera confirms that the megapodes ('mound builders'; Megapodiidae) are the most basal clade within the order. They are followed successively by the curassows, guans and chachalacas (Cracidae), which comprise the sister-group to all other extant Galliformes (i.e. Phasianoidea). Within this large 'phasianoid' clade, analyses suggest that the guineafowl (Numididae) are the most basal taxon, although monophyly of this 'family' is not strictly supported on the basis of the morphological characters employed. An additional major clade within the phasianoid Galliformes is recovered by this analysis, comprising the traditional groupings of New World quails (Odontophoridae) and Old World quails ('Perdicini'), yet only monophyly of the former is supported unambiguously by morphological characters. Relationships within the remainder of the phasianoid taxa, including the grouse (Tetraonidae), turkeys (i.e. Meleagris/Agriocharus spp.) as well as other 'pavonine' galliforms (i.e. peafowl; Pavo, Afropavo, Rheinardia, Argusianus and Polyplectron spp.) remain largely unresolved on the basis of morphological characters, yet monophyly of the major subdivisions is supported here. Although there are a number of important differences, especially with regard to relationships within the nonquail phasianoids, the results of this morphological phylogenetic (cladistic) analysis are broadly congruent both with traditional classifications and existing molecular hypotheses of galliform phylogenetic relationships.
