The Northern Eurasia origin hypothesis is one key pointin the evolutionary model. This indicates that species riginated in Northern Eurasia. Perdix, belonging to Phasianidae of Galliformes,is a valuable type of wildfowl widely distributed Northern Eurasia and containsthree species. This mini-review discusses the taxonomic status, phylogeny, and originof Perdix. Morphological and molecularevidence suggest that the three species, P. hodgsoniae, P. dauuricae and P. perdix, form a monophyletic group and they should be classified as “pheasant” ratherthan “quail.” The current review also shows that results were affected by the methodsselected for data analysis. A taxonomic category should contain as many speciesas possible, have a clear system history, remain evolutionarily stable, and lackadaptive radiation. Appropriate type, number and length of genes are important asmolecular markers and out-group affects the bootstrap support value. P. hodgsoniae is located at the root of thephylogenetic tree and has the phenotype of ancestral Perdix. The genus Perdix mayoriginate in the Qinghai-Tibet Plateau andexpanded into high latitude areas, towards the northern plateau. This phylogeneticand evolutionary statement differs from the Eurasian origin hypothesis.
