No hybrid snowcocks in the Altai-Hyper-variable markers can be problematic for phylogenetic inference.

A recent article in Ecology and Evolution featured the discovery of hybrid snowcocks () and speculated on the hybrid origin of an extant species (). Comprehensive re-analyses of original data from the latter paper reliably refute the phylogenetic hypothesis taken as firm evidence of a past hybridization event in these birds. The new re-analyses showed that there is no evidence of hybridization in these snowcocks from the data available so far.
