Phylogeographic patterns and genetic clades in the lion (Panthera leo)

This study used mitochondrial and nuclear markers across the lion's range to map genetic structure and found a deep division between northern lions (West and Central Africa plus Asia) and southern lions (East and Southern Africa). The authors delineated genetic clades that did not match the traditional African-versus-Asian split, showing instead that West and Central African lions group with the Asiatic lion. These results provided key evidence for the two-subspecies arrangement, Panthera leo leo for northern populations and Panthera leo melanochaita for southern ones, later adopted by the Cat Classification Task Force. The paper reshaped lion taxonomy and carried strong conservation implications, since the northern clade is the most threatened, highlighting populations whose distinctiveness had been overlooked under earlier classifications.
