Genomic legacy of the African cheetah

This study sequenced the cheetah genome and documented its extreme genetic uniformity, a legacy of severe historical bottlenecks. The authors found very low genome-wide diversity, including in immune-related genes, consistent with the cheetah's well-known reproductive and disease vulnerabilities. While primarily a conservation-genomics paper, it provided a reference genome and population data relevant to cheetah subspecies and phylogeography. For taxonomy, the work informs how the cheetah's lineage, part of the puma group alongside the jaguarundi, is structured, and complements studies delimiting African and Asiatic cheetah subspecies. The piece is a landmark in understanding how a cat lineage can persist despite minimal genetic variation, and it underpins discussions of the cheetah's distinctiveness and its placement within the puma lineage of the felid family tree.
