Research overview: the snow leopard genome and big cat adaptation

Sequencing the snow leopard genome alongside those of the tiger and lion advanced both big cat phylogenetics and the study of high-altitude adaptation. This overview surveys how the snow leopard genome revealed signatures of adaptation to cold, hypoxic mountain environments, including genes related to oxygen transport and metabolism. It discusses how comparative genomics placed the snow leopard within Panthera and contributed to detecting introgression among big cats. The piece explains why the snow leopard is a valuable model for understanding how cats colonized extreme habitats and how its genome informs both its evolutionary history and its conservation. It connects to the broader theme that whole-genome data simultaneously resolve relationships and illuminate the adaptive biology underlying a species' distinctive ecology, here the snow leopard's mastery of the high mountains of Asia.
