Research overview: genetics and desert adaptation of the sand cat

The sand cat is a small felid of the deserts of North Africa, the Middle East, and Central Asia, with adaptations for life in extreme arid heat. This overview surveys its placement within the Felis lineage, the limited genetic data on its population structure across a vast and fragmented desert range, and the physiological adaptations, such as water conservation and heat tolerance, that may have a genetic basis. It discusses the challenges of studying a cryptic desert cat, the potential for distinct regional populations, and how comparative genetics of desert-adapted felids could illuminate the molecular basis of survival in one of the planet's harshest environments.
