What is the primary behavioral adaptation that leads *Xerus* squirrels to spend most of their active time on the ground rather than in trees?
Answer
Their lifestyle is characterized by diurnal habits in open, often arid, environments, unlike tree-dwelling relatives
The *Xerus* genus is fundamentally defined by its terrestrial existence, contrasting sharply with tree-dwelling relatives. These ground squirrels are diurnal, meaning they are active during daylight hours, and are highly adapted to open, frequently arid environments. This ground-dwelling lifestyle—spending the vast majority of their active time on the ground—is what has driven the evolution of their slender, agile physical form, enabling quick dashes between safe cover and foraging spots under the direct sun.
