Vedclass · Answer

(D) According to $Allen's$ rule,animals living in colder climates generally have shorter ears,tails,and other extremities compared to those living in warmer climates. This adaptation helps in minimizing heat loss from the body surface in cold environments. Conversely,animals in warmer regions possess larger pinnae (ears) to facilitate greater heat dissipation,helping them maintain body temperature. Therefore,the large size of pinnae in warm-region animals is an application of $Allen's$ rule.
