How did large ears first appear on an elephant?

Large ears in elephants are believed to have evolved as an adaptation to their environment, particularly in hot climates. The large surface area of the ears helps dissipate heat, allowing elephants to regulate their body temperature more effectively. Additionally, the ears serve as a means of communication, enhancing their ability to hear and be heard over long distances. This combination of thermal regulation and social interaction likely drove the evolutionary development of their distinctive ear size.
