African elephants flap their large years to cool off what biology theme does this phenomenon represent?

The phenomenon of African elephants flapping their large ears to cool off represents the Biology theme of adaptation. This behavior illustrates how the elephants have evolved physical traits, such as large ears with a high density of blood vessels, to regulate their body temperature in hot environments. It highlights the interplay between morphology and environmental challenges, demonstrating how animals develop specific features to enhance their survival.
