Answer

Brief Explanations:

Dolphins and bats both need to move in dark - like environments (bats in caves at night, dolphins in deep or murky water). Echolocation helps them navigate and find prey in such conditions. Sending sound waves is a means to achieve echolocation, not the root - cause trait. Communicating with other species through echolocation is not the main reason for its evolution.

Answer:

the need to move quickly through dark environments
