Vocalization and Callback (AUDIO)
Caption
The researchers recorded the vocalizations of individual lemurs and played them back to the group. Only lemurs that shared a close grooming relationship with the individual emitting the call responded, even if the lemur making the vocalization was not nearby. In this recording, a female lemur calls out and three close relations respond.
