How do animals communicate?

Animals have various modes of communication that resemble language. These include vocalizations (like whale songs), gestural language (such as hand gestures), and body language (like aerial displays by birds). The brain regions controlling spoken language in humans are adjacent to those for gesturing, indicating an evolutionary relationship between speech and body movements. Some species, like non-human primates, are more advanced in gestural communication compared to vocal sounds. A notable example is Coco the gorilla, who learned sign language but couldn't produce vocal sounds, highlighting that some species have the motor pathways for advanced gestural communication but lack equivalent pathways for sound production 1.
