These findings complement naturalistic observations in suggesting that chimpanzee tool-use is in some sense «culturally transmitted» — though perhaps not in the same sense as social-conventional behaviors for which precise copying of conspecifics is crucial.

It is concluded that both dolphins and sea lions can be taught to comprehend sentence-like instructions, and the simplified language learned by these marine mammals depends on the following learned cognitive skills.
From Animal Communication to Linguistics and Back : Insight from Combinatorial Abilities in Monkeys and Birds
Here, a twostep approach is adopted in order to discuss: what forms sound combination takes in animals, based on structural and functional criteria and when it may or not be appropriate to use linguistic terms; why sound combination may have evolved in some species more than others.
