Babbling is NOT language but it is a "Species Specific" behavior which is a harbinger of its development.
All humans, regardless of race, culture or location begin to babble at around the same time of development. (Even deaf children begin to babble but quickly give it up and attend to a more rewarding though analogous activity using the hands).
I know of no other species that engage in babbling activity. As Eric Lenneberg would say, it is "Species Specific." It is combinative, because it involves the utterance of sound sequences.
It is here, however, that my analogy breaks down somewhat, because a change in the sound sequence of babbling does not to my knowledge indicate a change in meaning.
Babbling is, nevertheless, a sign, that a child is content for the time. It is a good activity for motor and auditory development.
