Several important theories on speech include one theory that language evolved from work chants and grunts, which were already rhythmic, thus could have been the ancestor of poetry!. also, another theory was that language came from noises that humans made to attract mates from the other gender!. Dirty limericks evolved rather recently!.Www@QuestionHome@Com
