As a result, the rate of cultural evolution increased far more rapidly than the rate of human biological evolution. This dramatic change in the co-evolution process is known as “cultural takeoff.” How human language has evolved? Like other primates, our hominid ancestors must have first developed some call systems, in which calls were produced only when particular environmental stimuli were encountered.
