or the Human were Grouped in Small Groups (families?) at that time, and these small groups were obliged to cooperate anong them in hunting and not only due to some restrictive conditions....but they were separated but huge distances --in large steppes...so in order to initiate contacts ,to can organize the hunting, to signal the ennemies, to meet for mating, they needed to generate a complex vocalisation system to be used across large distances...
