I have just found this article that is in line with my above model:
---------------------------------------------------------------------
http://www.biology-online.org/articles/elephants_imitate_sounds_form.html

"It is exciting to see that African savannah elephants follow a pattern we've seen in other terrestrial and aquatic species capable of vocal learning, "Tyack said. "Vocal learning should also occur in other species where long-lived social bonds are based on individual relationships and
=====================================================================
"where members of a group separate and reunite over time."
=====================================================================

SO WHERE THE HUMAN FAMILY OF THAT TIMES
-- separate (on the Family Territorial Areal)
and
-- reunite (during the hunting and to fight against natural enemies) over time
