One importance for finds in this era is that we now know the Australopithecus gens were tool users.  Complex tool use and cooperative hunting are the chicken and egg of human evolution - at some point evolution either suited our line to hunting, or in some way hunting caused our line to evolve.  We have so few data points of these creatures, unlike later homo species, that any discovery in this area is important.
