 The finding was particularly promising because it potentially revealed a previously unknown transitional species between the more ape-like australopithecines and the more human-like "Homo habilis".Berger claimed that this new finding represented "the most probable ancestor" of modern-day "Homo sapiens".Berger's work at the Malapa site was significant not only because of the discovery itself, but also because of the way he and his collaborators shared information about their findings.
