Homo Erectus - Use of Tools

Use of Tools

Homo ergaster used more diverse and sophisticated stone tools than its predecessors: H. erectus, however, used comparatively primitive tools. This is possibly because H. ergaster first used tools of Oldowan technology and later progressed to the Acheulean: while the use of Acheulean tools began ca. 1.8 million years ago, the line of H. erectus diverged some 200,000 years before the general innovation of Acheulean technology. Thus the Asian migratory descendants of H. ergaster made no use of any Acheulean technology. In addition, it has been suggested that H. erectus may have been the first hominid to use rafts to travel over oceans.
