In particular, H. erectus had

  1. relatively elongated legs
  2. shorter arms
  3. similar torso proportions to those seen in modern humans.

This suggests it had adapted to walking on two feet in a more open, grassland environment, rather than swinging from tree branch to branch. Unlike Australopithecus fossils, Homo erectus fossils don't preserve features related to climbing.

Apes characteristics shared with H. erectus

  • Dental development is similar to primates (molar teeth had large roots but were decreasing toward a more modern size)
  • the skulls of Homo erectus were quite different to those of modern humans (jaw was large and thick without a pointed chin)
  • the body (known only from the Chinese specimens) tended to be shorter and stockier than those of modern humans and similar with apes stature
