are distinguished primarily on two levels:
1. Brain Grows much anteroposterior length, the skull is long and narrow with a rounded forehead, a very marked occipital angulation with growth of very large nuchal muscle. Supraorbital torus more developed than in H. habilis fossils from Zhoukoudian finally have a greater expansion (average of 1300 cc.) and a more rounded skull on the back skull. Sagittal a chain is more marked due to the large muscle exercise for children. Thus H. sapiens described neurologically after the completion of cranial expansion.
2. Chewing: emphasize smaller molars (M3) by not grinding for teeth, zygomatic arches are weaker, and since 300,000 years ago, in Fangtian (China) is already the genetic absence of M3 (own sapiens) . The enlarged anterior dentition and supporting bone is pneumatized, so does 300-400000 year rise to the mouth of the neanthertales and retain some indigenous Australians.
erectus's face makes the iron bar pulling muscles of the temporal muscles grab objects by allowing the anterior dentition and that no cracks occur reinforces the orbital torus (argue things with his mouth without moving, just holding it and pulling her head back muscles being helped by nuchal and occipital base), you would use your mouth to hold food with their hands and manipulate ... This structure grows and develops erectus neanthertales. The femur has a coxal muscles associated with locomotion but very characteristic with a pillar on the posterior iliac wing, ischium has not fully rotated (yes in sapiens) with an anterior-posterior iliac spine. Have a more advanced level technical tools with increased impacts to make new tools.
