What are postcranial features?
What are postcranial features?
The postcranial skeleton includes all the bones and cartilages caudal to the head skeleton; it is subdivided into axial components (the vertebral column, ribs, and sternebrae, which are “on” the midline) and appendicular components (the forelimbs, hindlimbs, and pectoral and pelvic girdles, which are “off” the midline) …
What are the characteristics of Neanderthals?
Neanderthals had strong, muscular bodies, and wide hips and shoulders. Adults grew to about 1.50-1.75m tall and weighed about 64-82kg.

What are the characteristic features of archaic humans?
Archaic humans differed from modern humans mainly in the features of the head. Unlike modern humans, they had a backward-sloping forehead, big brow ridges, and a low, elongated skull. Their brain size, however, was close to that of modern humans.

The adult human skull is comprised of twenty-two bones which are divided into two parts of differing embryological origin: the neurocranium and the viscerocranium.
What is middle Pleistocene humans morphology?
Neanderthals and modern humans exhibit distinct facial architectures. The patterning of facial morphology of their predecessors, the Middle Pleistocene humans, is more mosaic showing a mix of archaic and modern morphologies. We show that facial features can be used to separate Pleistocene humans into temporal clusters.
What traits do modern humans have?
Modern humans have a number of anatomical characteristics that distinguish them from premodern humans. These include a small face, small jaws, small teeth, a vertical and high forehead, a narrow nasal aperture, a narrow body trunk, and long legs.
