Question: What can we conclude about the Herto skulls from Ethiopia?

Scientists have unearthed in Ethiopia three 160,000-year-old skulls that they say are the oldest near-modern humans on record. Telltale marks on the bones suggest that the hominids engaged in mortuary rituals. The fossils are described in two reports published today in the journal Nature.

What do traits of anatomically modern humans include?

Anatomically, modern humans can generally be characterized by the lighter build of their skeletons compared to earlier humans. Modern humans have very large brains, which vary in size from population to population and between males and females, but the average size is approximately 1300 cubic centimeters.

What do Neandertals cold-adapted traits include?

Neanderthals were a coldadapted people. As with their facial features, Neanderthals‘ body proportions were variable. However, in general, they possessed relatively short lower limb extremities, compared with their upper arms and legs, and a broad chest. Their arms and legs must have been massive and heavily muscled.

A team of French and American archaeologists has found clear evidence of cannibalism at a 100,000-year-old Neanderthal cave site in southern France. “This is conclusive evidence that at least some Neanderthals practiced cannibalism,” said paleontologist Tim White, professor of integrative biology.
