The trait called "the H-O mandibular foramen" is

What dating technique was used to date recently discovered SE Asian Homo erectus fossils and why is this controversial?

Relative to evidence for speech, the shape of the basiocranium substitutes for the biological trait of

All archaic Homo sapiens (early and late) have a cranial capacity at least as large as 1200 cc.

Describe Homo erectus from the neck up, commenting on the changes in its general anatomy from the australopithecine grade.

The first early archaic Homo sapiens reported to show any sign of early Neandertal tendencies is

You would find the saggital keel on a Homo erectus skull

Experts point to encephalization as the single most important factor characterizing the evolution of the genus Homo.

The biggest difference between archaic and AMH are high foreheads, rounded heads, and

Just because Neandertal might not have been able to use the vowels "a" and "i" does not mean their speech was inferior to that of AMH.

You would characterize Neandertal crania as having all of the following traits EXCEPT

Discuss the Assimilation model, pointing to similarities and differences to the two "extreme" models.

Anthropologists define speech as sound-based language.

Since chimpanzees can be taught to speak simple words, scientists conclude that speech was evident in the Last Common Ancestor of chimpanzees and humans.

What is unique about the Sinanthropus pekinensis fossils themselves?

Discuss the hypotheses concerning what happened to Neandertal.

It is not likely that Neandertal evolved directly into AMH becuse their dates overlap too much.

Describe the early archaic Homo sapiens grade as they appear transitional between Homo erectus and AMH.

Compare Neandertals and AMH postcranially and you would find Neandertal shows all of the following traits EXCEPT
