Students have asked these similar questions
Which hominins might be ancestral to us choose one that you find especially interesting (except H. sapiens) and explain how it fits into the picture of the Hominin family?
What is the difference between a "derived"
versus a “primitive" trait? Give an example
of both, seen in Au. afarensis.
Which of the paleoenvironment hypotheses
have been used to describe early hominin
diversity, and which have been used to
describe bipedalism?
Which anatomical features for bipedalism
do we see in early hominins? Are these
primarily obligate bipeds? Explain.
Describe the dentition of gracile and robust
australopithecines. What might these tell us
about their relative diets?
List the hominin species argued to be
associated with stone tool technologies. Are
you convinced of these associations?
Why/why not?
Where on this cladogram would the derived trait of using their front teeth as a “third hand” be placed? This a trait exhibited by Neanderthals.

A bushy interpretation of evolution suggests multiple overlapping species of hominins, with some species short-lived, and others existing for a long period of time.

- Paleoanthropologists generally agree that Homo erectus belongs in our genus and represents a significant shift towards adaptations important to our own species. However, there is much variation among specimens that are grouped into H. erectus. Your instructor will let you know which of these fossil representatives to use for the exercise today.Based on your measurements and comparisons in the table above, what are major differences among Au. africanus, H. habilis, and H. erectus? Do you think H. habilis is more like Australopithecus or Homo? How do these three species reflect the major environmental pressures of the time periods in which they lived, respectively? List three features that are changing in the genus Homo due to these selective pressures. List three features found in H. erectus that are derived, compared to Au. africanus.arrow_forwardWhich of the following is responsible for the early predominant image of Neanderthals as brutish cavemen? a). They had small brain cases with stocky bodies and were always recovered from cave sites b). The fossil evidence reveals that they had little cognitive capacity and had a hunched over posture c).
