Students have asked these similar questions
Identify whether the evolution of the hominins support a scenario of slow, incremental change or punctuated equilibrium and explain why.
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?
