6) bipedalism & early hominins, Describe what you learned about Australopithecus afarensis: like the dates, locations, morphology, and what we can tell about their behaviors from the fossil evidence that we have.

DO NOT USE ANY OUTSIDE SOURCES FROM THE INTERNET, ONLY USE THE SOUCES, AND THE INFORMATION THAT I GIVE YOU.

6) Use the 9 steps of evolution (I included a picture) to organize your answer and explain the transition from the LCA
quadrupedal forest ape to the very first bipedal hominins 6 million years ago. Start with one of the specific
morphological changes needed for bipedalism, combined with the relevant selection pressures & the potential
benefits of bipedalism, to explain each of the 9 steps to show the full process of how bipedalism evolved. Use
information from the readings to fully explain and help support the steps from lecture.

7) Describe what you learned about Ardipithecus ramidus: like the dates, locations, morphology, and what we
can tell about their behaviors from the fossil evidence that we have. When discussing their bodies, make sure
you explain why some researchers think A. ramidus was may have been bipedal, but other are not as sure.

sure you explain how we know that A. afarensis was bipedal.
