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.
According to "Homo erectus – The First Humans”, what are the different hypotheses that might explain the stature of Homo floresiensis?
A.Island Dwarfism
B.They might be descended from Homo habilis or an Australopithecine
C.All the individuals had a genetic mutation
D.Both A and B
1). There is quite a bit of variation in fossils attributed to the species Homo habilis. Some of the fossils have larger brains (750cc) and flat, wide faces. If separated out from Homo habilis, these fossils would be placed in the genus and species called ................
