Risk Minimization and a Late Holocene Increase in Mobility at Roonka Flat, South Australia: An Analysis of Lower Limb Bone Diaphyseal Shape.

These data are consistent with the risk minimization model, indicating that South Australians became more mobile post-ENSO to better exploit a less productive environment by expanding their foraging radii. The temporal shift toward more elliptical diaphyses is more notable in females than males, which is consistent with Aboriginal ethnographies that show both sexes being intensely involved in hunting and capturing game animals.
