resource transport"
Review: EE Sarmiento 2006 AJPA 130:142-3

"... Meldrum demonstrates that trackways through volc.ash differ markedly
from the Laetoli prints, esp.in the consistency from one print to the other
present in humans, but absent in Laetoli. G.Berillon concurs, finding
corroborative evidence in laetoli forthe abducted hallux & actively
(muscularly) supported pedal arch suggested by the Hadar remains. P.Schmid's
analysis of laetoli additionally indicates that the printmakers lack the
trunk rotation ass.x modern hman bipedality.
....early Homo & its precursors probably lacked the stiff-legged gait of
modern hmuan bipeds. Fixed pedal arches & nearly extended knee-joint
position were probably a rel.much more recent phenomenon in human evolution.
.... AL 2888-1's iliac orientation, & femoral & tibial torsion indicate that
its lower limb segment movements during bipedal walkingdid not coincided
with the plane of forward motion, questioning the relevance of a humanlike
pendular model.
.... Entertaining a KWing stage in human ancestry ... D.Begun follow Washburn
& ultimately Lamarck in clining to misconceptions that Afr.apes embody the
primitive & humans the derived. ..."
