New interpretation of Laetoli footprints using an experimental approach and
Procrustes analysis: Preliminary results
C Berge, X Penin & É Pellé 2005
C.R.Palevol.5:561-9
We compared Laetoli footprints (G1/35-36-37, G3/26) with modern humans (62
footprints), and a chimpanzee walking bipedally (5 footprints). Video
cameras allowed us to capture walking parameters on a wet clay walkway, and
the Procrustes method was used to analyze the footprint shape (outlines and
centres of pressure). Like humans, Laetoli hominids walked with small feet
gap, and probably low velocity (they used heels as brakes). They preserved
certain ape-like traits (foot proportions, roll-off). They also possessed
more marked human-like traits (small vault, metatarsal pressure, similar
toe-off). Like humans walking on a soft ground, they flexed toes at ground
contact, and then propelled themselves by pushing on the ball of the foot
and on digits (hallux and lateral toes acting together). The hypothesis of
permanently flexed, or curled-underneath, digits was not retained by
comparison with the chimpanzee.

Low velocity: clearly not savanna adapted...
