Laetoli footprints

[Marc Verha]

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.

Wonder why they didn't use 62 gorilla footprints? Guess they
hadn't heard of Marc Verhaegen.

First sensible talk since years, Olson... :-D

Man, do you really have to open your big mouth to produce such
blabla? Why not simply read the abstract without producing
irrelevant foolish commments?? You're a real idiot, Olson,
"the" example of a savanna believer.

Of course, everyone except Verhaegen knows why they

Human like: Like humans, Laetoli hominids walked with
small feet gap, and probably low velocity (they used heels
as brakes)

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 ofpermanently flexed, or curled-underneath,
digits was not retained by comparison with the chimpanzee.

Chimp like They preserved certain ape-like traits (foot
proportions, roll-off).

Conclusion: more human like.

Low velocity: clearly not savanna adapted...

ROFL

If you use that logic, neither are tortoises found on the
savanna. How about the *ROCK* python found at Laetoli, not
much velocity there either. Does it take velocity to be
savanna adapted? Go back to school Verhaegin.

Not a problem.

What's the matter Marc? This was YOUR cite. Suddenly it's not
so acceptable for you?

Material restored: Human like: Like humans, Laetoli hominids
walked with small feet gap, and probably low velocity (they
used heels as brakes)

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 ofpermanently flexed, or
curled-underneath, digits was not retained by comparison
with the chimpanzee.

Chimp like They preserved certain ape-like traits (foot
proportions, roll-off).

Conclusion: more human like.

Ah, so that's why you no longer like the cite...
