Yes, that's obvious: knuckle-walking is more derived than bipedalism: in
order to evolve from palm-walking (all primates incL.human infants, except
chimps & gorillas) to knuckle-walking (walking on the dorsal instead of on
the ventral side of the hand), chimps & gorillas needed an intermediary
phase where their hands were +-not used for pronograde locomotion. This
intermediary phase was not arm-hanging (alone): otherwise gibbons & orangs
would knuckle-walk on the ground, but they're palm-walkers. All apes still
walk regularly or occasionally on 2 legs, so the intermediary phase was
(short-legged) bipedalism (probably in combination with climbing arms
overhead).

Marc's explanation of how an obligate biped becomes a quadruped:
"why not move on 4 legs"

Yes, of course. Most mammals except humans & kangaroos move on 4 legs. I
guess there must be a good evolutionary reason for that.

Why don't you answer instead of producing empty blabla, my boy?

Because Doughboy, he is not the one proposing the radical hypothesis.

"he"=??- Hide quoted text -


He, yes. Actually anyone who doesn't subscribe to your off-beat
hypotheses. That of course means everyone.

Here is just a small list of "he" in the professional world, not
counting all those on this list.

Mario Vaneechoutte: "Verhaegen's reasoning was considered as
idiosyncratic by most of the participants."

"Prof. Tobias urged to state that the present-day fossil hominid
record consists of hundreds of different well-documented individuals
and that there is general agreement that australopithecines and Homo
have more in common than australopithecines and Pan/Gorilla."
