so what are you trying to say that lucy was bipedal
No, I'm not. I'm saying that your source is demonstratably wrong about the pelvis of Australopithecus being more similar to an orangutan than it is to a human.
I think we both agree that Lucy in herself, was not a fraud like Piltdown man was. As such posting in this thread is not on topic, unless you are suggesting that fraud has taken place somewhere.
Because all the evidences I wrote
The bipediality of Lucy and her kin is irrelevant to my life, but I find the topic of interest for debate. How about you propose a new topic on the subject. We should probably focus on contemporary evidence where possible. How about it?
