give me one evidence Lucy couldnot walk up right .
Her knee joint /jaws /half man ape structures.
Message 278I am saying that if australopithecus had an anatomical structure suitable for bipedal walking .Give me one evidence that it was ancestor of man.
Not sure where you are going with this, as you have barely stated a thesis for your argument.
If you want to discuss Lucy in specific, including the knee joints, jaw features (that are related to upright walking how?) and "half man ape" structures we have room on the
Lucy - fact or fraud? to discuss the features that are specific to Lucy.
As I recall it was the knee joint that showed she walked in a bipedal gait.
If you want to discuss that relationship of various hominid lines to the direct ancestry of
Homo sapiens that is a different matter.
If that gets too off-topic here and is not covered by any other topic we can always start a new one (the
idea being that the threads stay focused on specific topics for greater clarity ... the practice is frequently something else).
Welcome to the fray.
Enjoy.
