I don't believe she gave up tree life to walk around all the time,
Her
ancestors did that. She bears the hallmarks of a somewhat arboreal life, but other hominid species, such as
A. africanus, show these hallmarks more strongly. That is,
A. africanus was more arboreal than
A. aferensis.
and evidence points to her being a knuckle walker too.
Err... no, it doesn't. I've already cited many papers and articles showing that
A. afarensis was bipedal, and you already agreed to this.
So she MAY have been capable of walking but probably not.
Err... except numerous studies and analyses have shown that
A. afarensis was bipedal for at least the large majority of its locomotion, if not the entireity.
(only capable of walking if the 40 pieces of her left pelvis was assembled correctly- which is biased and doubtful).
Err... except I've cited numerous
other examples of fossilised members of
A. afarensis which have an intact pelvis, so we can directly gauge the accuracy of the reconstruction. And, lo and behold, it's accurate.
I want to see more fossils of Lucy other than the pelvis johanson found, just one specimen is hardly proof of a full time walker.
Err... you know 'Lucy' refers to a single individual, right?

There's no more fossils of her, because there's only
one Lucy.
But Even if she could walk around she was capable of climbing and knuckle walking ...So if she walked around it would have been a third of the time or less.
No. As I've repeatedly stated, and repeatedly substantiated,
A. afarensis' skeletal structure (foot, pelvis, knees, torso, etc) all point to a primarily
bipedal locomotion. Lucy undoubtedly could climb trees, as modern humans can, but she, like us, was primarily bipedal.
Secondly, The point is that many chimps have similar knee characteristics so what does it make Lucy if she has them?
Can you cite a source for this information? How similar is similar?
Plus Several non-archosaurian lizard species move bipedally when running, usually to escape from threats. So what does it make lucy if she could stand up? I mean even birds hop on two legs. The matching of bipedalism and humans is a faulty argument. Even if it were true and that is a long shot.
Err... you realise that it's
your argument, not ours, right? You're the one trying to prove that she was quadrepedal and therefore a chimpanzee, remember? We have found many hominid species, some quadrepedal, some bipedal.
A. afarensis happened to be bipedal.
You are the one insisting that she's not bipedal, while simultaneously claiming that she's an ape, a chimpanzee, and a human. You don't seem all that sure of what you think she is.
thirdly, as far as the foot bone being non human, there is no evidence that the bone matches any known ape or monkey like creature this would be the first. So how do you know for a fact it isn't actually human?
Because we can compare the metatarsal with the human analogue, and directly observe that, in fact, the foot of
A. afarensis is not the foot of
H. sapiens. People who specialise in skeletons and bones aren't iditios, gradyll. You'd be blown away by what they can deduce from bones - age, gender, diet, gait, locomotion, and, yes, species.
Even if it is a lucy bone, you couldn't prove it with just one, you would need two at least. Because someone could always say it's human.
Err... no. We can determine which species a fossil is from by more than just direct comparison (ironically, the method you propose here is in direct contradiction to one you propose later on in your post, namely that the fossils are that of a human foot).
It came from the same geologic layer as the layer containing some human footprints as well. (but that is debatable Re:Laetoli Footprints). The main point being that no full specimen of lucy or lucy's family has ever been fitted with a metatarsal like the one in question. No feet to compare it to, no other specimen. The only reason why they believe it was lucy's is because humans hadn't evolved yet. Couldn't there be another problem? Like that macroevolution is faulty?
No, and frankly your reaching. As I said before, and as my citations explicitly stated before, and in yet more sources like
here and
here - the bones are of
A. afarensis. And even if all the evidence was wrong and the bones
weren't of
A. afarensis, you're let with the very conspicous problem of
another species of bipedal hominid that lived exactly the same time as
A. afarensis, yet further bolstering the argument that the modern human species is descended from ancestral species that lived orders of hundreds of thousands of years ago.
look for yourself, lucy's foot is just another human foot.
see any similiarities?
Lucy's Foot
Human Foot
No, I don't. I see distinct markers that distinguish the human metatarsal from that of
A. afarensis. if nothing else, the bone of the adult
A. afarensis is far smaller than that of the adult
H. sapiens.
