seriously this is why we evolutionists always get so irate when people say the flaws of evolution should be taught, because we know that 9 times out of 10 they are refering to flaws that are not even true.
Lucy's knee joint (ie the true story): http://www.talkorigins.org/faqs/knee-joint.html
Leakey even said in 1983 that no firm conclusion could be drawn about what species Lucy belonged to.
What did he apparently say, and where did he say it. It's no use for these websites to make up these claims without reference. It is likely BS. The consensus is that it is Australopithecus afarensis (and other fossils of this species are known)
They are also typically selected about what research they mention: http://www.talkorigins.org/faqs/homs/a_piths.html
Sorry, I can't find any recent articles that still suggest that Lucy is the missing link. I did find this article which I do not believe are those crazy creationists.

Here's the notable quote.
Most hominid fossils, including the two discussed by MOM (Lucy and Java Man), have never been claimed to be the "missing link" in the sense of a common ancestor of apes and humans.
Sorry, this looks very Clintonian. "What is the meaning of is?". Anyway, I can find very few articles recently that are still pushing Lucy. Maybe you can. I did find this article debunking Lucy, but not sure if you care to read.

Notable quote:
LUCY Present-day speculation about human evolution revolves about a group of fossils called australopithecines and, in particular, a specimen called Lucy, a 40% complete skeleton. Lucy was discovered by D. C. Johanson in the Afar area of Ethopia during investigations conducted from 1972-1977. In a National Geographic article (December 1976) Johanson claimed that: "The angle of the thigh bone and the flattened surface at its knee joint end...proved she walked on two legs." However, the knee joint end of the femur was severely crushed; therefore, Johanson's conclusion is pure speculation. Anatomist Charles Oxnard, using a computer technique for analysis of skeletal relationships, has concluded that the australopithecines did not walk upright, at least not in the same manner as humans. In this connection, it should be mentioned that the chimpanzee spends a considerable amount of time walking upright. Thus, there is no scientific basis for a conclusiion of bipedalism in Lucy. Lucy and her relatives are probably just varieties of apes. Finally, there is evidence that people walked upright before the time of Lucy. This would include the Kanapoi hominid and Castenedolo Man. Obviously if people walked upright before the time of Lucy, then she must be disqualified as an evolutionary ancestor.
