I'm not sure I understand your question. Are you asking if Lucy is still
considered a possible human ancestor, a part of the hominid lineage
leading to modern Homo sapiens? The "fossil record of human evolution"
encompasses all hominid lineages, including those which became extinct
such as the robust Australopithecines and Neanderthals.

"From Lucy to Language" by Don Johanson and Blake Edgar (Simon &
Schuster, 1996) is an excellent reference book documenting human
evolution from Ardipithecus ramidus to Australopithecus anamensis all
the way to anatomically modern humans. Along the way, you encounter a lot
more hominid species than I've been exposed to... Homo ergaster, Homo
rudolfensis, Homo heidelbergensis....
What I'd like to know is, how valid are these new species designations?
The discoverers of these specimens on the whole didn't assign them to the
names above... so how does one even go about "officially" changing the
designation if the original discoverers who published the finds are no
longer around? Or is it just "the consensus is" therefore that's what
we'll call it?
