IOW,
-Au.sedibae, like africanus & robustus, was a fossil relative of Pan,
-only incredible imbeciles believe they descend from sediba.

An updated analysis of hominin phylogeny with an emphasis
on re-evaluating the phylogenetic relationships of
Australopithecus sediba
Abstract
The discovery and description of Australopithecus sediba
has reignited the debate over the evolutionary history
of the australopiths and the genus Homo. It has been
suggested that A. sediba may be an ancestor of Homo
because it possesses a mosaic of derived Homo-like and
primitive australopith-like traits. However, an
alternative hypothesis proposes that the majority of
the purported Homo-like craniodental characters can be
attributed to the juvenile status of the type specimen,
MH1. We conducted an independent character assessment
of the craniodental morphology of A. sediba, with
particular emphasis on evaluating whether the ontogenetic
status of MH1 may have affected its purported Homo-like
characteristics. In doing so, we have also expanded
fossil hypodigms to incorporate the new Australopithecus
anamensis cranium from Woranso-Mille (MRD-VP-1/1), as
well as recently described Paranthropus robustus cranial
remains from Drimolen (DNH 7, DNH 155). Morphological
character data were analyzed using both standard
parsimony and Bayesian techniques. In addition, we
conducted a series of Bayesian analyses constrained to
evaluate the hypothesis that Australopithecus africanus
and A. sediba are sister taxa. Based on the results of
the parsimony and Bayesian analyses, we could not reject
the hypothesis that A. sediba shares its closest
phylogenetic affinities with the genus Homo. Therefore,
based on currently available craniodental evidence, we
conclude that A. sediba is plausibly the terminal end of
a lineage that shared a common ancestor with the earliest
representatives of Homo. We caution, however, that the
discovery of new A. sediba fossils preserving adult
cranial morphology or the inclusion of postcranial
characters may ultimately necessitate a re-evaluation of
this hypothesis.
cranial capacity is
small, but such a symplesiomorphic character doesn't make it closer to
Pan than to Homo.

:-DDD
Not me, but you no doubt!
Are these idiots really still too stupid to realize that the Homo-Pan LCA was no human & no ape???

It was an ape (hominoid), but neither chimpanzee nor human:

Yes, my boy, that was what I was saying, already in 1994 Hum.Evol.9:121-139. :-)

It's really not so difficult, even you can understand:
the LCA of today's hominids lived c 8 Ma in coastal forests along the (then incipient) Red Sea, wading bipedally, climbing arms overhead etc.
When the northern Rift (EARS) began to form c 8 Ma, different hominids began colonizing the Afar region:
Sahelanthr., Orrorin, Ardipith. & Praeanthr.(gorilla ancestors).
Homo-Pan remained in the Red Sea, until it opened into the Gulf
(Francesca Mansfield thinks this happened 5.33 Ma, caused by the Zanclean mega-flood):
-Pan went right -> E.Afr.coastal forests,
-Homo went left -> S.Asian coasts as far as Java & Flores.
If this it too difficult for you, google "human evolution Verhaegen" :-)

She tested 3 hypothesis: H1 (Proconsul is a stem catarrhine),
H2 (Proconsul is a hominoid), and H3 (Proconsul is a hominid), by
means of a phylogenetic analysis based on 816 cranial and postcranial characters, and found compelling support for a hominoid clade that
includes Proconsul.
So yes, Proconsul was a primitive ape (a stem hominoid), and a
generalized quadruped, not a aquarboreal biped.
