Have We Been Barking up the Wrong Ancestral Tree?
Australopithecines Are Probably Not Our Ancestors

And then you would expect a phylogenetic analysis comparable in quality
to these:

https://doi.org/10.1016/j.jhevol.2019.03.006
https://doi.org/10.1016/j.jhevol.2022.103311
But no, these studies are not even mentioned in your letter.
Yes, AFAICS, they confirm what we're saying.
Then why does your letter not mention them?
That would have been great support.
But in fact these studies refute your hypothesis, because they show that apiths are the sistertaxon of Homo, to the exclusion of Pan and Gorilla.
The fact that you do not mention these studies is a glaring omission that makes your letter totally irrelevant with regard to hominid phylogenetics.
He didn't even look at them. In the abstracts alone:
https://www.sciencedirect.com/science/article/abs/pii/S0047248404001277 Inferring hominoid and early hominid phylogeny
using craniodental characters: the role of
fossil taxa
December 2004
"Regarding early hominids, the relationships of
Sahelanthropus tchadensis and Ardipithecus ramidus
were relatively unstable. However, there is
tentative support for the hypotheses that S.
tchadensis is the sister taxon of all other
hominids. There is support for the hypothesis that
A. anamensis is the sister taxon of all hominids
except S. tchadensis and Ar. ramidus. There is no
compelling support for the hypothesis that
Kenyanthropus platyops shares especially close
affinities with Homo rudolfensis. Rather, K.
platyops is nested within the Homo + Paranthropus
+ Australopithecus africanus clade. If K. platyops
is a valid species, these relationships suggest
that Homo and Paranthropus are likely to have
diverged from other hominids much earlier than
previously supposed. There is no support for the
hypothesis that A. garhi is either the sister
taxon or direct ancestor of the genus Homo.
Phylogenetic relationships indicate that
Australopithecus is paraphyletic. Thus, A.
anamensis and A. garhi should be allocated to
new genera."

phylogenetic stability of Ardipithecus
ramidus as a basal hominin
June 2019
" Despite the new data and matrix revisions,
tree topology has remained remarkably stable.
The addition of new craniodental material has
served to markedly strengthen the support for
the placement of Ar. ramidus as being derived
relative to Sahelanthropus, and as the sister
taxon of all later hominins. These findings
support the phylogenetic hypothesis originally
proposed by White and colleagues in 1994."

An updated analysis of hominin phylogeny with
an emphasis on re-evaluating the phylogenetic
relationships of Australopithecus sediba
February 2023
"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."
As such it's worthless.
No wonder you couldn't get it published in JHE.
Yes, like you, JHE still lives in the Middle Ages... :-D
I'm afraid that your letter is destined for oblivion.
