I like to point out that, given the present nomenclature where humans are
apes, we need to always refer to Chimps as humans seeing how they
evolved from upright walking ancestors who in all probability used tools
in a way people only pretend that Chimps do.

Put short: Chimps arose FROM our line, not the other way around.

And when we talk about bipedalism in paleo terms, we're really talking
about changes to the anatomy such as placement of the foramen
magnum, which has to move towards the center of the skull to be held
upright, but is further back on chimps than we find on any candidate
for a Chimpanzee ancestor.

Chimps can stand on their legs. Chimps can even walk upright. But, the
foramen magnum is still located much closer to the back of the skull than
found on humans and it's own distant ancestors. It's clearly NOT a bipedal species. It has evolved AWAY from bipedal locomotion and to knuckle
walking.

All apes had vertical ancestors, google our TREE paper "aquarboreal apes".

No: both Pan & Homo evolved from aquarboreal (stone-tool-using?) ancestors.

Neandertals had the For.M more dorsally than we have:
our fully upright wading-walking locomotion is only late-Pleistocene?

Yes, that's what we're saying for ages, google our TREE paper "aquarboreal apes"..
KWing evolved in parallel in Gorilla//Pan.

From FRONT to center, yes, but not from the back.

:-D
Don't you understand "dorsal"?

Dude, *Way* ahead of you here. My point wasn't that there's anything unique about Chimps, it was about the nomenclature.

No. Pan might not even exist outside of a popular grouping.

There's a legitimate argument to be made to do away with Pan, group
them under Homo. A different SPECIES of Homo but still Homo.

Neandertals had the For.M more dorsally than we have:

From FRONT to center, yes, but not from the back. But, interestingly, I have pointed out in the past that Neanderthal anatomy is far better suited for climbing than is our own. And that ambush hunting is not only plausible
but would explain why throwing spears appear to vanish from the
archeological record for 200 to 300 thousand years.

our fully upright wading-walking locomotion is only late-Pleistocene?

Humans were even less of "A" thing back then than they are today. They
were ethnic/racial divergence gone wild, by our standards, different populations adapting to different environments.

Modern humans are a hybrid,

Which is not accurate from the standard use of the word.

It is.

The foreman magnum on a Neanderthal isn't closer to the
back of the skull, it's further away from the front. This is
very different from the movement we see in Chimps where
the foreman magnum is a good deal closer to the back
than is found on humans or their own ancestors.
