The usual just-so, unscientific, outdated afro+anthropocentric savanna fantasies ("gorilla+chimp=forest=quadrupedal, but human ancestors ->savanna ->bipedal") are contradicted by e.g.
- shell engravings, made by H.erectus, google "Joordens Munro": no seashells in any savanna,
- stone tools, used by archaic Homo,
- Pleistocene island colonisations (Flores >18 km oversea),
- Homo's huge brain (DHA etc.), cf. sea-otter brain > river-otter > weasel,
- Pleistocene intercontinental dispersal: Java, Europe, Africa,
- pachy-osteo-sclerosis in archaic Homo is *exclusively* seen in slow+shallow-diving tetrapods,
- etc.etc.:
human physiology & anatomy leave 0 doubt that our ancestors regularly dived, most likely often for shellfish, probably maximally early-Pleistocene,
google e.g. "coastal dispersal Pleistocene Homo"
or "GondwanaTalks Verhaegen English".

I think a major part of this is the failure -- sheer reluctance -- to define "We," what we mean when we say "Our Origins."

Is the first of our line the first ape? What led to apes? The first bipedal ancestor? The first to make tools?

For a VERY long time already, starting before I incorporated many of
my present ideas into my model, I tended to think of "Our" line, the
"Homo" line as best being characterized by bipedal locomotion.

What truly sets us apart from Chimpanzees and Gorillas, and the further
back we're looking the more important this is, is the fact that we are
bipedal and they are not.

THEY branched off from US.

The ancestor of the Chimp was very clearly bipedal, the ancestor of the
Gorilla was all but completely certain to have been bipedal.

They split away from US, not the other way around.

They evolved from US.

Homo (vs Pan).

Is the first of our line the first ape? What led to apes? The first bipedal ancestor? The first to make tools?

Early-Miocene(!) Hominoidea were already bipedal waders-climbers in swamp forests,
google "aquarboreal":
humans & hylobatids are still BP, but
- Pongo (orangs) evolved from this into "fist-walking",
- Pan & Gorilla into (+-different sorts of) knuckle-walking.

For a VERY long time already, starting before I incorporated many of
my present ideas into my model, I tended to think of "Our" line, the
"Homo" line as best being characterized by bipedal locomotion.

In a sense, partly, yes:
JTEM, why don't you google "aquarboreal"??
