Traditional PA reasoning:
- Gorilla & Pan = Africa, hence Homo also = Africa
- we had chimp/bonobo-like ancestors
- quadruped primates = forest, humans live outside forest:
- leaving Afr.forest = entering savanna -> bipedal

All these preassumptions happen to be wrong:
- Gorilla+HP ancestors lived in Red Sea forests
- bipedalism is much older than "hominin", google "aquarboreal"
- Pan also evolved after the H/P split
- Pliocene Homo = S.Asia: no Afr.retrovirus DNA

The problem here is that they are seeing the knuckle walkers
as the basal form, when we know it's the other way around:

Chimps are definitely (and Gorillas are more than likely)
secondarily knuckle walkers. Their ancestors were bipedal.
And the human hand is the less derived. once someone
grasps this they see everything flowing in the OPPOSITE
direction -- from East to West.

Their ancestors radiated out, pushing away from the east
coast of Africa, becoming more & more "Ape" the further
they got (and the less genetic influx they saw) from the
parent Aquatic Ape population.

Where bipedalism and Aquatic Ape began I do not know,
and it really isn't that important to me. Someone wants
to say Europe or the Mediterranean? That's fine with me.
What is important, as I see it, is the Asian coastline and
down into the Horn of Africa. Once they got there the
genus was safe. They could wander the sea side, occupy
environments from equatorial to sub tropical. This would
assure that SOME groups would survive matter what
nature threw at them.

A super volcano, for example, could cast the entire planet
into a "Volcanic Winter." This would be prolonged and
catastrophic in the northern hemisphere, while with its
duration and magnitude lessened near the equator...

Chimps evolved FROM this Aquatic Ape population. We
did not evolve from Chimps, they evolved from us.

We likely created them. Their ancestors likely spanned
the distance between east and west Africa, until our
ancestors, the line they split from, later drove them to
extinction everywhere but more distant forests.
