This is sheer bad thinking. It's the best way to confuse the issue
thoroughly. Even IF it was true (and I'm pretty sure that the odds
against it are zillions to one) it's a bad way to try to sort the
problems out. I've never seen it before . . . . . . so I think we
can safely forget it . . . . . Phew!

It's one way to consider the matter. That's all. One way. You
should also try a few others: like "What special niche could the
protohominids have occupied?" or "What benefits could justify the
enormous costs of becoming secondarily altricial?" or "How could
these creatures survive without climbing trees at night?"

Why are these mundane questions ignored by the PA community? That
is what I find so deeply puzzling. Why do you all stick in that
ghastly rut of looking at how and when chimps or gibbons stand?
It's been worked to death. Ain't you got no imagination?
