I have been following your colloquy on this N.G. for a coupleof
weeks. Fascinating!
What I missed --- much as one who came in during the second act of a play
--- is exactly what is the "power to weight ratio"? Is it:

1. Muscle power to muscle weight ie: fat content
2. Muscle power to skeletal weight. ie:attachment, mechanical
advantage from
3. Body power to brain weight. Gracile vs Robustus
4. Body weight to brain power. Concept vs Sence perception
5. Other ?

Lastly, may I suggest the event that led to the creation of the niche
that allowed,
even forced, the development of the bipedal hominids.--- The development
of the continental Rift ---- To the west,well watered and forested. To the
west, uplifted and arid. No proto-hominids to the west. No chimps or
gorillas to the east.
