"The joints and movement are different... we don't spend much time swinging from trees"

Definitely. When you no longer rely on keen upper-body strength (specifically in the arms and shoulders), and instead utilize lower appendages for impetus, much of the body changes shape. Truly interesting!

Of course, we could all be very wrong, but supposing that we aren't, I think that a model like this (especially how you have described it, Carolly) could be fascinating!

I just adore these mystery models! We so rarely get a chance to offer ideas based on enigmatic words and phrases.

Anyway, even though I know none of this is done for me, I want to personally thank all of you for the input! This is great stuff!
