A *Dry* Discussion About The Origin Of Bipedalism

Mclark,

I'm interested in this idea you've previously floated about the origin
of bipedalism being linked to arboreal origins. I know it's been
brought up usually in opposition to all that wet theorising, but I'd
like to hear you expound on your idea bit further. Care to have a
crack?
