is it not the case that most quad-peds are able to stand up almost immediately at birth?

maybe the truth is that our ancestors retreated to the canopy upon pregnancy, and spent much of the gestation process, including birth,up there. perhaps that is the reason that our babies crawl for the first months of their lives...

i'm left to wonder if allowing young children the opportunity to climb, rather than crawl, may have some psychological benefits.
