Stuff like that it had a foot that had a very opposable "thumb" for use in trees, IIRC even more so than the chimps, but it still managed to be ok for bipedal walk. It's as if evolution first tried to produce a better hybrid, before giving up entirely on the idea of living in trees.
ETA: but when you factor in that where they discovered it there used to be a forest at the time, I guess it's not very surprising that it was still an advantage to be able to live in trees.
There is every reason to think Lucy and her Australopithecines could hightail it up trees when necessary. All this can tell us is that Ardi and those hominids earlier than her (that we havent found yet but they must have existed) had the propensity to walk upright when it suited them. It about the only way we can distinguish an early Hominid from a Proto-chimp.
