Many modern humans would travel for no good reason on a moment's notice. Ofcourse here are talking about our greater family tree and its entirely possible that more confined lifestyles (like e.g. the great apes of today) where more typical earlier on. I would think though bipetalism did not get selected just to increase the daily range from the home base. At some point some hominid species started roaming and reasons to do so would be abundand (overpopulation, drought, following animal migrations etc). The trouble is (starting already with archeology) that the stuff that survives the aeons to be found today is always "special" in some way. Like being burried in certain conditions, being in a collapsed cave etc. Nature is a great recycler and doesnt leave many traces of its pathways.
