Environmental familiarity can be a huge thing. It's something we don't really notice with our mix of technology and associated wide-ranging logistics.

I've got a little taste of it myself. I casually hiked and camped in the Northern Rockies for years. I didn't realize how many small bits of specific knowledge I'd picked up until recently moving to the midwest and doing some camping here. Different woods, that burn differerently. Damper conditions in general that make for all kinds of different prep. My knowledge of what is safe to eat (and what is not) went from fairly extensive to almost nothing. Different geography and climate that changes what you want in a campsite and what sort of site you are likely to find. A thousand little things that each make a difference. With only stone age kit and knowledge base, moving out of your "home range" would have doubtless been quite challenging.
