I've seen a few claims of like this, and it always confuses the hell out of me. Of course they'd have a sense of property or territory, it might be very different to how for example, an English court may view land but that does not make it any less valid (which didn't tend to matter really). Not to mention it's lumping together a diverse groups of peoples,many of whom would not even know of the existence of some of the other groups in this homogenous category they've been lumped in with.

Regardless, here's a few threads that might interest you while a more up to date answer can be written up.
