If they'd endured as independent groups into the 21st century without being colonised by Europeans, as the map shows, they would almost certainly have developed defined borders.

Why? Europe had firm (occasionally changing) boarders for centuries before the sixteenth century, do you think they were simply behind on an inevitable development or that contact with the rest of the world would necessitate their development?

I think it's interesting to try and imagine situations where firm boarders aren't established. In such a situation it's interesting to consider what rules could or would exist regarding immigration and outsider communities.
