I hesitated whether this should go here or in the Biology section, but finally, here I go.
Let's imagine that some of our evolutionary close relatives, I mean much closer than the chimps or gorillas, is found living on a remote island or deep in some jungle. Say, the Neanderthals or the recently discovered "Hobbits".
Folks speaking a language of, say, 200 words, capable of counting to 7 and handling tools with up to 3 distinguishable parts. Living in a social structure somewhere between a pack of gorillas and a Stone Age tribe.
What would their legal, moral and political status be? Would we know how to coexist with being that are more than animals, but not quite humans like ourselves?
Just curious....
