Darn good question.  Merecats also have a system very similar to that,
except with merecats, they only have 1 "lookout".

My guess is not all that complex -- heck, even honey bees have
"language" for describing locations and distances.

I haven't looked at anything about Neanderthals since college.

I don't think that's been explained to any degree that made any sense.
