I admit that wormholes are iffy, but given wormholes, I don't think
most places could stay very isolated. They'd have to destroy *all*
holes to their region, and then these holes could be rebuilt again
very quickly from the "upwind" direction (from where each civilization
began). Hopes for cultural diversity would have to be based on
something other than isolation.
