Can you have communication without culture? For instance, dolphins can be taught to run a maze that other dolphins can't solve immediately. Put a taught dolphin in the tank with a novice, and the novice can then run the maze, first time. So they DO have communication. And it takes several to mate with one female because some have to hold her in position (gang rape as a way of procreation?) But they don't have artifacts - do they have lifestyles? This is a fun thread!
