What if, by "object", we mean not a specific instance of an object, but rather the whole category of objects? Do penguins or other animals link a specific vocal sound to "shell" or "children" or "nest"?
Dogs can definitely do that: teach a dog the meaning of 'ball' and some will then apply that to any round object that behaves more or less like the balls they're used to.
