So then, why all these advanced brain systems, languages etc? If an amoeba can do the same thing it would seem a bit of a waste of time. But I suppose it depends on what you mean by 'conceptual'. I'd say conceptual requires a structured symbolic language, which animals don't posses.
1) why would it be a "waste of time" ? 2) Im a bit confused on how you can confuse an amoeba with an animal. After all, we were talking about animals having a "conceptual mind", right? HTML:
