There's a difference between having the concept of number and reacting to quantities or having expectations that are unmet. There is no need for abstract concepts. All animals (in the phylogenetic sense) other than ourselves perceive reality utterly concretely. I am not sure how these brain scans are supposed to really show otherwise. Show me an animal that can describe and argue and you will have my attention. For now, I only see signalling and expression, but no language showing signs of description and argumentation.
