>Scientists have long claimed that our ability with numbers is indeed biologically evolved – that we can count because counting was a useful thing for our brains to be able to do.

I would like some citations for this. This is the first I've heard of this, and I previously have assumed that it was universally accepted that this was not the case.

This article makes similar claims at multiple points, without corroboration. "researchers have concluded", "researchers often assume", "researchers have argued", for arguments that I have never heard made.
