A study of an Amazonian tribe is stoking fierce debate about whether people can count without numbers.

When are the researchers going to address really challenging problems?

Such as, do lepers who have lost one or more digits to their disease switch to something other than a base-10 numeric system?

I believe you're on to something.

Perhaps these Amazonians are utilizing a "limb-based" mathmatics, instead of a digital one.
