What was the region of the brain that allows us to read used for in cultures without a written language?

And for that matter, how do we already have an *entire brain region* dedicated to the use of a specific tool that's still a recent innovation, evolutionarily speaking?

Reading uses a few regions.  Namely the temporal lobe, the broca's areas and  the angular and supramarginal gyrus.


The first two are also used in speech for phoneme and sound recognition and for language comprehension respectively.  The third set are responsible for linking the areas of the brains so the shapes can be linked to sounds then word and meaning.
