The Chinese Room makes a modularity assumption
Searle's argument assumes that certain functional parts of human cognitive performance (eg the ability to speak Chinese) can be modelled independently of the other functional parts of the system. Evolutionary biology suggests this isn't the case.
Evolutionary biology suggests that language cannot be modelled independently of other sensorimotor capacities, because linguistic capacities never exist without these evolutionary more primitive capacities.
