Question

For decades, the theoretical scaffolding of generative linguistics rested on the axiom that recursion—the capacity to embed structures within structures endlessly—constitutes the singular, defining property of the human language faculty. Consequently, when field research suggested that the Amazonian language Pirahã entirely lacks recursive syntactic structures, empirical linguists heralded the finding as a fatal blow to the generativist paradigm. If a natural human language operated without recursion, they argued, Universal Grammar was effectively falsified.

However, contemporary generativists have largely insulated their framework from this anthropological critique through a strategic theoretical recalibration. Rather than disputing the field data, theorists have refined the distinction between the Faculty of Language in the Broad sense (FLB) and the Faculty of Language in the Narrow sense (FLN). Under this revised architecture, recursion is allocated strictly to the FLN as an innate cognitive computational mechanism, but it is not mandated to manifest in the overt syntactic outputs of every individual language. To clarify this pivot, proponents frequently point to the absence of wheels in pre-Columbian American societies. Just as the failure to utilize wheeled transport does not imply a biological or cognitive inability to comprehend rotational mechanics among indigenous populations, the absence of recursive syntax in Pirahã does not negate the existence of an innate human computational capacity for recursive thought. Thus, the generativist paradigm survives the Pirahã anomaly by redefining recursion from an obligatory feature of linguistic performance to a latent cognitive competence.

Which of the following best describes the author's primary purpose in referring to the "absence of wheels in pre-Columbian American societies"?
