Passage A
For decades, a prominent school of evolutionary linguistics has maintained that human language capacity emerged rapidly through a single genetic mutation that enabled "Merge"—the cognitive operation allowing humans to combine concepts into recursive hierarchical structures. Proponents of this saltational model argue that recursive syntax is an all-or-nothing neurological property rather than a trait built incrementally by natural selection. According to this view, anatomical readiness, such as the lowering of the larynx, was a secondary adaptation. The primary evidence cited for this sudden appearance is the abrupt emergence of symbolic artifacts—such as engraved ochre blocks and personal ornaments—in the archaeological record of anatomically modern humans approximately 70,000 years ago. Proponents assert that because symbolic representation requires recursive mental capacity, the absence of widespread symbolic artifacts prior to this period demonstrates that true syntactic language did not exist in earlier hominin species.
Passage B
While symbolic artifacts offer compelling proof of abstract thought, relying exclusively on them to date the origin of language overlooks a crucial domain of material evidence: lithic technology. The production of Middle Paleolithic stone tools, particularly using the Levallois knapping technique starting around 300,000 years ago, required sequential planning, working memory, and hierarchical rule execution identical to the cognitive architecture underpinning syntax. Experimental neuroimaging of modern flintknappers reveals that crafting these complex tools activates the exact same frontoparietal brain networks employed during syntactic sentence processing. This neural overlap indicates that the capacity for hierarchical sequence processing co-evolved gradually with complex motor control and social transmission over hundreds of thousands of years. Consequently, treating language as a sudden, recent mutation ignores the deep evolutionary continuity of the cognitive prerequisites for syntax demonstrated by the prehistoric toolmaking record.
Based on both passages, how would the author of Passage B most likely characterize the claim in Passage A that the absence of symbolic artifacts before 70,000 years ago proves syntactic language had not yet emerged?
- As an incomplete assessment that mistakes a shift in cultural expression for the initial emergence of cognitive architecture.Cevap
- BAs a flawed conclusion because stone tool production using the Levallois technique directly generated symbolic artifacts much earlier.
- CAs an accurate observation that confirms the frontoparietal brain network developed exclusively in response to ornamental art.
- DAs a valid premise that correctly identifies anatomical adaptations like larynx lowering as the true precursor to syntax.
