Chomsky's universal grammar aligns with theories of the biological evolution of human language

Is it true that Chomsky's universal grammar aligns with theories of the biological evolution of human language?

Partly. While traditional biolinguistic perspectives attempt to align Chomsky's Universal Grammar with biological evolution and innateness, critics and modern comparative studies challenge this by emphasizing cultural evolution, gradual continuity from non-human cognitive capacities, and biological variation that complicates rigid innateness models.

The analysis

The retrieved papers show a genuine division in the field. Papers [0], [1], [7], and [11] link generative linguistics, innateness, and biolinguistics directly to evolutionary biology and the human faculty of language. Conversely, papers [3], [5], and [6] explicitly challenge core assumptions of Universal Grammar from evolutionary, genetic, and comparative angles, arguing for cultural evolution or gradual continuity from non-human precursors. Because both supportive frameworks and significant counterarguments or alternative evolutionary models are present in the sources, the verdict is CONTESTED.
