“Buttressing this argument (that you can prevent children from learning to read or ride bicycles but you can’t stop them from learning to talk), Chomsky had pointed to two other universals in human language: that its emergence in children follows a very precise timetable of development, no matter where they live or which particular language is the first they learn; and that language itself has an innate structure. Chomsky has recently reminded audiences that the origins of the structure of language—how semantics and syntax interact—remain as “arcane” as do its behavioral and neurologic roots. Chomsky himself finds nothing in classical Darwinism to account for human language.* And for that reason, says Plotkin, linguistics is left with a major theoretical dilemma. If human language is a heritable trait but one that represents a complete discontinuity from animal communicative behavior, where did it come from?”
