Songbirds learn their songs much as human infants learn language — by listening to adults during a critical developmental window. Yet songbird learning is not simple imitation. Young birds produce a "subsong," a babbling-like phase, and then refine it through feedback against an internal template. Some neurobiologists treat this multistage process as a model for understanding how human children move from babble to speech.
Which choice best states the main idea of the text?
- A
Babbling is a uniquely human behavior.
- B
Songbirds and humans share an identical learning mechanism.
- Ccheck_circle
Songbird vocal learning resembles human language acquisition closely enough to serve as a research model.
- D
Songbirds copy adult songs without modification.
Explanation
The passage carefully positions the parallel as close enough to be a model — B. A overstates ("identical"); C and D contradict the text.
