CARTA: How Language Evolves
This symposium addresses the question of how human language came to have the kind of structure it has, focusing on three sources of evidence: 1) ways languages get new structure not present in the language of the previous generation(s) of speakers or signers; 2) what contrasts between new and mature languages reveal about how language evolves; and 3) neuroscientific investigations of functional specialization for language in the human brain and its dependence on the linguistic input the language learner gets during cognitive development.
