“…For the first forty or fifty years since Chomsky wrote his famous work Syntactic Structures (1957), many linguists and behavioural scientists have, following Chomsky's lead, attempted to argue that language is indeed innate in its base (i.e., the Language Acquisition Device), and that it is a uniquely human ability (e.g., Chomsky, 1966Chomsky, , 1975Chomsky, , 2002Chomsky, , 2010Gallistel, 2007;Hocket, 1966;Pinker, 1994) partly thanks to new discoveries about humans' ability of recursion and discrete infinity (cf. Tiede & Stout, 2010). In recent years in particular, though, researchers have begun to question the language-innateness hypothesis (e.g., Evans, 2014;Croft & Cruse, 2004;Goldberg, 2006;Tomasello, 2003Tomasello, , 2005, presenting increasingly more evidence in favour of the claim that the language learning capability is not some separate function of the human brain and that the once clear-cut distinction between animal communication systems and human language abilities is arguably not so clear-cut after all.…”
