Rethinking syntax: A commentary on E. Kako's ''Elements of syntax in the systems of three language-trained animals''

Abstract: Kako (1999) requests new studies of linguistic continua between humans and nonhumans. I question the value of such studies and the importance of determining whether any component of language is uniquely human. I argue that training of specific constructs (e.g., dosed classes) may not provide appropriate data, and that whether a particular species lacks or has human-like syntax likely results from specific ecological/evolutionary pressures. Social factors purported to drive intelligence and communication in primates likely exist for nonprimates such as parrots; moreover, Grey parrots demonstrate rudiments of supposedly uniquely human abilities: supralaryngeal vocal tract control, anticipatory coarticulation, and sound play.
