 Thus, the mere fact that language is unique to humans is sufficient to rule out monkey and primate call systems as preadapations for language. But, contra Bickerton, a neo-Darwinian like Jackendoff (2002) appeals to the work of Dunbar (1998), Power (1998), Worden (1998) to provide a selectionist story which assumes that cooperation in hunting, defense (Pinker and Bloom 1990), and “ ‘social grooming’ or deception” are selective forces that operated on human ancestors to drive increases in expressive power that distinguishes non-human communication and human linguistic capacities and systems. Bickerton (2014), however, combines aspects of Essentialism, Emergentism, and Externalism by taking equal parts of Minimalism, primatology, and cultural evolution into a more holistic account. He specifically tailors a niche construction theory to explain the emergence of displaced, discrete symbolization in a particular kind of primate, namely human beings. He thus allows for (a) and (b) to figure in an explanation of (c). This is somewhat of a departure from his earlier positions.
