 The FLN/FLB distinction provides earlier generative Essentialism with an answer (at least in part) to the question of what the singularity of the human language faculty consists in, and it does so in a way that subsumes many of the empirical discoveries of paleoanthropology, primatology, and ethnography that have been part of highly influential in Emergentist approaches as well as neo-Darwinian Essentialist approaches. A neo-Darwinian Essentialist like Pinker will accept that the language faculty involves recursion, but also will also hold (with Emergentists) that human language capacities originated, via natural selection, for the purpose of linguistic communication.
