ABSTRACT
This chapter looks at four major fallacies which can be easily detected in current evolutionary linguistics. A possible scenario of language evolution which helps eliminate these fallacies will be suggested. The goal is to eliminate these fallacies in order to establish the underpinnings for a truly inter-/cross-disciplinary development of evolutionary linguistics. The chapter discusses the faculty of language in the narrow sense (FLN)/faculty of language in the broad sense (FLB) dichotomy that is an illusion and that Merge also had an evolutionary precursor. Hauser proposed the dichotomy between a FLN and a FLB, FLN being the component of language which is both species-specific and domain-specific, while FLB includes FLN and every other component which is not specific in one way or another. To the extent that FLN is species-specific and evolutionarily discontinuous, its existence presents a barrier to studies of language evolution.
