In this final chapter, we take on an issue that perhaps precedes all the others: how and why did language evolve? Linguistic theory has recently pivoted to amass considerable research on these questions. As we’ve seen over and over in the book, simpler structures have been posited across frameworks to account for the need to explain how language evolved. However, in this book, we’ve seen many distinct approaches to understand human language. A view of language evolution that permits the pluralism of the book would be consistent with the broad approach of this work. Therefore, in this chapter, I want to turn the minimalist research agenda on its head with an alternative thesis: natural language is a complex system and its emergence is likely to have been prompted by multiple interacting factors. First, we assess the current state of the art in biolinguistics and the strong saltation claim that goes with it. Then, we challenge the assumptions that’ve resulted in the saltation picture of language evolution on evolutionary grounds. Lastly, a radical approach to language evolution in terms of complexity science is proffered based on a unique connection with systems biology.
