Agent-based language evolution experiments in PLOS ONE

Why do so many languages display grammatical agreement between particular linguistic units such as words or phrases? How did it result in the numerous varieties of agreement markers that we find today? A recent publication in PLOS ONE by Katrien Beuls and Luc Steels explores these questions by making use of agent-based models that simulate linguistic interactions in an open population of language users. It shows for the first time how grammaticalisation processes may occur and spread through a population. The open-access article can be read here: http://dx.plos.org/10.1371/journal.pone.0058960.
