Recent research on the processes of linguistic diversification has highlighted a number of similarities with the processes that give rise to biological diversity. For example, several studies have shown that latitudinal gradients in linguistic diversity parallel those observed in species diversity. Likewise, it is now widely accepted by linguists that languages, like species, arise through descent with modification. These similarities strongly suggest that linguistic evolution and biological evolution share processes in common. As such, models of speciation and evolutionary ecological techniques may help us reach a better understanding of linguistic diversity. In this project, we will test the hypothesis that the ecological processes that lead to the evolution of species diversity in animal populations are also responsible for the evolution of linguistic diversity among human groups. We will use newly developed phylogenetic techniques that enable us to test hypotheses not only about whether some traits are correlated with other traits across phylogenetically related species, but also whether certain traits cause one group of species to become more numerous or more likely to go extinct. The data sets used will be created from published databases of indigenous linguistic diversity prior to European colonisation, and analyses will be carried out on a continent-by-continent basis, with particular emphasis on Africa.
