Via Phys.org, 27 Feb 2018: Linguistic persistence of the Austronesian language despite a change in the population in the South Pacific.
A new paper in the Proceedings of the National Academy of Science studies the rates of change between grammar and vocabulary in 81 Austronesian languages and finds that grammatical changes in language differ much quicker. The paper suggests a more nuanced reading of language evolution is needed in order to trace their movement in time.
Understanding how and why language subsystems differ in their evolutionary dynamics is a fundamental question for historical and comparative linguistics. One key dynamic is the rate of language change. While it is commonly thought that the rapid rate of change hampers the reconstruction of deep language relationships beyond 6,000–10,000 y, there are suggestions that grammatical structures might retain more signal over time than other subsystems, such as basic vocabulary. In this study, we use a Dirichlet process mixture model to infer the rates of change in lexical and grammatical data from 81 Austronesian languages. We show that, on average, most grammatical features actually change faster than items of basic vocabulary. The grammatical data show less schismogenesis, higher rates of homoplasy, and more bursts of contact-induced change than the basic vocabulary data. However, there is a core of grammatical and lexical features that are highly stable. These findings suggest that different subsystems of language have differing dynamics and that careful, nuanced models of language change will be needed to extract deeper signal from the noise of parallel evolution, areal readaptation, and contact.

Robots taking over us fleshling archaeologists? Climate change destroying archaeological sites? Yes! It’s true! And more! In this week’s edition of rojak.
This edition of rojak is an eclectic mix of tantalizing speculations about the hobbit’s role in linguistics, videos from Java and lego archaeology.
