Helen Davidson reports for the Guardian on a new study of Australian languages:
Most Indigenous languages in Australia likely originated from a remote spot in far north Queensland as recently as 4,000 years ago, before slowly spreading across the country, a new study has claimed.
The paper, published in the journal Nature on Tuesday, mapped the origins of the Pama-Nyungan family of languages, which encompasses about 90% of the continent. It traced the dominant family of languages back to an area near an isolated place known today as Burketown.
“All the languages from the Torres Strait to Bunbury, from the Pilbara to the Grampians, are descended from a single ancestor language that spread across the continent to all but the Kimberley and the Top End,” wrote co-author Claire Bowern, professor of linguistics at Yale University. “Where this language came from, how old it is, and how it spread, has been something of a puzzle.” […]
The researchers used an adapted computer model originally designed to map the spread of viruses, and built a family tree of “cognates” – identical or similar words across multiple languages. Pama-Nyungan is one of 28 Aboriginal or Torres Strait Islander language families. In contrast, Europe had four such families.
The results traced Pama-Nyungan back to a site south of the Gulf of Carpentaria, and indicate it emerged in the mid-Holocene period 4,000 to 6,000 years ago and rapidly replacing the existing languages.
It also aligned with archaeological discoveries in the region, including tool technologies which could explain the expansion across the continent, as could changes in ceremonies or marriage customs, the paper said. […]
“We’ve got a clearer picture now of when and where things started expanding, but there remains this question about exactly what drove it,” co-author Prof Quentin Atkinson of Auckland University’s school of psychology told Guardian Australia.
“What could possibly have happened to allow this group – initially one language – to spread across 90% of Australia and replace everyone else?”
Bowern discusses the study here, with a couple of useful maps; the paper itself, “The origin and expansion of Pama–Nyungan languages across Australia,” by Remco R. Bouckaert, Claire Bowern, and Quentin D. Atkinson, is behind a paywall. Thanks, Trevor!
