Statistical methods fashionable again in Linguistics: Reconstructing Proto-Australian dialects

Reconstructing remote relationships – Proto-Australian noun class prefixation, by Mark Harvey & Robert Mailhammer, Diachronica (2017) 34(4): 470–515

Abstract:

Evaluation of hypotheses on genetic relationships depends on two factors: database size and criteria on correspondence quality. For hypotheses on remote relationships, databases are often small. Therefore, detailed consideration of criteria on correspondence quality is important. Hypotheses on remote relationships commonly involve greater geographical and temporal ranges. Consequently, we propose that there are two factors which are likely to play a greater role in comparing hypotheses of chance, contact and inheritance for remote relationships: (i) spatial distribution of corresponding forms;

The origin and expansion of Pama–Nyungan languages across Australia

Yet another questionable paper by Nature, The origin and expansion of Pama–Nyungan languages across Australia, by Bouckaert, Bowern & Atkinson, Nat Ecol Evol (2018).

Abstract:

It remains a mystery how Pama–Nyungan, the world’s largest hunter-gatherer language family, came to dominate the Australian continent. Some argue that social or technological advantages allowed rapid language replacement from the Gulf Plains region during the mid-Holocene. Others have proposed expansions from refugia linked to climatic changes after the last ice age or, more controversially, during the initial colonization of Australia. Here, we combine basic vocabulary data from 306 Pama–Nyungan languages with Bayesian phylogeographic
