We present the first proposal of detailed internal subgrouping and higher-order structure of the Pama-Nyungan family of Australian languages. Previous work has identified more than twenty-five primary subgroups in the family, with little indication of how these groups might fit together. Some work has assumed that reconstruction of higher nodes in the tree was impossible, either because extensive internal borrowing has obscured more remote relations, or because the languages are not… Expand

Bayesian phylolinguistics reveals the internal structure of the Transeurasian family
The historical connection between the Transeurasian languages, i.e. the Japonic, Koreanic, Tungusic, Mongolic, and Turkic languages, is among the most disputed issues of historical linguistics. Here,Expand
Bayesian phylolinguistics infers the internal structure and the time-depth of the Turkic language family
Despite more than 200 years of research, the internal structure of the Turkic language family remains subject to debate. Classifications of Turkic so far are based on both classicalExpand
The origin and expansion of Pama–Nyungan languages across Australia
TLDR
A Bayesian phylogeographic analysis of vocabulary from 306 Pama–Nyungan languages suggests that the language family rose to dominance across Australia in a process of rapid replacement following an origin in the Gulf Plains region during the mid-Holocene. Expand
Detecting non-tree-like signal using multiple tree topologies
TLDR
It is shown that the multiple topologies method is a useful tool to study the dynamics of language evolution and suggested that reticulation may arise from a number of processes, including dialect chain break-up, borrowing, and characteristics of lexical datasets. Expand
What ’ s in a Name ? A Typological and Phylogenetic Analysis of the Names of Pama-Nyungan Languages
The naming strategies used by Pama-Nyungan languages to refer to themselves show remarkably similar properties across the family. Names with similar meanings and constructions pop up across theExpand
A Bayesian approach to the classification of Tungusic languages
The Tungusic language family is comprised of languages spoken in Siberia, the Russian Far East, Northeast China and Xinjiang. There is a general consensus that these languages are genealogicallyExpand
Quantifying uncertainty in the phylogenetics of Australian numeral systems
TLDR
It is shown that these systems do not increment serially, but most commonly vary their upper limits between 3 and 5, while there is evidence for rapid system elaboration beyond the lower limits, languages lose numerals as well as gain them. Expand
The Phylogenetic Status of Pacific Coast Athabaskan: A Computational Assessment
In lieu of an abstract, here is a brief excerpt: The present study considers the status of the Pacific Coast Athabaskan languages, both in relation to each other and in relation to the rest of theExpand
Using ancestral state reconstruction methods for onomasiological reconstruction in multilingual word lists
TLDR
A pilot study exploring how well automatic methods for ancestral state reconstruction perform in the task of onomasiological reconstruction in multilingual word lists finds that Maximum Likelihood largely outperforms the other methods, but the general performance was disappointingly low. Expand
Using ancestral state reconstructionmethods for onomasiological reconstruction in multilingual word lists *
Current efforts in computational historical linguistics are predominantly concerned with phylogenetic inference. Methods for ancestral state reconstruction have only been applied sporadically. InExpand

This paper builds on a previous work in which we attempted to retrieve a phylogenetic signal using abstract structural features alone, as opposed to cognate sets, drawn from a sample of IslandExpand
Relaxed Phylogenetics and Dating with Confidence
TLDR
This work describes how it can be used to estimate phylogenies and divergence times in the face of uncertainty in evolutionary rates and calibration times and provides a means for measuring the clocklikeness of datasets and comparing this measure between different genes and phylogenies. Expand
DensiTree: making sense of sets of phylogenetic trees
TLDR
DensiTree provides a quick method for qualitative analysis of tree sets by drawing all trees in the set transparently to get an impression of properties of the tree set such as well-supported clades, distribution of tMRCA and areas of topological uncertainty. Expand
Does Lateral Transmission Obscure Inheritance in Hunter-Gatherer Languages?
TLDR
The results debunk the myth of high borrowing in hunter-gatherer languages and suggest that the evolution of these languages is governed by the same type of rules as those operating in large-scale agriculturalist speech communities. Expand

Modeling the covarion hypothesis of nucleotide substitution.
TLDR
A covarion-style model for nucleotide substitution that allows sites to turn "on" and "off" with time is analyzed and it is shown how to obtain the evolutionary distance between two species from the expected proportion of sites where two species differ. Expand
Hierarchical phylogenetic models for analyzing multipartite sequence data.
TLDR
This work proposes an alternative middle ground by constructing a Bayesian hierarchical phylogenetic model that returns substantially more precise continuous parameter estimates than an independent parameter approach without losing the salient features of the data. Expand
Your place or mine? A phylogenetic comparative analysis of marital residence in Indo-European and Austronesian societies
TLDR
Language trees derived using phylogenetic tree-building techniques on Indo-European and Austronesian vocabulary data are used to statistically reconstruct past marital residence and infer rates of cultural change between different residence forms, showing Proto-Indo-European to be virilocal and Proto-Malayo-Polynesian uxorilocal.

Abstract This paper shows that despite evidence of structural convergence between some of the Austronesian and non-Austronesian (Papuan) languages of Island Melanesia, statistical methods can detectExpand
Lexical replacement and cognate equilibrium in Australia
TLDR
It is found that borrowing accounts for at most half of lexical replacement in these languages, and most usually is well below half, and this rate is crucial in the prediction of what fraction of vocabulary might in the long term be common to two neighbouring languages. Expand
