Discussion of Indo-European origins and dispersal focuses on two hypotheses. Qualitative evidence from reconstructed vocabulary and correlations with archaeological data suggest that IndoEuropean languages originated in the Pontic-Caspian steppe and spread together with cultural innovations associated with pastoralism, beginning c. 6500–5500 bp. An alternative hypothesis, according to which Indo-European languages spread with the diffusion of farming from Anatolia, beginning c. 9500–8000 bp, is… Expand
Dated language phylogenies shed light on the ancestry of Sino-Tibetan
TLDR
A database of comparative linguistic data is developed and phylogenetic methods are used to infer phylogenies that date the origin of the Sino-Tibetan language family to around 7200 B.P. and suggest a link to the late Cishan and the early Yangshao cultures. Expand
Ancestry sampling for Indo-European phylogeny and dates
TLDR
It is found that the total evidence dating based on a birth death tree infers age which is consistent with the Steppe hypothesis of spread of Indo-European languages. Expand
Formal Syntax and Deep History
TLDR
It is shown that, contrary to long-standing assumptions, syntactic traits, modeled here within the generative biolinguistic framework, provide insights into deep-time language history and the diversity of nominal structures is encoded using 94 universally definable binary parameters. Expand
BEASTling: A software tool for linguistic phylogenetics using BEAST 2
TLDR
BEASTling transforms comparatively short and human-readable configuration files into the XML files used by BEAST to specify analyses, and allows the user to conveniently filter datasets using names for recognised language families, to impose monophyly constraints so that inferred language trees are backward compatible with Glottolog classifications. Expand
Lateral transfer in Stochastic Dollo models
TLDR
This work illustrates the method on a data set of lexical traits in Eastern Polynesian languages and obtains an improved fit over the corresponding model without lateral transfer. Expand
Investigating diachronic trends in phonological inventories using BDPROTO
TLDR
An expanded version of bdproto, a database comprising phonological inventory data from 257 ancient and reconstructed languages, is presented, and whether consonantal and vocalic systems differ in their rates of change over the last 10,000 years is investigated. Expand
Cultural Evolution: A Review of Theory, Findings and Controversies
TLDR
An overview of the theory of cultural evolution is provided, including its intellectual history, major theoretical tenets and methods, key findings, and prominent criticisms and controversies, to highlight the value of using evolutionary methods to study culture for both the social and biological sciences.

An Alternative to ‘Celtic from the East’ and ‘Celtic from the West’
This article discusses a problem in integrating archaeology and philology. For most of the twentieth century, archaeologists associated the spread of the Celtic languages with the supposed westwardExpand
An Automated Framework for Fast Cognate Detection and Bayesian Phylogenetic Inference in Computational Historical Linguistics
We present a fully automated workflow for phylogenetic reconstruction on large datasets, consisting of two novel methods, one for fast detection of cognates and one for fast Bayesian phylogeneticExpand
Pseudo Dollo models for the evolution of binary characters along a tree
TLDR
The pseudo Dollo model is introduced, a model of character evolution along a tree that can be formulated as a three-state continuous time Markov chain (CTMC) model, and it is demonstrated it can have a better fit than some of the popular alternative models on some real world datasets. Expand

How Accurate and Robust Are the Phylogenetic Estimates of Austronesian Language Relationships?
TLDR
The results show that the Austronesian language phylogenies are highly congruent with the traditional subgroupings, and the date estimates are robust even when calculated using a restricted set of historical calibrations. Expand
Mapping the Origins and Expansion of the Indo-European Language Family
TLDR
Both the inferred timing and root location of the Indo-European language trees fit with an agricultural expansion from Anatolia beginning 8000 to 9500 years ago, which supports the suggestion that the origin of the language family was indeed Anatolia 7 to 10 thousand years ago—contemporaneous with the spread of agriculture.

Two IE phylogenies , three PIE migrations , and four kinds of steppe pastoralism
This paper defends and elaborates a Pontic-Caspian steppe homeland for PIE dated broadly between 4500–2500 bc. First I criticize the Bouckaert et al. phylogeny, rooted in Anatolia, published inExpand
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
Austronesian language phylogenies: myths and misconceptions about Bayesian computational methods
TLDR
Phylogenetic analyses of structural features have revealed historical signals in Papuan and reflected a settlement pattern through Island South-East Asia, New Guinea and then into Oceania, consistent with the ‘Out of Taiwan’ scenario. Expand
Does horizontal transmission invalidate cultural phylogenies?
TLDR
This work uses a natural model of linguistic evolution to simulate borrowing between languages and demonstrates that realistic levels of reticulation between cultures do not invalidate a phylogenetic approach to cultural and linguistic evolution. Expand
Language trees support the express-train sequence of Austronesian expansion
TLDR
This analysis uses this analysis to test competing hypotheses—the “express-train” and the “entangled-bank” models—for the colonization of the Pacific by Austronesian-speaking peoples and finds that the topology of the language tree was highly compatible with the express-train model. Expand
Time depth, convergence theory, and innovation in proto-indo-european : 'Old Europe' as a PIE linguistic area
