Mapping the Origins and Expansion of the Indo-European Language Family
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.
Language Phylogenies Reveal Expansion Pulses and Pauses in Pacific Settlement
The results are robust to assumptions about the rooting and calibration of the trees and demonstrate the combined power of linguistic scholarship, database technologies, and computational phylogenetic methods for resolving questions about human prehistory.
Language-tree divergence times support the Anatolian theory of Indo-European origin
An analysis of a matrix of 87 languages with 2,449 lexical items produced an estimated age range for the initial Indo-European divergence of between 7,800 and 9,800 years bp, in striking agreement with the Anatolian hypothesis.
Cycles of Contingency: Developmental Systems and Evolution
The book provides historical background to DST, recent theoretical findings on the mechanisms of heredity, applications of the DST framework to behavioural development, implications of DST for the philosophy of biology, and critical reactions to D ST.
Evolved structure of language shows lineage-specific trends in word-order universals
These findings support the view that—at least with respect to word order—cultural evolution is the primary factor that determines linguistic structure, with the current state of a linguistic system shaping and constraining future states.

Can ecological theory predict the distribution of foraging animals? A critical analysis of experiments on the ideal free distribution
Tests of the Ideal Free Distribution are reviewed utilising a method of analysis derived from the psychological principle called the matching law that revealed that the distribution of organisms is consistently less extreme than the Distribution of resources.
Language trees support the express-train sequence of Austronesian expansion
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.
mtDNA variation predicts population size in humans and reveals a major Southern Asian chapter in human prehistory.
Estimates of relative population sizes show remarkable concordance with the contemporary regional distribution of humans across Africa, Eurasia, and the Americas, indicating that mtDNA diversity is a good predictor of population size in humans.
The Austronesian Basic Vocabulary Database: From Bioinformatics to Lexomics
The technology underlying the ABVD is described and the benefits that an evolutionary bioinformatic approach can provide are discussed, including facilitating computational comparative linguistic research, answering questions about human prehistory, enabling syntheses with genetic data, and safe-guarding fragile linguistic information.
