Research Overview

The Department of Linguistic and Cultural Evolution aims to answer big picture questions about human history. Our focus is on describing and explaining the major patterns of linguistic and cultural variation across the globe. To achieve this aim we bring together anthropologists, computer scientists, evolutionary biologists, linguists and social scientists. Together we tackle these questions by developing novel language documentation methods, global linguistic and cultural databases, and analyses using evolutionary theories and computational methods. This thoroughly interdisciplinary approach enables us to combine the quantitative rigour of the natural sciences while still utilising the insights that only come from maintaining close contact with the primary linguistic and cultural data.

Research Areas

The Evolution of Linguistic Diversity

Three fundamental facts about language demand explanation:

  • Why are there approximately 7000 languages spoken today?
  • Why is their distribution across the globe so uneven?
  • Why do they differ so much?

We address these questions with a combination of linguistic databases (Glottobank, IE-CORTransNewGuinea.org, Austronesian Basic Vocabulary Database, Tsammalex, Glottolog, Dictionaria), computational methods (CALC), carefully targeted fieldwork, and sociohistorical methods (CoOL).

Projects exploring linguistic diversity:


Glottobank is an international research consortium established to document and understand the world’s linguistic diversity. We are developing methods to use this data to make inferences about human prehistory, relationships between languages and processes of language change.



CoOL (Comparative Oceanic Linguistics) combines methods of classic comparative historical linguistics, computational linguistics, and sociolinguistics to reconstruct the Oceanic past and to explore how high mobility, overlapping migrations, and complex interactions have impacted language histories.



Computer-Assisted Language Comparison (CALC) While purely computational approaches are common today, the ERC-funded research project focuses on the communication between classical and computational linguists, developing interfaces that allow historical linguists to produce their data in machine-readable formats while at the same time presenting the results of computational analyses in a transparent and human-readable way.



IE-CoR is a database designed to explore how languages within a family relate to each other in Cognate Relationships in their ‘core’ vocabulary. The CoR framework and online database explorer are tailored to serve both qualitative and quantitative/phylogenetic research purposes. IE-CoR already covers Indo-European, but the model is extendable to any language family.



TransNewGuinea.org is a database of the languages of New Guinea. Vanishingly little is known about these languages' history, and this project aims to reveal the prehistory of New Guinea using the linguistic comparative method combined with novel computational phylogenetic methods.


Austronesian Basic Vocabulary Database

Austronesian Basic Vocabulary Database - Die Datenbank des austronesischen Grundwortschatzes beinhaltet lexikalische Daten zahlreicher pazifischer Sprachen für einen umfassenden Sprachvergleich. Mit Wortlisten für mehr als 1.500 Sprachen des asiatisch-pazifischen Raums ist sie eine der weltweit größten sprachübergreifenden Datenbanken.



Tsammalex is a multilingual lexical database on plants and animals including linguistic, anthropological and biological information as well as images. It has been set up as a resource for linguists, anthropologists and other researchers, language planners and speech communities interested in the conservation of their biological knowledge. Lexical and biological data can be accessed directly or filtered for specific languages or geographical regions, with varying details.



Glottolog is a comprehensive catalogue of the world’s languages, language families and dialects (languoids). It assigns stable identifiers to all languoids, shows their location and provides links to other resources on the world’s languages. In addition, it gives numerous bibliographical references on all languages. Glottolog is being constantly updated with the help of the worldwide community of linguists.



Dictionaria is an open-access journal that publishes high-quality dictionaries of languages from around the world, especially languages that do not have a large number of speakers. The dictionaries are published not in the traditional linear form, but as electronic databases that can be easily searched, linked and exported.


The Evolution of Cultural Diversity

Recent decades have seen a blossoming of multidisciplinary research on human culture and cultural change from an evolutionary perspective. Major questions for the field include:

  • How and why does cultural diversity emerge?
  • What processes maintain and stabilise cultural variability, boundaries and identities?
  • What causes cultural diversity to be lost?

We bring together researchers from the social and biological sciences to work on fundamental questions in cultural evolution at both the macro and the micro level. We document cultural diversity across world regions and throughout human history using both primary and secondary data sources. Our projects focus on demographic and anthropological data collection, and on building large-scale quantitative cross-cultural databases of historic and contemporary cultures. We apply a wide range of computational and statistical methods with comparative cultural data to test hypotheses about cultural evolution, and combine these with contemporary and historical ethnographic work.

Projects exploring cultural diversity:


Cultural evolution of religion – we combine cross-cultural data with computational methods to test theories about the evolution of supernatural beliefs and practices. Our recent research has focused on understanding how features of religion have co-evolved with the structure of human social systems and the physical environments that we live in.



The Database of Places, Languages, Culture and Environment (D-PLACE) systematically brings together cultural, linguistic, environmental and geographic information for over 1400 preindustrial societies. By linking societies to their geographic locations and through their shared linguistic ancestry, we employ computational methods to investigate the roles of environment, spatial proximity and cultural ancestry in observable patterns of cross-cultural diversity across world regions.


Genes, language, culture

Genetics has revolutionised our understanding of the human past, uncovering the details of our evolution as well as the complexities of our more recent history. By analysing genetic data alongside cultural and linguistic data, we address the following broad research questions:

  • How or where do genetic histories match those from archaeology and historical linguistics?
  • What kind of cultural processes create or maintain genetic diversity?
  • How can we best integrate genetic inferences with those from other historical sciences?

We develop and apply a range of methods from across population genetics, cultural evolution and gene-culture coevolution to build unified models of human history. We integrate modern DNA data from targeted fieldwork projects in Mali, Peru and Vanuatu, ancient DNA data generated with collaborators in the Department of Archaeogenetics, and linguistic and cultural data from colleagues in the Department of Linguistic and Cultural Evolution.

Projects exploring Genes, Language, Culture:


Genes and Languages Together - This project focuses on the matches and mismatches between linguistic and genetic variation. To explore this parallel, we assemble a new genetic databases to be matched with relevant qualitative and quantitative linguistic and cultural information.
