    Grambank reveals the importance of genealogical constraints on linguistic diversity and highlights the impact of language loss
    (Center for Open Science, 2022-12-04)
    While global patterns of human genetic diversity are increasingly well characterized, the diversity of human languages remains less systematically described. Here we outline the Grambank database. With over 400,000 data points and 2,400 languages, Grambank is the largest comparative grammatical database available. The comprehensiveness of Grambank allows us to quantify the relative effects of genealogical inheritance and geographic proximity on the structural diversity of the world's languages, evaluate constraints on linguistic diversity, and identify the world's most unusual languages. An analysis of the consequences of language loss reveals that the reduction in diversity will be strikingly uneven across the major linguistic regions of the world. Without sustained efforts to document and revitalize endangered languages, our linguistic window into human history, cognition and culture will be seriously fragmented.

    Exploring Amazonian Cognitive Diversity at Chana Research Station
    (Wiley, 2026-01-01)
    The Chana Research Station for Language Sciences and Interculturality is a scientific initiative dedicated to exploring the linguistic, cultural, and cognitive diversity of the Peruvian Amazon. Building on long-standing local partnerships and collaborations, Chana facilitates research on cognition that extends beyond populations from industrialized democracies, traditionally overrepresented in behavioral sciences. Other populations-such as those in Amazonia-exhibit remarkable diversity. With this in mind, current Chana projects and collaborations encompass research on how Amazonian unique linguistic structures and culturally significant practices shape language processing and acquisition, as well as nonlinguistic cognition; studies on cognition focused on quantification practices in cultures with limited or unconventional numeral systems; and cross-cultural investigations of perception, building on prior research in other regions of the Amazon and the world. Beyond human cognition, the station has also supported experimental research on the relationship between domesticated dogs and their owners. Chana prioritizes inclusive and ethical research that benefits and includes local communities and their perspectives by engaging local and Indigenous researchers, and leading social and educational projects focused on cultural revitalization. Chana welcomes collaboration with researchers who are interested in advancing the understanding of Amazonian societies, languages, and knowledge systems.
