Historical Bio-Linguistics : A biostatistic approach to the study of linguistic phylogenies and the correlation of genetic, linguistic and geographical data (original) (raw)

Genetics, linguistics, and prehistory: thinking big and thinking straight

Antiquity, 1998

Many claims have been made linking ancient languages with genetically identified prehistoric and modern populations. There is much new ‘evidence’ and intense debate on the validity and appropriateness of such interdisciplinary work. Here Patrick Sims-Williams provides a timely comment on linguistics and the quest for ancient populations.

Interdisciplinary indiscipline? Can phylogenetic methods meaningfully be applied to language data -- and to dating language

Phylogenetic Methods and the Prehistory of Languages, 2006

A number of recent papers have sought to apply to language data various phylogenetic ‘tree drawing’ techniques initially developed for uses outside linguistics. The reaction from many historical linguists, however, has typically been critical, if not outright hostile. This paper explores, and aims to explain, why it is that there has been such a long running failure to reach a consensus between linguists and specialists from other disciplines, notably genetics and archaeology. We consider linguists’ fundamental concerns as to how non linguists go about using language data; especially whether (and if so, how) one can meaningfully use such phylogenetic analyses on language data, interpret their results, and attempt to put dates on particular nodes in the trees. We look into certain aspects of the very nature of language that it is crucial to bear in mind in order to handle language data appropriately for these purposes, but which many linguists feel are not truly appreciated by non linguists. These aspects include: language’s inherent susceptibility to powerful external forces which vary tremendously through history; the nature of language data and what this means for how they can meaningfully be compared and measured; and the nature of language change and historical development, with important consequences for the interpretation of those data, not least for dating. It emerges, moreover, that these same characteristics of language change also challenge linguists’ own ‘established’ dating of Proto Indo European by the so called ‘linguistic palaeontology’, and how that question is in truth much more open than Indo Europeanist linguists generally admit.

Formal linguistics as a cue to demographic history

Beyond its theoretical success, the development of molecular genetics has brought about the possibility of extraordinary progress in the study of classification and in the inference of the evolutionary history of many species and populations. A major step forward was represented by the availability of extremely large sets of molecular data suited to quantitative and computational treatments. In this paper, we argue that even in cognitive sciences, purely theoretical progress in a discipline such as linguistics may have analogous impact. Thus, exactly on the model of molecular biology, we propose to unify two traditionally unrelated lines of linguistic investigation: 1) the formal study of syntactic variation (parameter theory) in the biolinguistic program; 2) the reconstruction of relatedness among languages (phylogenetic taxonomy). The results of our linguistic analysis have thus been plotted against data from population genetics and the correlations have turned out to be largely s...

Genetic Relationship among Languages: An Overview

2020

This paper reviews the basic concepts of historical linguistics and the comparative techniques used by various linguists who studied Indo-European and American languages to determine a shared ancestry among languages. This paper also evaluates the major concepts of historical linguistics and the well-grounded theories and classifications that have guided and shaped the modern linguistic classification practices. For over one and a half century, historical linguists have been deducing the origins of different languages. Genetic classifications have been proposed for languages from all parts of the world and thus far, 142 language-families have been identified. Although all of these classification schemes are controversial in terms of their validity and reliability but with the progress in the field of bioinformatics, the problems in linguistic reconstruction have been greatly resolved. Therefore, the historical classification schemes that have been proposed earlier are being radicall...
