In addition to its theoretical impact, the development of molecular biology has brought about the possibility of extraordinaryhistorical progress in the study of phylogenetic classification of different species and human populations (especially cf. CavalliSforza et al., 1994, among others).We argue that parametric analyses of grammatical diversity in theoretical linguistics, stemming from Chomsky (1981), can prompt analogous progress in the historical classification of language families, by showing that abstract syntactic properties are reliable indicators of phylogenetic relations. The pursuit of this approach radically questions the traditional belief in the orthogonality of grammatical typology and language genealogy, broadly supporting Nichols’ (1992) program, and ultimately contributes to establishing formal grammar as a population science and historical linguistics as animportant part of cognitive inquiry
Objectives: The notion that patterns of linguistic and biological variation may cast light on each other and on population histories dates back to Darwin's times; yet, turning this intuition into a proper research program has met with serious methodological difficulties, especially affecting language comparisons. This article takes advantage of two new tools of comparative linguistics: a refined list of Indo‐European cognate words, and a novel method of language comparison estimating linguistic diversity from a universal inventory of grammatical polymorphisms, and hence enabling comparison even across different families. We corroborated the method and used it to compare patterns of linguistic and genomic variation in Europe. Materials and Methods: Two sets of linguistic distances, lexical and syntactic, were inferred from these data and compared with measures of geographic and genomic distance through a series of matrix correlation tests. Linguistic and genomic trees were also estimated and compared. A method (Treemix) was used to infer migration episodes after the main population splits. Results: We observed significant correlations between genomic and linguistic diversity, the latter inferred from data on both Indo‐European and non‐Indo‐European languages. Contrary to previous observations, on the European scale, language proved a better predictor of genomic differences than geography. Inferred episodes of genetic admixture following the main population splits found convincing correlates also in the linguistic realm. Discussion: These results pave the ground for previously unfeasible cross‐disciplinary analyses at the worldwide scale, encompassing populations of distant language families.

The Parametric Comparison Method (PCM, Guardiano & Longobardi 2005, Longobardi & Guardiano 2009) is grounded on the assumption that syntactic parameters are more appropriate than other traits for use as comparanda for historical reconstruction, because they are able to provide unambiguous correspondences and objective measurements, thus guaranteeing wide-range applicability and quantitative exactness. This article discusses a set of experiments explicitly designed to evaluate the impact of parametric syntax in representing historical relatedness, and performed on a selection of 26 contemporary Indo-European varieties. The results show that PCM is in fact able to correctly identify genealogical relations even from modern languages only, performing as accurately as lexical methods, and that its effectiveness is not limited by interference effects such as ‘horizontal’ transmission. PCM is thus validated as a powerful tool for the analysis of historical relationships not only on a long-range perspective (as suggested by Longobardi & Guardiano 2009), but even on more focused, though independently well-known domains.

We show that, contrary to long-standing assumptions, syntactic traits, modeled here within the generative biolinguistic framework, provide insights into deep-time language history. To support this claim, we have encoded the diversity of nominal structures using 94 universally definable binary parameters, set in 69 languages spanning across up to 13 traditionally irreducible Eurasian families. We found a phylogenetic signal that distinguishes all such families and matches the family-internal tree topologies that are safely established through classical etymological methods and datasets. We have retrieved “near-perfect” phylogenies, which are essentially immune to homoplastic disruption and only moderately influenced by horizontal convergence, two factors that instead severely affect more externalized linguistic features, like sound inventories. This result allows us to draw some preliminary inferences about plausible/implausible cross-family classifications; it also provides a new source of evidence for testing the representation of diversity in syntactic theories.
The progressive spread of English as the main language of the international scientific communication has been interpreted and justified in many different ways by several scholars. The paper suggests a brief review of the scientific debate on such topics, focusing on the main stereotypes which have been created in order to provide explanations for the development of English as the language of science, and on the perception of non-Anglophone scholars concerning the reasons for the predominance of English in scientific literature and their disadvantages with respect to native speakers.Frequently used stereotypes on English as the language of science are analyzed and discussed in reference to the motivations asserted by linguists and non-linguists. A double ideological evidence can be registered: 1. arguments essentially consist in a-posteriori justifications, 2. English – far away from representing a free choice for non-native scholars – is perceived as the repository of the linguistic power that is desired and worshipped. The overview closes with the results of a pilot investigation on the languages of scientific publications, conducted on a sample of Italian scholars belonging to various scientific fields
It is still a widely held opinion that the contribution of formal syntactic theories to modern linguistics is essentially focused on synchronic generalizations and that it does not extend to the most classical problems of the historical paradigm. Such a belief is beginning to fade away as a consequence of increased work in diachronic syntax. This chapter argues that the generative theory of syntactic parameters might interestingly renovate another stronghold of the historical study of language, phylogenetic taxonomy, and undermine the Humboldtian received distinction between the latter and grammatical typology.
Objective: To propose a new approach for comparing genetic and linguistic diversity in populations belonging to distantly related groups. Background: Comparisons of linguistic and genetic differences have proved powerful tools to reconstruct human demographic history. Current models assume on both sides that similarities reflect either descent from common ancestry or the balance between isolation and contact. Most linguistic phylogenies are ultimately based on lexical evidence (roughly, words and morphemes with their sounds and meanings). However, measures of lexical divergence are reliable only for closely related languages, thus large-scale comparisons of genetic and linguistic diversity have appeared problematic so far. Methods: Syntax (abstract rules to combine words into sentences) appears more measurable, universally comparable, and stable than the lexicon, and hence certain syntactic similarities might reflect deeper linguistic relationships, such as those between distant language families. In this study, we for the first time compared genetic data to a matrix of syntactic differences among selected populations of three continents. Results: Comparing two databases of microsatellite (Short Tandem Repeat) markers and Single Nucleotides Polymorphisms (SNPs), with a linguistic matrix based on the values of 62 grammatical parameters, we show that there is indeed a correlation of syntactic and genetic distances. We also identified a few outliers and suggest a possible interpretation of the overall pattern. Conclusions: These results strongly support the possibility of better investigating population history by combining genetic data with linguistic information of a new type, provided by a theoretically more sophisticated method to assess the relationships between distantly related languages and language families.
