A full-scale test of the language farming dispersal hypothesis
Author(s): Harald Hammarströmpp.: 197–213 (17)More LessOne attempt at explaining why some language families are large (while others are small) is the hypothesis that the families that are now large became large because their ancestral speakers had a technological advantage, most often agriculture. Variants of this idea are referred to as the Language Farming Dispersal Hypothesis. Previously, detailed language family studies have uncovered various supporting examples and counterexamples to this idea. In the present paper I weigh the evidence from ALL attested language families. For each family, I use the number of member languages as a measure of cardinal size, member language coordinates to measure geospatial size and ethnographic evidence to assess subsistence status. This data shows that, although agricultural families tend to be larger in cardinal size, their size is hardly due to the simple presence of farming. If farming were responsible for language family expansions, we would expect a greater east-west geospatial spread of large families than is actually observed. The data, however, is compatible with weaker versions of the farming dispersal hypothesis as well with models where large families acquire farming because of their size, rather than the other way around.

Do languages originate and become extinct at constant rates?
Author(s): Eric W. Holmanpp.: 214–225 (12)More LessThe shape of phylogenetic trees of language families is used to test the null hypothesis that languages throughout a family originate and go extinct at constant rates. Trees constructed either by hand or by computer prove to be more unbalanced than predicted, with many languages on some branches and few on others. The observed levels of imbalance are not explainable by errors in the trees or by the population sizes or geographic density of the languages. The results suggest changes in rates of origination or extinction on a time scale shorter than the time depth of currently recognized families.

Borrowability and the notion of basic vocabulary
Author(s): Uri Tadmor, Martin Haspelmath and Bradley Taylorpp.: 226–246 (21)More LessThis paper reports on a collaborative quantitative study of loanwords in 41 languages, aimed at identifying meanings and groups of meanings that are borrowing-resistant. We find that nouns are more borrowable than adjectives or verbs, that content words are more borrowable than function words, and that different semantic fields also show different proportions of loanwords. Several issues arise when one tries to establish a list of the most borrowing-resistant meanings: Our data include degrees of likelihood of borrowing, not all meanings have counterparts in all languages, many words are compounds or derivatives and hence almost by definition non-loanwords. We also have data on the age of words. There are thus multiple factors that play a role, and we propose a way of combining the factors to yield a new 100-item list of basic vocabulary, called the Leipzig-Jakarta list.

Homelands of the world’s language families: A quantitative approach
Author(s): Søren Wichmann, André Müller and Viveka Velupillaipp.: 247–276 (30)More LessA systematic, computer-automated tool for narrowing down the homelands of linguistic families is presented and applied to 82 of the world’s larger families. The approach is inspired by the well-known idea that the geographical area of maximal diversity within a language family corresponds to the original homeland. This is implemented in an algorithm which takes a lexicostatistically derived distance measure and a geographical distance measure and computes a lexical diversity measure for each language in the family relative to all the other related languages. The location of the language with the highest diversity measure is heuristically identified with the homeland.

On using qualitative lexicostatistics to illuminate language history: Some techniques and case studies
Author(s): Anthony P. Grantpp.: 277–300 (24)More LessFollowing certain aspects of the work on lexicostatistics carried out in the 1960s and published thereafter (Hooley 1971, Miller et al. 1971, Miller 1984) and thereby working in a tradition which has most recently been practised by Ringe et al. (1997, 2001), among others, I maintain that much of lasting value can be learned about linguistic interrelationships by using techniques which have been developed in work on qualitative (rather than merely quantitative) lexicostatistics, using character-based methods.

Beyond lexicostatistics: How to get more out of ‘word list’ comparisons
Author(s): Paul Heggartypp.: 301–324 (24)More LessThis article surveys various long-standing ambiguities and confusions that continue to dog lexicostatistics and glottochronology. I aim to offer some novel perspectives and clarifications, which also help map out how we might devise new, alternative methods to build upon the good in Swadesh’s troubled legacy. I challenge the recent trend towards honing down Swadesh’s original list to a minimal core. A richer signal on language relationships is to be had not by discarding the data in meanings considered ‘unstable’, but by exploring the revealing patterns that emerge only when those meanings are kept, and contrasted against their ‘core’ counterparts.

Phonetic comparison, varieties, and networks: Swadesh’s influence lives on here too
Author(s): Jennifer Sullivan and April McMahonpp.: 325–340 (16)More LessWhile his eponymous basic vocabulary lists and the study of language divergence may be Swadesh’s most appreciated legacies, we demonstrate that phonetic quantification of language varieties also follows very much in the tradition of Swadesh’s own work. We compare a few different measures of phonetic distance on a very small set of data from Germanic varieties, showing the influence of lexicostatistics and the relevance of Swadesh’s ‘Mesh Principle’. What we emphasise overall is that Swadesh’s influence is palpable, even in domains outside those for which he is best remembered.

A stochastic local search approach to language tree reconstruction
Author(s): Francesca Tria, Emanuele Caglioti, Vittorio Loreto and Andrea Pagnanipp.: 341–358 (18)More LessIn this paper we introduce a novel stochastic local search algorithm to reconstruct phylogenetic trees. We focus in particular on the reconstruction of language trees based on the comparison of the Swadesh lists of the recently compiled ASJP database. Starting from a generic tree configuration, our scheme stochastically explores the space of possible trees driven by the minimization of a pseudo-functional quantifying the violations of additivity of the distance matrix. As a consequence the resulting tree can be annotated with the values of the violations on each internal branch. The values of the deviations are strongly correlated with the stability of the internal edges; they are measured with a novel bootstrap procedure and displayed on the tree as an additional annotation. As a case study we considered the reconstruction of the Indo-European language tree. The results are quite encouraging, highlighting a potential new avenue to investigate the role of the deviations from additivity and check the reliability and consistency of the reconstructed trees.
