Another article taking the 'genetic/evolution' metaphor of language
change literally has been published, this time in Nature. There is a

ABSTRACT

Languages, like genes, provide vital clues about human history. The origin
of the Indo-European language family is "the most intensively studied, yet
still most recalcitrant, problem of historical linguistics". Numerous
genetic studies of Indo-European origins have also produced inconclusive
results. Here we analyse linguistic data using computational methods
derived from evolutionary biology. We test two theories of Indo-European
origin: the 'Kurgan expansion' and the 'Anatolian farming' hypotheses. The
Kurgan theory centres on possible archaeological evidence for an expansion
into Europe and the Near East by Kurgan horsemen beginning in the sixth
millennium BP. In contrast, the Anatolian theory claims that Indo-European
languages expanded with the spread of agriculture from Anatolia around
8,000-9,500 years BP. In striking agreement with the Anatolian hypothesis,
our analysis of a matrix of 87 languages with 2,449 lexical items produced
an estimated age range for the initial Indo-European divergence of between
7,800 and 9,800 years BP. These results were robust to changes in coding
procedures, calibration points, rooting of the trees and priors in the
bayesian analysis.
