With the application of phylogenetic methods to model the history of the evolution of languages, such speciation events are given elegant timescales that may be used to explore what causes the emergence/divergence of languages.

A Full-Scale Test of the Language Farming Dispersal Hypothesis
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.

Some of the nongenetics chapters strongly support the FLDH. Jones’s chapter reviews the origins of domesticates that constitute the agricultural/pastoral packages associated with farming/language dispersals. Cattle travel with wheat and barley, and that happy union strengthens the dispersal potential of those grains; pigs serve that function for rice, though less effectively, since pigs cannot pull a plow. Harris’s chapter in part II compares the expansion capacities of early agriculture in five areas of the world, concluding that the evidence supports the FLDH for an Indo-European expansion better than for expansion of any of the other four centers of farming. This is supported by the chapter by Bar-Yosef, which outlines the transformation of the Natufian society in the northern Levant into Neolithic farmers, the chapter by Hassan, which identifies cognate words for food production and cattle keeping in African languages, and the chapter by Militarev, which presents an extensive list of etymologies consistent with the hypothesis that the Natufians spoke proto-Afrasian.
In Examining the Farming/Language Dispersal Hypothesis, P
This book emerged from a conference of scholars from three different disciplines (archaeology, genetics, and comparative linguistics) that was convened by the book’s coeditors. A total of 36 papers written by 43 delegates were circulated before final drafts were prepared, and all the papers focused on the farming/language dispersal hypothesis (FLDH)—namely, that the distributions of some language families resulted from expansions of farming practices from their points of origin. Bellwood introduced the term “triangulation” to refer to the simultaneous focus of evidence from all three disciplines on the hypothesis. The book’s 36 chapters are organized into three parts, the first of which consists of only two chapters—each written by one of the book’s coeditors—that introduce the rationale and assumptions underlying the FLDH.

muralis are consistent with 'Darwin's wind dispersal hypothesis' that high cost of dispersal may select for lower dispersal ability in fragmented landscapes, as well as with the 'leading edge hypothesis' that most recently colonized populations harbour more dispersive phenotypes.
