Recent attention has focussed on the question of localising the Austroasiatic homeland, especially interdisciplinary inquiries seeking correlations between linguistics, genetics, and archaeology. Among the various suggestions that have been offered over the years, one can distinguish three broad lines of inquiry:
1. a western origin, in eastern India or about the Bay of Bengal,
2. a northern origin, in central or southern China, and
3. a central origin, within Southeast Asia
Interestingly, the last of these is the least popular hypothesis. Consequently specialists are in the position of having to find arguments in support of a homeland in locations where little or none on the diversity of the Austroasiatic phylum is found today.
Instead, Dr. Sidwell suggest that the marked geographical clustering of Austroasiatic languages along the course of the Mekong river indicates that proto-Austroasiatic speakers inhabited a riverine corridor overlapping modern NE Thailand and Southern Laos, from which they radiated in NW and SW trajectories. The evidence of proto-Austroasiatic lexicon, and the internal phylogeny of Austroasiatic, is consistent with this claim.
