A language tree is tested against a settlement chronology

Russell Gray and Fiona Jordan applied phylogenetic tree-building to Austronesian lexical data and compared the resulting branching order with the archaeological sequence of island settlement in the Pacific, reporting agreement with the rapid dispersal from Taiwan often called the express-train model. The significance for method is that two independent bodies of evidence — sound correspondences among living languages, and radiocarbon dates on pottery and settlement — were made to predict each other, which is the closest historical linguistics comes to an experimental test.

Historical — it happened, and the record is settled.

  1. Austronesian speakers move out of Taiwan
  2. Lapita voyagers enter Remote Oceania
  3. Dahl links Malagasy to Ma'anyan of southeastern Borneo
  4. Blust's Austronesian subgrouping places the deepest divisions in Taiwan

  7. Phylogeography puts the Indo-European homeland in Anatolia
  8. A dated phylogeny puts Sino-Tibetan at roughly seven thousand years
  9. A second phylogeny puts the same family at roughly six thousand years
  10. A hybrid model is proposed for the Indo-European origin
