A dated phylogeny puts Sino-Tibetan at roughly seven thousand years
Sagart and colleagues published a dated phylogeny of Sino-Tibetan based on a curated cognate dataset, obtaining a root age of the order of seven thousand years before present and associating the family's origin with early millet agriculture in northern China. The date is materially older than that reported by a second phylogenetic study of the same family published in the same year.
Historical — it happened, and the record is settled.

Dated language phylogenies shed light on the ancestry of Sino-Tibetan
Supports the reported Sino-Tibetan root age of the order of seven thousand years before present and the association with northern Chinese millet agriculture. V55 verification basis: this session had no access to any source — WebFetch was egress-blocked for every host attempted and the WebSearch budget was exhausted before authoring — so the cited work was not retrieved, and no page, volume or figure quoted from it was re-checked. The age is given as an order of magnitude, not as the paper's point estimate or interval; volume from standing knowledge, page range omitted rather than guessed.
