A second phylogeny puts the same family at roughly six thousand years
Zhang and colleagues published a phylogenetic analysis of Sino-Tibetan in the same year, likewise locating the origin in northern China but obtaining a root age of the order of six thousand years before present, roughly a millennium younger than the other study. The two results agree on geography and disagree on chronology by an interval longer than most of recorded history, on the same family, using nominally similar methods and different datasets and calibrations. The disagreement is recorded here as it stands rather than adjudicated.
Uncertain — sources disagree, or the dating is contested. Stated here, not resolved.

Phylogenetic evidence for Sino-Tibetan origin in northern China in the Late Neolithic
Supports the reported Sino-Tibetan root age of the order of six thousand years before present, roughly a millennium younger than the companion study of the same year, on the same family. 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; volume from standing knowledge, page range omitted rather than guessed.
