Correction

Two corrections have been made to the regional model of the Mesolithic–Neolithic transition in the central Mediterranean. These do not materially affect our results or interpretations, but we are issuing the correction for scientific accuracy and transparency.

Corrections:

• Radiocarbon uncertainties: In the regional radiocarbon database, the error from one date had been mistakenly propagated to others. These have now been corrected.

• Phase model boundaries: We had intended to use OxCal’s sigma boundaries throughout (as described in the main text of the published paper), but uniform boundaries were unintentionally used in all but one region. The corrected analysis now includes results from both approaches.

Impact:

• Corrected errors generally reduced variance in boundary estimates.

• Using sigma vs. uniform boundaries shifts estimated Neolithic start dates slightly later (to be expected given the nature of those boundaries and what they represent), but has no substantive effect on the overall results.

• Alternative classification of three ambiguous Sicilian samples (Mesolithic vs. Neolithic) also has negligible effect on the model outcomes.

In summary, the corrected models remain fully consistent with the published findings and with the broader consensus on the timing of the Neolithic transition in the region.
