Fig. 1: Global partitioning of ¹⁴C-dates into continental boxes.

The sometimes smaller extension of the boxes compared to the geographical boundaries of a continent reflect wide gaps in ¹⁴C-dated sites such as in South Asia. For Europe and western Anatolia, the focal study area, 15,089 archeological sites with 91,173 dates are shown as small brown circles. Subregions with independent reports of occupation density are approximated by green quadrangles (Tab. S4). Numbers indicate the locations of the 98 paleoclimate proxy sites (Tab. S2), and the yellow box the distribution of Northern Irish bogs used for the annual tree-ring reconstruction. Capital letters `NSWE' indicate the four cardinal directions.
