Summed probability curves for a refined set of Class 1 dates (with cutoffs based on island-specific 14C datasets) compared with original Class 1 curves (1) with a broader range of dates to 300 B.P.; examples include all localities that had 10 or more Class 1 dates in ref. .

Fig. 2.
Cumulative probability distributions of Class 1 dates with the upper limit of certain colonization varied to show alternative probable colonization outcomes that could be defined based on more restricted summed probability curves; examples include all island groups with 10 or more Class 1 dates. Cumulative probability curves are calculated with the upper limits as set by ref. as well as set at both 50 and 100 y earlier. The Late Age Estimation Model (LAEM), which reflects the “latest likely date for colonization” (1), is noted where each cumulative probability curve intersects the x axis at 50% probability.
