All p-values corresponds to HSD Tukey post-hoc comparisons, except for the ones from the L. Copper Age samples (Mann-Whitney U test; in italics), as they do not follow a normal distribution (S3 Table). N = 199; E. Neolithic: n = 2; E. Neolithic: n = 14; M. Neolithic: n = 71; L. Neolithic: n = 47; E. Copper Age: n = 26; M. Copper Age: n = 20; L. Copper Age: n = 3; E. Bronze Age: n = 2; L. Bronze Age: n = 11; E. Iron Age: n = 3. Values represent p-values (p<0.05 in bold).

*Early Neolithic samples from the Tiszaszőlős-Domaháza site were treated separately for comparison.
