Comparison between null model of cultural diffusion predicted by IBD (folktale ∼ geographic) and alternative models [i.e., demic diffusion (folktale ∼ genetic), cultural diffusion biased by linguistic barriers (folktaleL ∼ geographic), and demic diffusion biased by linguistic barriers (folktaleL ∼ geneticL)]. Values refer to Pearson’s product–moment correlation (cor) and bias-corrected distance correlation (bcdCor) after Bonferroni correction.
