Partial distance correlation at a global scale

Model	pdCor	P
Folktale $\sim$ genetic, geographic	-0.11	1.00
Folktale $\sim$ geographic, genetic	0.26	<0.001
FolktaleL $\sim$ geneticL, geographic	0.17	<0.001
FolktaleL $\sim$ geographic, geneticL	0.25	<0.001

Results of partial distance correlation for null (folktale ∼ geographic, genetic) and alternative models [i.e., demic diffusion (folktale ∼ genetic, geographic), cultural diffusion biased by linguistic barriers (folktaleL ∼ geographic, geneticL), and demic diffusion biased by linguistic barriers (folktaleL ∼ geneticL, geographic)] after Bonferroni correction.
