Correlation of genetic distances with relevant variables.

Variable	Simple Mantel test: R (P value)	Partial Mantel test: P value
Geography	1.90E – 01 (2.00E – 04)	1.83E – 02
Diet/technology	6.62E – 02 (4.00E – 04)	9.75E – 01
Language	2.32E – 01 (<1E – 4)	4.00E – 04
Time	2.31E – 02 (<1E – 4)	2.58E – 01

P values are based on 10,000 permutations. Multiple R² for partial Mantel test: R² = 0.30931.
