There was only a small difference between Neanderthals and chimpanzees in the genes they had in each of the three networks; the difference was weakly significant for each of the networks if the samples are considered correlated ( Tukey’s HSD test , p < 0.05) and insignificant for the emotional reactivity network if the samples are independent (Table 2 , Supplementary Table S8 ).
