  • Exact permutational tests were used to test the null hypothesis of homogeneity. Categories that were affected by ambiguities in the networks are indicated by a number followed by a second number in parentheses. The first number is the count under resolutions Ia and Ib for humans and chimpanzees, respectively, and the number in parentheses is the count under resolutions IIa and IIb. The probability levels are presented in the same manner, with the first probability referring to resolution I and the probability in parentheses referring to resolution II.
