Bonobo and chimpanzee gestures overlap extensively in meaning

The frequencies of the total number of matches between species gesture matrices achieved by 10,000 iterations of the permutation test using 4 different constraints on matrix permutation (S1 and S2 Data).

From bottom to top: unconstrained randomisation of assignments (No Constraints, grey), preservation of only the number of ASOs assigned to each gesture (Row Sum Pres., yellow), preservation of only the number of gestures assigned to each ASO (Col. Sum Pres., purple), and preservation of the number of gestures assigned to each ASO and the number of ASOs assigned to each gesture (Row & Col. Sum Pres., orange). The total number of matches in the original gesture matrices is given by the red vertical line. ASO, Apparently Satisfactory Outcome.
