Bonobo and chimpanzee gestures overlap extensively in meaning

Fig 8

The probability of generating randomised gesture matrices that are more similar than those observed when a random subset of available gestures is used (S1 and S2 Data).

Each line corresponds to 1 of the 4 different matrix randomisation constraints: preservation of the number of gestures assigned to each ASO and the number of ASOs assigned to each gesture (Row & Col. Sum Pres., orange), 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 unconstrained randomisation of assignments (No Constraints, grey). ASO, Apparently Satisfactory Outcome.
