Results of the chi-square test calculating the residuals, that is, the difference between the observed and the expected frequency of each combination of actor and adaptation role, are shown. Residuals below -2 and above 2 can be considered as contributing most to the significant result (P < 0.001) of the chi-square test. Positive residuals (green) indicate a higher observed frequency of an actorrole combination, and negative residuals (purple) indicate a lower-than-expected frequency. The size of the circles corresponds to the value of the residuals. 2 = 610.77, d.f. = 70, P < 0.001. See Supplementary Table 2 for a detailed overview of the results.
