Fig. 6

a The relationship between the classifications of the identified spider nrEVEs and their spider hosts. The thickness of link lines represented the number of targets of PIF-0. b The evolutionary timeline of spider nrEVEs and NALDVs is illustrated. Calibrated nodes are denoted by circles, while semi-transparent bars represent the 95% highest posterior density (HPD) of age estimates for the main clades. Age estimates and their 95% HPD intervals for the corresponding nodes are provided in Table 2. The branches are colored by the substitutions per site per million years (subs/Mya). The boxplot in the upper left corner shows the substitution rates difference from spider nrEVEs (n = 13) and NALDVs (n = 18). Statistical analysis was performed using two-tailed Student’s t-test. Boxplot boxes denote the interquartile range, middle lines indicate the median, and error bars indicate the min and max. The source data and P values were provided in Source Data file.
