Larger Mammalian Body Size Leads to Lower Retroviral Activity

Figure 2

(a) Correlation between ERV count and body mass for the number of ERV integrations acquired over the last 10 my.

(b) Correlation between mean age of all ERV integrations and body mass from the genomes of 38 mammals. Body mass is log-transformed, and the mean ages are calculated correcting for the substitution rate. We have not taken into account the effect of body size on substitution rate in calculating the ages.
