Mutation rates per generation (A) and per year (B) for multicellular species with sufficient data available. Per‐year rates were calculated using a reported age, an estimate of generation time, or an average of two estimates of generation time (raw data and references in Table S2). For the trees (Prunus, Picea, and Quercus), the mutation rates were estimated in exceptionally long‐lived specimens; for Picea, the lower per‐year mutation rate is our estimate for P. sitchensis and the higher per‐year mutation rate is the average neutral substitution rate for P. glauca, P. sitchensis, and P. abies (De La Torre et al. 2017). Error bars represent the Poisson confidence intervals.
