Strong correlation between longevity and developmental traits in mammalian families. A Correlation between maximum adult lifespan and age at sexual maturity (r2 = 0.788). B Correlation between maximum adult lifespan and gestation time (r2 = 0.748); monotremes, the only egg-laying clade of mammals, are an outlier. C Correlation between maximum adult lifespan and weaning age (r2 = 0.749). Only families with at least three species are shown (n = 22). Maximum adult lifespan = maximum lifespan minus age at sexual maturity. Data from AnAge build 14 [15]. Silhouettes from phylopic.org
