Phylogenetic distribution of life history and morphological traits (maximum lifespan potential, relative brain size, body mass, gestation time and age at sexual maturity) in mammals. A phylogenetic tree for 46 mammal species with fully sequenced genomes is shown. Bars show the relative value of each variable, including log10 values of maximum lifespan potential (MLSP, green), relative brain size (orange), body mass (purple), gestation time (pink), and age at sexual maturity (blue). See Supplementary Table 1 for raw data and silhouette species names.
