  1. ‘Leapers’ include small, vertical-clinging-and-leaping prosimians (galagos and tarsiers); ‘Prosimians’ and ‘Primates’ exclude galagos and tarsiers; ‘Mammals’ refer to non-primate eutherians (artiodactyls, perissodactyls and proboscideans excluded). Only extant species have been included in the regressions
  2. BM body mass (in g), ACL distal calcaneal length (in mm), TCL total calcaneal length (in mm), N = sample size, r = correlation coefficient, SEE standard error of estimate, p significance, CI confidence interval
