Where the article explains it
where w is body weight and A is a taxon-specific growth constant; most mammals run at a constant of about 1, but “the mean primate value for A is about 0.4” [ 3 ] .
The passage around this formula
where w is body weight and A is a taxon-specific growth constant; most mammals run at a constant of about 1, but “the mean primate value for A is about 0.4” [ 3 ] . Primates grow slowly relative to other mammals of the same size to begin with, and humans, on the same equation, grow slower still during middle childhood than…
