The passage around this formula
…following year, using Eric Charnov’s dimensionless framework for comparing life-history variables across mammal species. Their comparison of fertility-rate parameters is precise: the annual birth-rate parameter they call b is 0.142 for humans against a range of 0.063 to 0.126 across the great apes they compare against, and the product of age at maturity and that fertility rate, b , comes out to 2.05 for humans against 0.46 to 0.79 for apes [ 1 ] . Humans combine a maturation schedule that, on Charnov’s…
