Rushton’s (1989) response failed to address many of my criticisms, cited the relevant literature in a biased manner, and misrepresented both theory and data. His hypothesis about race differences on the r/K continuum should be rejected on the grounds that (a) the differences between r and K selection have little effect on larger mammals like man; (b) the literature reviews supporting this hypothesis are biased and many nonsupportive studies exist; (c) the hypothesis’s assumption that the claimed race differences are functionally related to reproduction is implausible and unsupported; and (d) the race differences predicted by this hypothesis can be explained by environmental causes.
