Abstract

Explaining the transition from nonhuman to human behavior is a major scientific problem. Penn et al. argue for discontinuous evolution; they review many relevant papers but miss some that disagree with their stance. Given the shifting ground on which Penn et al.'s theories are based, and the likelihood of future studies providing additional information on continuities, a more open approach to continuity is warranted.
