Optimization through lateralization: The evolution of handedness

Research output: Contribution to journalArticlepeer-review

12 Scopus citations


The target article proposes that behavioral asymmetries evolved in response to social pressures, accounting for the unequal distribution of handedness across the population. In contrast, we provide evidence that human handedness reflects individual adaptations that enhance movement skill, and that the distribution across the population is best explained by a genetic polymorphism, either balanced or tending toward fixation for right-handedness.
