Handedness and the Oldowan tool industry: Is preferential right-handedness a relic from our evolutionary past?

Although there is literature on psychological, anthropological, and biological reasons for global preferential right-handedness, there has yet to be literature studying the connection among these three disciplines. The goal of this pilot study is to shed light on the correlation of handedness and Oldowan tool manufacturing in order to provide direction for future study. By taking a cross-disciplinary perspective on evolutionary advantages, genetics, and brain lateralization, it is believed researchers may be able to understand why 90% of the human population is preferentially right-handed. This study concludes that there is a correlation between handedness and toolmaking efficiency, and that further exploration is needed into the relationship of handedness and Oldowan tool production
