Study links human right-handedness to upright walking and bigger brains
A comparative primate study led by University of Oxford researchers suggests humanity’s overwhelming right-handedness may be best explained by two evolutionary shifts: bipedalism and larger brains.
- Researchers analyzed handedness-related data across 41 species of monkeys and apes.
- The study found that larger brains and anatomy associated with upright walking best explain humanity’s overwhelming right-handedness.
