Study links human right-handedness to upright walking and bigger brains
Key Takeaways
- 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.
- The findings suggest right-hand bias likely strengthened gradually across human evolution rather than arising from a single cause.
