Key Takeaways
- A University at Buffalo study argues the human chin is not an adaptation but a structural byproduct of facial evolution
- Researchers tested and supported the null hypothesis that the chin arose through neutral evolutionary processes
- Comparative analysis across apes and humans found no evidence that natural selection specifically shaped the chin
