- Enamel nanocrystal misorientation increased with meat-eating and agriculture
A study published in Nature found that enamel nanocrystal misorientation in primate and human teeth increased with harder diets, such as meat-eating and agriculture, suggesting misorientation enhances enamel resilience during dietary shifts in human evolution.
- Nanostructure of tooth enamel casts light on dietary shifts as humans evolved
The nanostructure of tooth enamel in primates, hominins, and modern humans changed as their diets evolved. The arrangement of mineral nanocrystals in enamel reflects dietary shifts during species evolution.
