Feeding red squirrels peanuts weakens their jaws and flattens their skulls, study finds.

A study shows that red squirrels in Britain, often fed peanuts by humans, develop weaker jaws and flatter skulls compared to wild squirrels. This change in anatomy, linked to easier-to-eat human-provided food, reduces their ability to crack nuts, essential for their diet. The findings suggest that supplementary diets should mimic natural food sources to maintain the squirrels' health and survival capabilities.
