研究发现,喂养红松鼠的花生会削弱他们的下巴 扁扁他们的头骨 Feeding red squirrels peanuts weakens their jaws and flattens their skulls, study finds.

一项研究表明,英国的红松鼠通常由人类喂养花生,与野生松鼠相比,他们的下巴和头骨较弱。 A study shows that red squirrels in Britain, often fed peanuts by humans, develop weaker jaws and flatter skulls compared to wild squirrels. 解剖学的这一变化与较容易吃的人类提供的食品相关联,降低了他们断裂坚果的能力,而坚果对于他们的饮食是必不可少的。 This change in anatomy, linked to easier-to-eat human-provided food, reduces their ability to crack nuts, essential for their diet. 调查结果表明,补充饮食应模仿天然食物来源,以维持松鼠的健康和生存能力。 The findings suggest that supplementary diets should mimic natural food sources to maintain the squirrels' health and survival capabilities.
