对鼻子形状不满意？这要怪气候咯

借助3D面部成像技术，研究人员观察了鼻孔宽度、鼻孔间距离、鼻子高度与鼻梁长度、鼻子突出程度、鼻子外部区域、和鼻孔区域等。

It showed that the width of the nostrils is strongly correlated with temperature and absolute humidity, but not the result of a random process called genetic drift.

结果显示，鼻孔宽度与被称为基因漂移的随机过程无关，而与温度和绝对湿度等气候特征强相关。

One purpose of the nose is to condition the air that we breathe, to ensure that it is warm and moist when it reaches the lungs, which helps to prevent infections.

鼻子的一个功能是调节吸入的空气，让空气在进入肺部时变得温暖、湿润，帮助预防感染。

The current study found the narrower nostrils seem to alter the airflow so that the mucous-covered inside of the nose can humidify and warm the air more efficiently.

目前的研究发现，窄鼻孔可以改变气流，因此分泌有粘液的鼻腔能够更有效地湿润和温暖吸入的空气。

"It was probably more essential to have this trait in cold and dry climates," it said.

研究报告写道：“这可能对干冷气候中的人们更重要。”

"People with narrower nostrils probably fared better and had more offspring than people with wider nostrils, in colder climates. This lead to a gradual decrease in nose width in populations living far away from the equator."
