对鼻子形状不满意？这要怪气候咯

一个人鼻子的形状和大小总体上由遗传决定，但基因并非唯一原因。最新研究指出，气候条件同样在人类鼻子外形的演变过程中发挥着重要作用。

If you are not satisfied with the shape of your nose, blame it on climate, not your parents or grandparents.

对自己的鼻子形状不满意？不要怪父母或祖父母，怪气候吧。

In a study published this week in the journal PLOS Genetics, researchers from the Pennsylvania State University found that human noses may have been shaped, at least in part, by a long process of adaptation to local climate conditions.

美国宾夕法尼亚州立大学的研究人员发现，人类鼻子的形状至少部分是由当地气候长期塑造而形成的。这项研究本周发表在美国《科学公共图书馆•遗传学》杂志上。

Generally, wider noses are more common in warm and humid climates, while narrower noses are more common in cold and dry climates, it said.

大体上，温暖湿润地区的人鼻子较宽，而寒冷干燥地区的人鼻子较窄。

The findings were based on an examination of the size and shape of noses on people with West African, South Asian, East Asian, or Northern European ancestry.

研究人员分析了西非、南亚、东亚、和北欧血统的人鼻子的大小与形状。

The researchers looked at the width of the nostrils, the distance between nostrils, the height of the nose, nose ridge length, nose protrusion, external area of the nose and the area of the nostrils by using 3D facial imaging.
