The shape of human nose has evolved into the most suitable shape in order to adapt to the natural environment in their respective regions.

according to a paper published in June 216 in American Journal of Physical Anthropology by researchers at the University of North Texas, people who live in high latitudes such as northern Europe have taller and slimmer noses. On the contrary, people living near the equator have flatter noses.

The temperature and humidity in various areas, that is, the natural environment, have a great influence on the shape of the nose.

The differences between different races are as follows:

1. The width of the nose root, from wide to narrow, is black, yellow and white.

2. The height of the bridge of the nose: white people are the highest, yellow people are in the middle, and black people are the lowest.

3. The size and roundness of the tip of the nose: the largest one is black, the yellow one is in the middle, and the white one is the smallest.

4. The width of nose wing: Black is the largest, followed by yellow and white.

5. Nose-lip angle, that is, the angle between nose and upper lip: white people are the smallest, followed by yellow people and black people.

It can be seen that the shape of the nose varies greatly with different races. Anthropologists use this as the basis for racial classification, and individual differences and group differences in the same race are also great. For example, among the Han ethnic groups in China, the noses of southerners and northerners are very different.
