Why do my little toenails have two lobes?

First, take off your shoes and socks and look at your little toe. Are the nails on it one-lobed or two-lobed?

Why do toenails split into two parts? Let's uncover this mystery together today.

Why do little toenails split?

Split toenails are medically called scalloped nails, also called little toe complexion.

Some people have it on one foot, and some people have it on both feet; some people have it in two parts, and some people even have it in three parts; some people have it when they are born, and some people only appear when they grow up.

So, why does it split? There are two legends:

It is said that having two little toenails means that you are a descendant of pure Han people.

I also heard that more than 640 years ago, the imperial court moved Shanxi people to the Central Plains in order to populate the Henan, Shandong, and Hebei regions. Before being "issued", soldiers also cut off their little toenails, causing cracks that were passed down from generation to generation.

Is the little toenail split into two parts an immigrant from Shanxi?

Many people think this statement is funny. The knife that was cut back then was a traumatic injury. Besides, more than 600 years later, how could it be passed down from generation to generation to this day? Don't tell me, investigations have proven that this is really related to Shanxi immigrants.

In 2005, associate professor Bian Jianchao and graduate student Hao Weiguo of Fudan University conducted inspections and research on genetics.

Through a survey of the seven provinces of Shanxi, Shaanxi, Henan, Jiangsu, Zhejiang, Jiangxi, and Fujian, it was found that starting from Shanxi, the proportion of petal nail owners showed a decreasing trend toward the southeast. , which is consistent with the historical facts of immigration.

Has the little toenail divided into two parts mean that the Han race is purebred?

This is narcissistic thinking. In fact, petal-like nails are not a unique sexual characteristic of the Han people. Not every Han people have them, and not all people with petal-like nails are Han people. Instead, they may be the product of ethnic integration.

After all, not all immigrants back then were Han Chinese. Before the large-scale immigration in Shanxi, people already lived in a mixed state. Among the immigrants were Han people, Mongolian nobles, Semu people, Sinicized Hu people, etc. It is very unrealistic to distinguish purebred Han people.

Researchers from Fudan University speculate that the long petal-like nails may be the result of the toe mutation caused by friction among the ancient Chinese people when they worked without wearing shoes, and became a gene that has been retained to this day; it may also be the result of the integration of ethnic groups. produced physiological characteristics.

In other words, no matter which possibility it is, it is just a physiological characteristic. Whether it is present or not, it will not be beneficial or harmful to health. As long as it lasts, it will be safe.
