What about two little toenails? What is the legend about petal nails?

Today, the school easy search prepared for everyone: What happened to these little toenails? Interested friends please come and have a look!

Speaking of this fact, Han is indeed controversial. People always say that, that is, it is always controversial anyway. Recently, Bian Xiao wanted to talk about a controversial topic for a long time. Some people say how to tell whether this Korean is pure or not? Just look at one place, that is, whether their little toenails have two petals. Don't think that this was invented by Bian Xiao. There is a lot of controversy on the internet. So today we will use a scientific method to explain why this little toenail has two petals. Interested people can have a look!

If we look closely, we will find that many friends have two little toenails like this.

When we were young and ignorant, we used to think that two little toenails were "abnormal" and even had the experience of tearing them off.

Is this a characteristic of aliens? Does this mean that there is something wrong with the body?

1. Legend of the origin of Cladocera

Who were the ancient Huai 'an immigrants? "Take off their little toes and test their armor."

This is a popular folk song, which is also related to the origin of the legendary cladocera. It is said that frequent wars at the end of Yuan Dynasty and the beginning of Ming Dynasty led to the loss of wasteland and human settlements in Henan, Hebei and Shandong.

In order to improve this situation, the Ming Dynasty decided to practice "reclaiming wasteland". After decades of forced migration, a large number of Shanxi people were moved to the Central Plains.

According to legend, Shanxi people who were forced to migrate in those years gathered under a big locust tree in Hongtong County. The soldiers in charge of escorting them cut a knife on everyone's little toe as a sign that the descendants of immigrants in Hongtong County, Shanxi Province recognized each other and found their roots.

This has also become the origin of the most widely circulated petal nail.

Of course, legends belong to legends. We just need to treat it as an interesting story. After all, the scar left by the knife wound on the little toe can't be inherited through DNA.

However, a research data from Fudan University shows that petal-shaped nails are indeed related to Shanxi. In the population distribution map of petaloid beetles, the proportion from Shanxi to southeast is indeed decreasing. In addition, petal-shaped nails are dominant inheritance, which is very common in Han population.

This also reflects that the distribution of cladocera is related to the migration of ancient populations.

2. The truth of sheet armor

In fact, it's nothing special that two people have small toenails. In medicine, it has a technical term called "petal nail".

According to domestic research data, at least 60% people in China have two little toenails. In other words, many people in China have petal-shaped armor.

Of course, we can't regard Cladocera as a symbol of a nation, because experts speculate that Cladocera is actually very common in East Asia, but it may have originated from some genetic mutations of China ancestors. Because of its dominant inheritance, Cladocera was still well preserved in the subsequent ethnic integration in China. It also means that people of every nationality may have petal-shaped armor.

Therefore, whether you are in front of the screen or not, you are a member of the Chinese nation.

4. Cold knowledge

Back to the beginning of the article, are cladocera the characteristics of aliens? Can it predict diseases?

Of course not. Clavicular nail is just a common physiological phenomenon. It will not endanger everyone's health, nor will it have any impact on the body. Let's look at it with a normal heart.

What's the use of having little toenails on your little toes? It's no use. Nobody needs to tear anything up. It would be bad if the wound was infected.
