Why do the little toenails have two petals? Is this a sign of descendants of the tribe?

Goodbye, people with two-petal little toenails are "diseased", and it is not a unique sign of descendants of any ethnic group. It is called "petal-like nails" in medicine, and Western medicine calls it It is called "Lister's corn", and our ancestors called it "crotch toe". As for "pure descendants of the Han people" and "descendants of the Xianbei people", it is an unscientific misunderstanding, just like the ancient "blood recognition". An untenable conclusion. 01. The legend of the pure Han people - Hongdong Big Locust Tree Immigration

Let’s first talk about this pure Han people’s story. Its background story originated in the early years of the Ming Dynasty. Due to the continuous wars and many wastes to be built, Zhu Yuanzhang decided to To replenish the population in the Central Plains, people from Shanxi were gathered and transferred to various locations in batches.

The ideological concept accepted by our country since ancient times is that "fallen leaves return to their roots and souls return to their homeland." If it is not an important matter, people will not leave their hometown. Since Zhu Yuanzhang personally ordered it, these relocated people gathered under the large locust tree in Hongdong County, Shanxi Province, and then split their little toenails in half with a knife to identify themselves.

The amazing thing is that the offspring of these people also have two-petal little toenails, so there is a legend that "people with two-petal little toenails are pure Han people".

Let’s analyze this legend. The “Hongdong Big Locust Tree Migration” is indeed true. It happened from 1370 to 1417 AD. At least half of a family had to migrate out. Those who are willing will naturally be given compensation and travel expenses, while those who are unwilling will be forcibly bound and escorted there, and many will have to endure the pain of having their wives and children separated.

There is a very clear record of migration in "Records of Taizu of the Ming Dynasty":

In November of the 22nd year of Hongwu (1389), "The above is based on Zhangde, Wei Hui, Henan, In places like Guide, Linqing and Dongchang in Shandong, the soil is suitable for mulberry and jujube, and the people are few but the land is favorable. The people in Shanxi are in a narrow land, so they are often poor. Therefore, Li Ke, the governor of the rear army, and others were ordered to tell the people that they were willing to move. Those who have taken possession of more land will be punished by false pretense, and the Ministry of Industry and Commerce will order them back."

In order to verify their identity, these migrants used a knife to split their little toenails into two pieces. Of course. It is also said that the escorting officers and soldiers ordered them to split their little toenails into two pieces and use them as marks to identify themselves and prevent them from escaping quietly on the road.

No matter what the reason is, there is a saying among the descendants of these Shanxi people: "Who is the immigrant from the ancient Sophora japonica? Take off your little toe to check the nail shape."

However, this kind of man-made trauma cannot be expressed in future generations through genetic means. This legend is an exaggeration of reality. 02. The legend of the descendants of the Xianbei people - Li Tang Dynasty

As for the legend of the descendants of the Xianbei people, its background story is that in the earlier Tang Dynasty, Emperor Taizong Li Shimin discovered that his toes were special and small. The toenails are actually two pieces. He believes that this characteristic of his may be inherited from his mother and grandmother. After all, the same is true for his grandmother Dugu and his mother Queen Dou, both of whom share the same identity as Xianbei people.

Li Shimin also took the opportunity to investigate all the people in the palace and found that most of the people's little toenails have two petals, so there is a saying that "the little toenails of the descendants of the Xianbei people have two petals".

However, some scientific researchers analyzed 721 Uyghurs in detail and concluded that their probability of developing petal nails is 51.15%, and Han people also have a 58.97% probability. Even countries such as Portugal, Germany and Switzerland There are also cases of flap nails.

Are they all descendants of the Xianbei people? Obviously this statement is untenable. Otherwise, by relying on this method of recognizing ancestors, we might be able to identify Europeans. 03. The truth about scalloped nails - an autosomal dominant trait

Floped nails are not caused by trauma in one generation. Instead, people in ancient times were affected by the environment when working, and the little toenails often rubbed against each other. , and it took many generations to adapt to changes before genetic inheritance emerged. To be precise, it is an autosomal dominant trait and has nothing to do with ethnicity.

In order to draw this conclusion, scientific researchers went to the central area of ??Hongdong County, Shanxi Province to investigate 27 core family pedigrees (one of which had a complete three-generation relationship). The results were:

The frequency of flap nails is 79.51%, of which 82.28% are men and 76.15% are women.

In other words, this hereditary trait is more obvious in the local area, but not 100% of people have it. Some people only develop flap nails when they are 5 years old. If this identification method is followed, many people will have to Being kicked out of the family tree, outsiders or foreigners may become their descendants. 04. Identifying relatives by dripping blood - the same cannot identify genetic relationships

Untrustworthy with the above identification statement is "identifying relatives by dripping blood". This method was an authoritative identification method in ancient times. "Washing" There are detailed records in "Collection of Injustices" and "Southern History". It is also reflected in the costume palace dramas we watch, as well as in the comedy "Nine-grade Sesame Official" starring Stephen Chow and "The Punisher of the Song Dynasty" starring He Bing. There are also special plot expressions.

In fact, the bone dripping method and the blood combining method are very unscientific. As long as the surface of the bone is crispy, most liquids can drip in, let alone human blood. You can add dog blood, mineral water, and urine. Going in has the same effect.

The same principle applies to the method of combining blood. As long as two drops of blood are put together, no matter whether the owners are related by blood or whether their blood types are the same, the result will inevitably be fusion.

If you put 2 drops of blood in the water, they will naturally melt in the water, and then melt together, and the whole water will turn light red.

If you want the blood to fuse quickly, you can warm the vessel in advance, so that when two drops of unrelated blood are put together, they will quickly merge into one. If you travel to ancient times, you can use this to identify a "good father". It is too dangerous to be the prince of an emperor, so at least you can identify a prince as your father. The ancients would not question the reliability of blood recognition.

Of course, if modern people want to identify their ancestors or check their blood relationships, they don’t need to get little toenails or blood bones. They can get it clear by doing a DNA test.
