In addition to blood to recognize relatives, what other methods did ancient people use to recognize

There is no scientific basis for blood recognition in ancient times.

The method of blood recognition was founded in the Three Kingdoms period and has always been recognized by the ancients as the only way to recognize relatives. In ancient times, there were two methods of dripping blood to identify relatives, one was the blood method and the other was the bone dripping method.

1. Combined blood method.

If they are fused together, it means that they are related by blood, and if not, then it means that they are not related by blood.

In fact, there is no scientific basis for this method, because the temperature of the water can control whether the two drops of blood can be fused together, if the temperature is low, the two drops of blood will quickly coagulate when they are dripped in, and they will not melt together; Conversely, if the water temperature is high, then the blood is very easy to disperse and look like it fuses together.

2. Drip bone method.

If only bones are left after a person dies, the way to tell if he is a relative is to drop blood on his bones, and if the bones absorb the blood, then they are related to each other, and if the blood passes through the bones, then they have no relationship.

In fact, whether the bone is in the open air or buried in the soil, its soft tissues will decay and then dissolve and disappear, and the surface of the bone will become decayed and crispy, and no matter what liquid can penetrate into it, so the bone drip method is not scientific.

At present, if you want to know whether the child is changing your or the king next door, you will directly use DNA identification.

In film and television dramas, if you want to verify whether the two are related, then these two people must cut their fingers and let the blood stains of the two people in a bowl of cold water to see if they will merge together. If you merge, you feel that there is a kinship, but on the contrary, you don't. This kind of method seems very simple, and it is much easier than the current DNA, so is it really reliable?

If it's reliable, why isn't it needed to test for kinship now? The problem may be a blanket no. It is important to understand that regardless of whether the two people to be examined are related or not, people's skin can be coagulated.

It's just that the timing of the union is different. Therefore, what the ancients called blood recognition, in short, is only a subjective discrimination of them, which not only has no basis, but is also particularly unreliable. In modern society, due to the complexity of everyone's social connection, sometimes they can't tell who the child is, <>

I had no choice but to seek the assistance of a designated medical institution. In fact, this kind of situation has been happening since ancient times. In ancient times, if people wanted to clarify their own family history, they would generally use the method of blood identification to carry out identification.

In fact, there is no scientific evidence for such methods, and the results obtained are not precise. But in ancient times, people did not understand this, so they believed in this kind of method. Friends, remember, but don't be deceived by film and television dramas anymore, and don't believe in such unfounded methods, or believe in contemporary scientific and technological progress.

Particularly reliable. In ancient times, it was verified in this way, which shows that this method is very effective.

There is no scientific basis for this, and the way of identifying relatives is a wrong way, which is influenced by a variety of circumstances, and the results are not correct. The ancients generally recognized their relatives by dropping blood, comparing their appearances, and checking the eight characters of their birthdays.

It's just a very ridiculous way to recognize relatives, there is no scientific basis for it, and anyone's blood will fuse together. They will recognize their relatives by dripping blood, but this way of recognizing relatives is very unscientific and unreasonable, which will cause a lot of misunderstandings.

There is no scientific basis for the ancient blood recognition; The ancients used blood to recognize relatives, bones to recognize relatives, and reasoning methods to recognize relatives.

In ancient times, the principle of blood recognition is to indicate the existence of blood relationship between the two people through the fusion of blood or whether the blood can penetrate into the bones, but there is no scientific basis for this practice, using the method of "blood recognition", the blood will seep into the bones or fused together. To check whether there is a blood relationship between parents and children, DNA testing techniques can be used.

What is the principle of blood recognition in ancient times?

In some ancient TV series, you can often see the bridge of blood recognition, and its principle is that if the blood of two people can be fused, it means that the two are related, but in fact, there is no scientific basis for this practice, and most of the results are not credible.

In ancient times, there were two ways to recognize relatives by dropping blood, one was the bone dropping method, and the other was the blood combination method, the bone dropping method was to drop the blood of the living person on the bones of the dead person, and the blood method was to drop the blood of two people into the vessel together to see if it was compatible. However, according to modern science, the blood seeps into the bones or fuses together, regardless of whether they are related or not.

Generally speaking, whether the bones are stored in the open air or buried in the soil, the soft tissues will decay and disappear, and without the protection of the soft tissues, the surface of the bones will corrode and crispy, and at this time, blood or water can drip in. The blood method is also unreliable, there is water in the blood, no matter whether the two people are related by blood or not, as long as they are put together, they will be blended soon, and they don't have to be flesh and blood.

Modern DAN paternity testing techniques

As long as the blood, hair, saliva, bones, etc. of people are collected for comparison, they can be judged by genes whether there is a blood relationship between parents and children, and the examination results are authoritative and accurate, which is the most effective method for identifying parent-child relationships.

Because the "blood drop" is often dripped into clear water, red blood cells will cause the cell membrane to rupture due to osmotic pressure, and usually two drops of blood with different blood types will not precipitate. There is no scientific basis for this method, and the ancient method of determining paternity is recorded in the forensic works of the Song Dynasty in China. <
