Speechless, the ancient blood recognition was questioned, do you think there is a basis for the anci

No. There is no scientific basis for this method of "blood identification". Whether related or not, blood drips on the bones seep in. In ancient times, the blood recognition was a legend. The accurate determination of blood relationship can only be done through DNA identification.

"Identification of relatives by dropping blood" is an ancient test method, but according to the analysis of modern medicine, this method lacks scientific nature. However, due to the limitations of people's understanding and the lack of scientific means at that time, it was already remarkable for Song Tixing to apply blood to the practice of forensic inquest, and it was still an advanced method in the era in which Song Tixing lived.

According to the analysis of modern forensic science theory, the affinity and blood method of bone drop test lacks scientific basis. Whether the bones are kept in the open field or buried in the soil, after a long period of time, the soft tissues will be completely dissolved and disappeared through decay, and the hair, fingernails (toe) nails will fall off, and finally only the white ossified bones remain. The surface layer of the ossified bones is often corroded and crispy, and the blood of any person who drip it will infiltrate.

Founded during the Three Kingdoms, it has always been regarded as a guideline, and no one doubts it. It's a pity that it's unreliable. In ancient times, there were two methods of "dripping blood to recognize relatives".

One is called the drip bone method, and the other is called the blood method. As early as the Three Kingdoms period, there are examples of dripping the blood of a living person on the bones of a dead person to see if it penetrates, and if it can penetrate, it means that there is a blood relationship between parents, children, brothers, etc. The "Collection of Grievances" records:

The method of checking the bone is as follows: A is a father or mother, and there are bones, and B comes to recognize the biological male or female. Try to order a certain B to stab one or two points of blood on his body, and drop it on the bones, if he is his own, the blood will be soaked into the bones, otherwise it will not enter.

The vulgar cloud "drops bones", cover is also called this. It appeared in the Ming Dynasty around the time that when both parties were alive, the blood pricked out by the two was dropped in the vessel to see if it was condensed into one, and if it was condensed into one, it indicated that there was a parent-child brotherhood.

Just like blood transfusions must ask about blood type, people with blood type A will die after blood transfusion with blood type B, because blood of different blood types will be mixed together, and hemoglobin will clot and block blood vessels. When dripping blood to recognize relatives, if the blood of the two people clots into lumps, the two must not be related by blood. But then again, even if the blood of two people can be accommodated together, it does not prove that the blood type is the same or that they must be related.

So, the old people are half right.

No. The blood method is to drop the blood of two people in a vessel to see if the two drops of blood are fused together, if they are fused together, it shows that the two of them are related by blood, if not, then it means that they have no relationship between the two 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 dropped, and they will not fuse together; Conversely, if the water temperature is high, then the blood is very easy to disperse and look like it fuses together.

Methods of kinship identification used by modern science:

In modern science, paternity testing is generally used. According to reports, on December 31, 2002, when the reporter interviewed Dr. Gu Mingbo, the director of the genetic laboratory, in the DNA genetics room of the Criminal Technology Department of the Provincial Public Security Department, the consultation for paternity testing came in, and Director Gu Mingbo said that there was a consultation about doing paternity testing every day.

At present, due to the instability of social marital status, the increase in extramarital sex and the frequent occurrence of children born out of wedlock, the market demand for paternity testing is expanding day by day, and private appraisal agencies and intermediary agencies have emerged, and they attract entrusted appraisers at low prices. In China's current legal framework, the Supreme Court made the "Reply on the Issue of Whether the People's Court Can Use Human Leukocyte Antigen for Paternity Testing in Trial Work" on June 15, 1987. <>

No, because in ancient times they did not have the kinship problem between the direct relationship, so they used blood to identify relatives, thinking that those who are fused together are relatives, and those who can't be fused together are not relatives, this practice has no scientific basis, even if it is a kinship, blood may not be compatible.

There is no scientific basis for the ancient practice of dripping blood to recognize relatives. It's not just blood that is related to each other that will be combined, or modern paternity testing is more scientific.

No, there is a big bias in this practice, and it is impossible for blood of different blood types to be compatible, but not all children and parents have exactly the same blood type.

No, there is a very serious mistake in this practice, and the accuracy is very low, which is mainly related to the blood type.

Since the blood type of the child and the parent are often the same, the blood of the child and the parent will not coagulate. From this, it is considered to be a parent.

I don't think it's reliable to test the relationship between father and son and mother by blood. We all know that human blood types are divided into four blood types: A, B, O, and AB. With the exception of type O, which is compatible with the other three blood types, the other three blood types have a coagulation effect on blood types that are not their own.

The child's blood type is generally the same as that of the father or mother, with the exception of type AB. The father of blood type A and the mother of blood type B will give birth to a child with blood type AB, but the blood type of the child is not compatible with the parents.

Unreliable, this is the same as the paired blood type during a blood transfusion, as long as the blood mini-plate does not clot, it can be fused together.
