The scientific basis of fingerprint fortune telling is

Is there any scientific basis for palmprint?

There is scientific basis for palmprint to see a doctor, but there is no scientific basis for fortune telling.

Face, palm print, fingerprint and blood type are all genetic products. The face will be aged, damaged and changed due to surgery, but the dermatoglyphics and blood type will remain unchanged for life. Because of this, in ancient times, people used fingerprints and palm prints as evidence to conclude a contract, while in modern times, people used them as a means of investigation.

Dermatoglyphics and fingerprints are related to diseases caused by chromosome aberration. For example, an important symptom of congenital stupidity is the "customs clearance hand", and in the usual saying, the "customs clearance hand" is considered to be a ruthless person. Actually, it's not like this at all.

1979, a dermatoglyphic research collaboration group was established in China to conduct a general survey and analysis of dermatoglyphic characteristics of various ethnic groups such as congenital stupidity, schizophrenia and diabetes.

On the other hand, through the observation of complexion and palm color, we can understand personal health status, such as liver palm and even spider nevus of patients with liver disease. Therefore, Chinese medicine hopes, smells, asks and feels, while western medicine hopes, touches, knocks and listens, and observation (looking or seeing) is the first of the four diagnoses. This is only a symptom from the appearance, and scientific diagnosis depends on various physical and chemical detection methods.

Extended data:

Fingerprint is one of the important clues for public security personnel to solve crimes. After the case occurs, it is necessary to obtain the fingerprints left by the criminals when committing the crime, which can be used not only to examine the suspects, but also as evidence of the crime.

It should be pointed out that the understanding of fingerprints abroad was in the middle of19th century. 1892, Argentina solved a murder case with fingerprint identification for the first time, which caused a sensation. All countries in the world have begun to attach importance to fingerprints and regard fingerprint identification as an important evidence for judging a case.

Because everyone's fingerprints are different, in the computer age, scientists invented the fingerprint security lock, and fingerprints became the key. As long as you press your finger on the recognizer, the computer can quickly recognize the fingerprint to determine whether you should open the door. If you have a fingerprint lock at home, you don't need to bring a key as long as you input all the fingerprints of your family into the computer. Everyone can open the door with a touch, which is very safe. Don't worry about losing your keys.
