After a child is born, choosing a name is a top priority, which entrusts parents or elders in the family with good expectations for the child's future. When the children are older and the fingerprints are clear, many family members of the older generation begin to pay attention to the shape of the children's fingerprints, and many people have experienced such a scene, including the post-90s generation like me.
I still remember that my mother and grandmother looked satisfied after seeing the fingerprints of my hands, and I already had a certain memory ability at that time, and after their repeated confirmation, I determined: 9 of the 10 fingers on my hands are snails!
As the saying goes, "Nine buckets and ten buckets are more and more there", "Nine Luo nine, do too shou, ten Luo Quan, the champion", "Nine Luo and a dustpan, eat dry at once", the "bucket" and "Luo" in the saying are actually the meaning of "snails". Although they don't have much education, they also know that such folk rumors are not very credible, but they still feel that this is a "good sign".
Of course, as more and more people receive higher education, whether the child's fingerprint is a snail or a dustpan is just a matter of watching and playing, because the wealth of a person's life is not only given by the family at birth, but then he has to rely on himself to fight for it, and he will not lie flat because the fingerprint has 9 or 10 snails.
However, when the team of Fudan and the Chinese Academy of Sciences recently studied fingerprints, they uncovered some genetic mysteries that can be found through fingerprints, mainly involving three major aspects, which can be said to be related to each of us. The relevant research results have been published in Cell, which may not be heard of by most people, but this is an international authoritative academic journal, in the whole research process, not only Fudan University and academicians of the Chinese Academy of Sciences such a strong research team, but also with more than 10 foreign scientific research institutions, let's see what major discoveries there are!
"Bucket" and "dustpan" have nothing to do with skin development, the fingerprint pattern is formed as early as the embryonic development, and its type does not change after birth!
According to the researchers, Asians as a whole have a situation of "less kei and more buckets", and some people may even have a "bow type". This time the researchers' research on fingerprint patterns can be said to be the largest so far, through genome association analysis, it was found that 43 human genetic loci are associated with the patterns of fingerprints on our hands, but none of them show that they are related to skin development, even if our fingerprints are grown on the skin, they are actually closely related to the development of limbs.
To be more specific, the length ratio of a person's fingers is related to the fingerprint pattern, if a person's little finger is longer, then his palm length will be relatively shorter, and most of the ten fingers of the two hands are bucket patterns. If the knuckle distal to your index finger looks longer, it's usually more of a dustpan.
Is there a correlation between the stria phenotype and congenital genetic diseases, "palmistry is a disease" or does it come true?
According to the researchers, the scientific community has discovered a basic fact before this, that is, many congenital genetic diseases have been shown to be related to the dermatoglypin phenotype, specifically for example: patients with Down syndrome may have body dermatoglyphic phenotypes such as the arch of the toe and the severed palm.
Many people may not know that as early as the 60s of the 20th century, there were studies that found that many leukemia patients were people with more bucket-shaped fingerprint patterns, but no one knew why this happened.
The results of this research have laid a theoretical foundation for the association between diseases and fingerprint patterns, and the researchers said that it is also possible to achieve "palmistry diseases" in the future. In addition, the research team has obtained an invention patent, which is the "Down syndrome skin pattern assisted screening", which is the first new system to assist in the screening of Down syndrome from the skin pattern phenotype.
In the world's first "human phenome navigation map", a team of Chinese scientists has found more than 1.5 million strong associations, and most of them are discovered for the first time, and 39% of them have crossed the field!
No one is unaware of how powerful the genes are, just as when the same virus infects different subjects, some people will die because of it, but there are also people who have no obvious symptoms. Scientists study how there is a relationship between fingerprint patterns and an individual's limb phenotype, which is actually to study how the internal code of genes communicates with genes in a specific environment, and then what phenotypic characteristics are expressed externally.
There are hundreds of millions of people on the planet, but every person in the world, including those who have lost their lives and those who are still alive, has always had a unique fingerprint, but until now, we have not understood all the reasons behind this phenomenon. Researchers will further expand the group of participants and uncover some of the phenotypic traits that may not have been discovered by scientists yet, but are relevant to the human condition!
