Discover 3 specific genes that help us evolve into humans!

It is not an easy task to find human evolutionary genes out of 3 billion base pairs. A team of researchers recently discovered three genes created by non-coding DNA, which may have helped humans evolve into high-level animals like today.

Genetically, humans and chimpanzees are very similar, but we can easily distinguish there are many differences between humans and chimpanzees. According to the genome research journal, scientists have recently discovered a very important gene, these genes and primates have a close relationship, which will bring A new ability explains why we become the only human species.

The general perspective on the field of molecular evolution suggests that genes are only formed from genes that were created from the previous generation through copying or reorganizing. Most genes are from ancient times and have a long history, being able to find out about the ancestral period of humanity while still living on trees, even those that existed for a long time. From the thousands of genes of microorganisms increased to tens of thousands of genes in humans, this process is mainly done through gene organization or copying, the copying process creates another genome, then self by developing new functions and DNA sequences.

Most of the copying process takes place before humanity is born, only a few occur in generations of humans. From a positive gene produces a protein-coding gene that is thought to be an impossible thing. However, the latest research results show that this phenomenon really exists.

The researchers found that, in the body of fruit flies, yeast and primates, there exists a gene created by non-coding DNA, but so far, there have been no findings about these genes. in humans. This research raises a problem that makes people curious, how do these genes make a difference between us and primates ?

David Gonzalez Knowles and Aoife McLysaght - two Trinity College Dublin researchers (TCD), Ireland have acknowledged that this is an extremely difficult task to find genes that encode proteins in black chimpanzees as in the human genome. They have adopted careful screening methods and excluded some false results, the end result has only 3 left over. But they must face a challenge to prove these genes in human DNA with active activity.

The researchers collected these three genes from other research results, able to record and decode into evidence of protein, and they must also prove that the corresponding DNA sequence does not work on animal species. Primate. They found that the DNA sequence of some gibbons and monkeys carries a difference that makes the protein-coding gene disappear. This proves that these genes do not work on primates.

The researchers also noticed, due to the strict screening process, only about 20% of human genes could be analyzed. So they envisage in the process of human evolution, non-coding DNA produces about 18 genes. Compared to a total of 24,000 genes, this number seems too little, but it is extremely important.

The discovery of new genes encoding proteins is an important finding, but offers a more important problem; What effect does the protein produced by these coding genes produce? It is completely different from other human genes, can even bring about a great influence. Although the characteristics and functions of these genes have not been answered yet, researchers have boldly speculated, because thanks to these special genes have created human characteristics.
