Study says external gene invasion affects brain formation in mammals

a joint team of researchers from the Tokyo Institute of Technology and the Institute of Science and Chemistry in Japan found that a particular genetic information that accidentally entered vertebrate genes about 400 million years ago played an important role in later brain development in mammalsThis is the first evidence that genetic genes may have entered vertebrates due to external information and have played a decisive role in the evolution of mammals, which is important for uncovering the birth and evolution of mammalsThe findings appear in the recently published Proceedings of the American Academy of SciencesThe joint team investigated the genetic genes of various animals and followed the short-arranged genetic information of the reverse transcription transsonatiats that entered the vertebrate genetics at some stage in the evolutionary process and kept them in the genetic genes of their offspring, and found that specific reverse transcription transscoels were common in reptiles, birds and mammals, but only in mammalsThe brain tissue of this particular reverse transcription translucent is reflected in the distinctive sensory parts of mammals such as the mouse's beard and the tip of the mole's nose, which reptiles and birds do not haveThe team found that as reverse transcription transners enter the genetic system, stimulate the genetic field and stimulate genetic activity that determines the location of brain tissueThe team concluded, using fossils and other reasons, that reverse transcription transgenes entered the genetic system of vertebrates about 400 million years ago, and that the common ancestor of mammals acquired a highly developed brain function about 200 million years agoProfessor Hiroshi Okada, of the Tokyo Institute of Technology's Life Science and Engineering, believes that in genetic research, there are more research results on small evolutions such as sudden mutations, but the results of large evolutionary studies that have brought about great changes in the structure of the body from the outside have brought about great changes in the structure of the body(Chen Chao)
