Danish scientists have shown that human mutations are slower than other apes January 28, 2019 Source: Science and Technology Daily Author: Liu Xia In the past one million years, the rate of human genetic mutation has slowed down. Image source: US Newsweek website According to a recent report by the US Newsweek website, Danish scientists have sequenced the genes of the chimpanzee, gorilla and orangutan families, and compared the results with similar studies on humans, and reached a new conclusion: the human gene mutation rate is obvious Slower than our closest relatives - other apes. The first author of the research paper, Soren Bessenbach of Aarhus University, said: "In the past six years, several large studies have done a lot of research on humans, so we have the number of new genetic mutations in humans every year. But so far, we have not conducted in-depth research on the genetic mutation rate of human primates." This time, researchers studied the aphid family and compared the genetic differences between their different generations to clarify the number of genetic mutations that occur each year. Overall, new research shows that the annual mutation rate of humans is about one-third lower than that of other humans. The researchers say that these results are important for understanding when humans and other apes are evolving in the process of "divoring". Using the mutation rate calculated in the study, the team proposed a new time point for the separation of humans and humans. They estimate that the evolutionary separation of humans and chimpanzees was about 6.6 million years ago; humans were separated from orangutans about 15.9 million years ago. Previous estimates suggest that humans are separated from chimpanzees, gorillas, and orangutans by about 15 million, 19 million, and 35 million years ago, but these estimates do not match fossil records. In addition, the researchers believe that the latest paper is also expected to have an impact on the protection of orangutans. Christina Wissom of the Copenhagen Zoo said: "All kinds of apes are in the wild. People can more accurately trace the response of different races to climate change. We can also understand how species respond to the future. climate change." YT-H711 YT-H711 Shenzhen Sunshine Technology Co.,Ltd , https://www.szyatwin.com
