| Research finds evidence of genetic evolution in European populations changed by natural selection in the past 3000 years |
Chinanews.
com, Beijing, November 16 (Reporter Sun Zifa) Springer Nature's professional academic journal "Nature-Human Behavior" recently published a genetics research paper, for the past 2000-3000 years, natural selection in the European population The role of genetic evolution provides insights and evidence
.
The study completed by Chinese scholars identified the genetic effects associated with 755 traits altered by natural selection over the past 3000 years, indicating that this process continues to have an impact on the human genome
The paper claims that natural selection is one of the ways in which evolution takes place, which can lead to small changes between generations
.
Past discoveries have revealed how natural selection has shaped the evolution of the human species, but little is known about the subsequent effects of selection
The author of the paper, Song Weichen, Shanghai Jiaotong University School of Medicine, and colleagues used modern human genetic data from the British Biobank and the Mental Disease Genome Society, as well as ancient human genome DNA from all over Europe, in the time span from the rise of Homo sapiens as a species to today , To investigate the evidence of natural selection among European populations
.
According to their research, the genetic effects of 755 complex traits (associated with multiple genetic effects and environmental factors) in European populations have been changed by natural selection in the past 3000 years
.
This includes traits associated with a variety of genetic effects, including pigmentation, nutrient intake, and a variety of common diseases and disorders, such as inflammatory bowel disease and anorexia nervosa
The author of the paper concluded that although these results cannot determine whether these genetic effects have a causal effect on complex traits, and only European data are used, so the universality is limited, these results can be used as a basis for future studies on human genetics and evolution.
