Summary
Natural selection significantly impacts human genome variation. Recent research increasingly focuses on how selection affects functionally important genetic variants, moving beyond those with unknown effects.
Area of Science:
- Human genetics
- Evolutionary biology
- Population genetics
Background:
- Natural selection is a key driver of human genome variation.
- Previous studies predominantly examined genetic variants lacking clear phenotypic associations.
- A shift towards investigating functionally significant variants is occurring.
Purpose of the Study:
- To highlight the evolving trend in genetic studies of natural selection.
- To emphasize the increasing focus on functionally important genetic variants.
Main Methods:
- Review of recent genetic studies on natural selection.
- Analysis of trends in variant selection based on phenotypic association.
Main Results:
- Most prior research concentrated on genetic variants with unknown phenotypic effects.
- Current studies are increasingly identifying the impact of natural selection on variants with known or probable functional significance.
Conclusions:
- The field is advancing to understand natural selection's role in functionally relevant human genetic variation.
- Future research will likely build upon the growing body of evidence linking selection to important functional genetic variants.
