Population evolution is to analyze the specific changes at the genome level that lead to the adaptive evolution of different subgroups based on population genetic differences by performing whole-genome resequencing of representative individuals of different subgroups under different living conditions within a species. The variation of genetic differences among subgroups can also reflect their dynamic changes and mutual influences. The selected genomic regions subject to selection pressure are usually important functional regions, which have important guiding significance for understanding the adaptation of function to the environment.
