WebApr 7, 2024 · The spatial distribution of genetic variation reflects evolutionary processes, including drift, migration, and selection, which shape standing variation and the evolutionary potential of populations. WebGenetic drift can also contribute to the evolution of new species by producing genetic divergence across populations. The transfer of individuals or the genes that they carry from one group to another is an example of a mechanism of evolution known as gene flow.
