Neutral Theory

A theory in molecular evolution that proposes most genetic variations are the result of genetic drift and not selective forces, and that at the molecular level, the majority of mutations are neutral.

Molecular Evolution

The process of evolution at the scale of DNA, RNA, and proteins, encompassing changes in molecular structure and sequence over time.

Genetic Drift

Random fluctuations in the frequencies of alleles within a population due to chance events.
