The Gene B. Genetic Drift Theory

Genetic drift is a natural process in evolution where random changes in a population's gene pool occur over generations. Unlike natural selection, which favors traits that improve survival and reproduction, genetic drift can lead to certain traits becoming more or less common purely by chance. This is especially significant in small populations, where random events can dramatically shift gene frequencies. Over time, genetic drift can lead to a loss of genetic diversity, potentially affecting a population's ability to adapt to environmental changes.
