How Random Luck Shapes Evolution: Understanding Genetic Drift

Miacademy & MiaPrep Learning Channel

This educational video provides a clear and engaging exploration of genetic drift, a mechanism of evolution driven by random chance rather than adaptation. Through dynamic examples and clear visual aids, the host explains how random events—like storms, fires, or migration—can dramatically alter the genetic makeup of a population. The video contrasts genetic drift with natural selection, emphasizing that survivors of these events are often just "lucky" rather than better adapted.
