Neutral Evolution - Genetic Drift and Molecular Clocks

Explore the concept of neutral evolution and genetic drift in this 44-minute lecture from Yale University's "Principles of Evolution, Ecology and Behavior" course. Delve into how genes can evolve without the influence of natural selection, occurring when mutations don't affect reproductive success. Examine the role of neutral mutations in genotypes and phenotypes, and how this "genetic drift" can serve as a molecular clock for determining common ancestors. Learn about the mechanisms of neutral evolution, its significance in the history of life, and how it contributes to our understanding of phylogenetic relationships. Gain insights into the complexities of evolutionary biology through detailed explanations and examples provided in this comprehensive academic lecture.
