What Darwin Didn't Know: The Modern Science of Evolution

Genetic Drift: When Evolution is Random (1x6)

Data di messa in onda: Dic 05, 2018

Explore how population bottlenecks and the founder effect lead to random changes in the frequency of genes, an independent mechanism of evolution known as as genetic drift. Darwin had an inkling of this process when he proposed that “spontaneous variations” play a role in evolution. But genetic drift has proved far more significant than he ever envisioned. For example, it has played a key role in human evolution.
