How RANDOMNESS Affects My Evolution Simulator - Genetic Drift Explained

Join the LAB! https://www.LearnAdv.com - How does probability relate to evolution? We know that probabilities are not guarantees. When sampling a population, there will be some inherent variation due to randomness alone. However, what determines the strength of randomness?

We call this genetic drift. A more technical definition may be "The effects of random sampling on a finite population size", while others may describe it terms of natural disasters (e.g. A flood wipes out half the population at random). In this video, we dive into the former in our evolution simulator.
