Quizplus · Accepted Answer

Variability and competition are essential for evolution by natural selection. Variability refers to the genetic diversity within a population that provides the raw material for natural selection to act upon. Competition for resources, including food, water, and mates, leads to differential survival and reproduction of individuals with advantageous traits, which then become more common in the population over time. Individualism, diffusion, progress, mutation, and instinct are not essential for evolution by natural selection.
