Regardless of the rate of evolutionary change, the product of genetic alterations is ultimately tested by Natural Selection. Gradualism accounts for the constant yet slow linear modification of a population while punctuated equilibrium accounts for long periods of stasis followed by rapid divergence (multiple forms emerging).
-First, in no more than two sentences, explain Natural Selection (use your own words).
-Second, explain the dynamics of selection. If natural selection acts on individuals, how might it
shift allele frequencies in a population?
-Third, explain gradualism and punctuated equilibrium in terms of selection. When discussing
punctuated equilibrium, remember that selection is still active in times of stasis
