Natural Selection: Principles and Examples

Students will investigate how selective pressures act on phenotypes to change allele frequencies in a population, leading to adaptation.

Key Questions

  1. Explain the four main principles of natural selection: variation, inheritance, overproduction, and differential survival/reproduction.
  2. Analyze real-world examples of natural selection, such as antibiotic resistance or industrial melanism in peppered moths.
  3. Differentiate between directional, stabilizing, and disruptive selection patterns and their effects on phenotypic distributions.
