• The Hardy-Weinberg equation to determine the predicted frequency of genotypes
• Natural selection - differential survival of groups of organisms
• Effects of genetic drift
• Effects of reproductive or geographic isolation
• Analyzing fossil evidence
• Comparative embryology
• Branching diagram (cladogram) that shows probable evolutionary relationships
• Estimating how long ago various groups of organisms diverged evolutionarily from each other
