Evolutionary Mechanisms

Virginia SOL BIOII.5

Investigate how evolutionary mechanisms affect the genetic makeup of populations over time.

Study BIOII.5 with SOL PrepBack to Biology II Advanced Survey

What students need to be able to do

  • Make, support, and evaluate a claim about the effect of selective pressures on species evolution.
  • Explain the effect of changing environmental conditions on the allele frequencies in a population.
  • Develop and use a model to explain how evolutionary factors (gene flow, genetic drift, mutation, non-random mating, and natural selection) change allele frequencies over time.
  • Develop and use a model to explain the effects of inbreeding and genetic drift in small, isolated populations.
  • Make, support, and evaluate a claim about how speciation occurs.
  • Make, support, and evaluate a claim about how evolution happens at the population level.
