IB Biology A4.1.1 Evolution as change in heritable characteristics
Practise defining evolution as heritable change and explaining how variation, mutation and selection alter characteristics over time.
How this is tested
- identify evolution as change in heritable characteristics of a species
- explain how mutation and sexual reproduction generate variation for selection
- apply natural selection to changes in allele frequencies over generations
