Explain natural selection as the mechanism of evolution: heritable variation + competition for resources + differential survival and reproduction = change in allele frequency over generations

If your child heard about bacteria becoming resistant to antibiotics, could they explain how that happened using natural selection — without the bacteria ‘choosing’ to change?

Builds on
Genetic Mutationages 12–14Mutation is the ultimate source of heritable variation — understanding this grounds the mechanism of natural selection
Variation in Speciesages 12–13Natural selection requires heritable variation to act on — understanding the nature of variation is a prerequisite
Classifying Organismsages 10–11Natural selection explains the diversity of life that classification systems attempt to organise — KS2 broad classification provides context
Dinosaur-to-Bird Transitionages 11–13Advanced biomechanical analysis depends on understanding what fossil evidence can and cannot preserve
The Red Queen Hypothesisages 11–12KS3 natural selection provides the mechanism that drives both sides of an evolutionary arms race
Sexual Selectionages 12–13KS3 natural selection underpins kin selection, sexual selection, and behavioural game theory as extensions of the same mechanism

Unlocks
Extinction & Rapid Changeages 12–14Extinction is what happens when natural selection cannot produce adaptations fast enough — the mechanism must be understood first
Evidence for Evolutionages 12–14Evidence for evolution supports the theory of evolution by natural selection — the mechanism to be evidenced should be understood first
