5.2 - Natural selection
Assessment statements
| DCS Topic Code | Statement | Guidance |
| 5.2.U1 | Natural selection can only occur if there is variation among members of the same species. | |
| 5.2.U2 | Mutation, meiosis and sexual reproduction cause variation between individuals in a species. | |
| 5.2.U3 | Adaptations are characteristics that make an individual suited to its environment and way of life. | |
| 5.2.U4 | Species tend to produce more offspring than the environment can support. | |
| 5.2.U5 | Individuals that are better adapted tend to survive and produce more offspring while the less well adapted tend to die or produce fewer offspring. | |
| 5.2.U6 | Individuals that reproduce pass on characteristics to their offspring. | Students should be clear that characteristics acquired during the lifetime of an individual are not heritable. The term Lamarckism is not required. |
| 5.2.U7 | Natural selection increases the frequency of characteristics that make individuals better adapted and decreases the frequency of other characteristics leading to changes within the species. | |
| 5.2.A1 | Changes in beaks of finches on Daphne Major. | |
| 5.2.A2 | Evolution of antibiotic resistance in bacteria. |
