IB Biology D4.1.4 Abiotic factors as selection pressures
Practise explaining how environmental changes can shift selection pressures and alter which characteristics are advantageous.
How this is tested
- explain how changed conditions make some characteristics more or less advantageous
- link rainfall, drought or food supply changes to selection in finch beak patterns
- outline why environmental shifts can change survival and reproduction in a population
