IB ESS 3.1.4 Natural selection
Practise outlining natural selection as a mechanism for evolution, using selection pressures and inherited variation in real species contexts.
How this is tested
- outline natural selection using variation, mutation, selection pressure and inheritance
- apply natural selection to contexts involving inherited variation and selection pressure
- link survival of better-adapted individuals to biodiversity over long timescales
