I can explain what is meant by selective breeding and why it is important for human food security.
Lesson details
Key learning points
- Some plants and animals have features that are useful to us (e.g. they can provide food and materials, or do work).
- Selective breeding by humans causes particular features to become more (or less) common in the species.
- After many generations, the resulting domesticated species can be quite different to their wild ancestors.
- Examples of the selective breeding of a farm animal and a crop from their wild ancestors.
- The dependence of humans on domesticated animals and crops for food security.
Common misconception
