- Natural Selection
- Mutation is a in the DNA which results in a new form of gene
- The genes that have produced these successful characteristics are then passed on to the next generation.
- The individuals with the characteristics are most suited to their environment are most likely to survive and breed successfully
- Natural selection works by selecting the organisms best adapted to a particular habitat.
- Classification and Evolution
- studying the simlarities and differences between organisms allow us to classify them into animals plants and microoganisms
- Classification also helps us to understand evolutionary and ecological relationships.
- Accepting Darwin's Ideas
