Q
What are the 6 key points of evolution by natural selection?
A
- Individuals in a species show a wide range of variation
- Inherited variation is due to differences in their genes
- Individuals with the features that are best suited to the environment are more likely to survive and reproduce
- The genes that allow these individuals to be successful are passed to their offspring
- Individuals that are poorly adapted to their environment are less likely to survive and reproduce. This means that their genes are less likely to be passed to the next generation
- Over many generations these small differences add up to the new evolution of species
