Natural selection
Key points of evolution by natural selection:
individuals in a species show a wide range of variation
this variation is because of differences in their genes
individuals with characteristics most 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. Given enough time, a species will gradually evolve.
