Evolution ...
- is the change in a population over many generations
- may result in the formation of a new species whcih is better adapted to it's environment.
1. Individual organisms within a species show variation because of differences in their genes.
2. Individuals better adapted to their environment are more likely to survive , breed successfully and produce offspring. This is survival of the fittest.
3. The survivors pass on their genes to their offspring, reulting in an 'improved' organisation evolving through natural selection.
Gene mutations may bring about a more rapid change in a species.
