Principles of evolution

1. organisms beget like organisms

2. the number of individuals that survive and reproduce is smaller than the number of individuals in the original population

3. in any given population, there are variations among individual organisms, and some are inheritable

4. Inherited favourable variation become more common from each generation to the next, through natural selection

5. Natural selection leads to the slow accumulation of adaptive changes that differentiate groups, speciation
