- Evolution results from natural selection acting upon genetic variation within a population.
- Inherited characteristics affect the likelihood of an organismís survival and reproduction.
- Over time, the proportion of individuals with advantageous characteristics may increase (and the proportion with disadvantageous characteristics may decrease) due to their likelihood of surviving and reproducing.
- Scientific knowledge is open to question and revision as we come up with new ideas and discover new evidence.
- As with other scientific disciplines, evolutionary biology has applications that factor into everyday life, for example in agriculture, biodiversity and conservation biology, and medicine and health.
