- Biological evolution accounts for diversity over long periods of time.
- There is a fit between organisms and their environments, though not always a perfect fit.
- Similarities among existing organisms (including morphological, developmental, and molecular similarities) reflect common ancestry and provide evidence for evolution.
- Evolution occurs through multiple mechanisms.
- Natural selection and genetic drift act on the variation that exists in a population.
- New heritable traits can result from mutations.
- Natural selection can act on the variation in a population in different ways.
- Natural selection is capable of acting at multiple hierarchical levels: on genes, on cells, on individuals, on populations, on species, and on larger clades.
- 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.
