- Scientific knowledge is open to question and revision as we come up with new ideas and discover new evidence.
- Scientists may explore many different hypotheses to explain their observations.
- 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.
- Evolutionary trees (i.e., phylogenies or cladograms) portray hypotheses about evolutionary relationships.
