- Present-day species evolved from earlier species; the relatedness of organisms is the result of common ancestry.
- During the course of evolution, only a small percentage of species have survived until today.
- The fossil record provides evidence for evolution.
- There are similarities and differences among fossils and living organisms.
- 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.
