- Present-day species evolved from earlier species; the relatedness of organisms is the result of common ancestry. (LS4.A)
- The patterns of life's diversity through time provide evidence of evolution.
- Features sometimes acquire new functions through natural selection.
- An organism's features reflect its evolutionary history.
- The fossil record provides evidence for evolution.
- The fossil record documents the biodiversity of the past.
- The fossil record contains organisms with transitional features.
- There are similarities and differences among fossils and living organisms.
