- Present-day species evolved from earlier species; the relatedness of organisms is the result of common ancestry.
- An organismís features reflect its evolutionary history.
- The fossil record documents the biodiversity of the past.
- The fossil record documents patterns of extinction and the appearance of new forms.
- All life forms use the same basic DNA building blocks.
- Scientists can test ideas about events and processes long past, very distant, and not directly observable.
- Our knowledge of the evolution of living things is always being refined as we gather more evidence.
- Scientists use the similarity of DNA nucleotide sequences to infer the relatedness of taxa.
- Scientists use fossils (including sequences of fossils showing gradual change over time) to learn about past life.
