- Life forms of the past were in some ways very different from living forms of today, but in other ways very similar.
- Most species that once lived on Earth have gone extinct.
- Fossils provide evidence of past life.
- A hallmark of science is exposing ideas to testing.
- Scientists test their ideas using multiple lines of evidence.
- Scientific knowledge is open to question and revision as we come up with new ideas and discover new evidence.
- Scientists use multiple lines of evidence to study life over time.
- Scientists use fossils to learn about past life.
- Scientists use geological evidence to establish the age of fossils.
- There is a fit between the form of a trait and its function, though not always a perfect fit.
- Scientists use multiple research methods (experiments, observations, comparisons, and modeling) to collect evidence.
- Scientists can test ideas about events and processes long past, very distant, and not directly observable.
