This article is fairly advanced but would make a good reading to stimulate further discussion of the nature of science. Concepts: - The fossil record documents the biodiversity of the past.
- A hallmark of science is exposing ideas to testing.
- Scientists test their ideas using multiple lines of evidence.
- Scientists can test ideas about events and processes long past, very distant, and not directly observable.
- Scientific knowledge is open to question and revision as we come up with new ideas and discover new evidence.
- Scientists use multiple research methods (experiments, observational research, comparative research, and modeling) to collect data.
- Science is a human endeavor.
- Our knowledge of the evolution of living things is always being refined as we gather more evidence.
- Our understanding of life through time is based upon multiple lines of evidence.
- Scientists use fossils (including sequences of fossils showing gradual change over time) to learn about past life.
- Scientists use the geographic distribution of fossils and living things to learn about the history of life.
- Scientists may explore many different hypotheses to explain their observations.
