Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details.
- Features sometimes acquire new functions through natural selection.
- An organism's features reflect its evolutionary history.
- Similarities among existing organisms provide evidence for evolution. (LS4.A)
- Anatomical similarities of living things reflect common ancestry. (LS4.A)
- A hallmark of science is exposing ideas to testing. (P3, P4, P6, P7)
- Scientists test their ideas using multiple lines of evidence. (P6, NOS2)
- 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. (P4, P6, NOS3)
- The real process of science is complex, iterative, and can take many different paths.
- Scientists use multiple research methods (experiments, observational research, comparative research, and modeling) to collect data. (P2, P3, P4, NOS1)
- Science is a human endeavor. (NOS7)
- 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 the similarity of DNA nucleotide sequences to infer the relatedness of taxa. (LS4.A)
- Scientists use anatomical evidence to infer the relatedness of taxa. (LS4.A)
- Scientists may explore many different hypotheses to explain their observations. (P7)
- Not all similar traits are homologous; some are the result of convergent evolution.
- Evolution occurs through multiple mechanisms.
