Investigating Common Descent: Formulating Explanations and Models
Author/Source: National Academy of Sciences |
|
| Overview: | Students formulate explanations and models that simulate structural and biochemical data as they investigate the misconception that humans evolved from apes. |
| Concepts: | This lesson covers the following concepts:- Present-day species evolved from earlier species; the relatedness of organisms is the result of common ancestry.
- Similarities among existing organisms provide evidence for evolution.
- Anatomical similarities of living things reflect common ancestry.
- All life forms use the same basic DNA building blocks.
- Scientists pose, test, and revise multiple hypotheses to explain what they observe.
- 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.
- Scientists use anatomical evidence to infer the relatedness of taxa.
