Students formulate explanations and models that simulate structural and biochemical data as they investigate the misconception that humans evolved from apes.
National Academy of Sciences
Two class periods.
- Present-day species evolved from earlier species; the relatedness of organisms is the result of common ancestry.
- Similarities among existing organisms (including morphological, developmental, and molecular similarities) reflect common ancestry and provide evidence for evolution.
- A hallmark of science is exposing ideas to testing.
- Scientists may explore many different hypotheses to explain their observations.
- Our understanding of life through time is based upon multiple lines of evidence.
- Scientists use multiple lines of evidence (including morphological, developmental, and molecular evidence) to infer the relatedness of taxa.
