30 minutes Teaching tips:
This article helps dispel the misconception that natural selection is all-powerful and produces perfectly adapted organisms. Classroom discussion (especially regarding the key questions at the beginning of the article) would enhance student learning on these topics. Concepts: - An organism’s features reflect its evolutionary history.
- Anatomical similarities of living things reflect common ancestry.
- Traits that are advantageous often persist in a population.
- There is a fit between the form of a trait and its function, though not always a perfect fit.
