This article is most appropriate at the AP level. It includes a set of discussion and extension questions for use in class and hints about related lessons that might be used in conjunction with this one. This example could easily be integrated into instruction on mutation and recombination. Get more tips for using Evo in the News articles in your classroom.
- An organismís features reflect its evolutionary history.
- Evolution results from selection acting upon genetic variation within a population.
- Over time, the proportion of individuals with advantageous characteristics may increase (and the proportion with disadvantageous characteristics may decrease) due to their likelihood of surviving and reproducing.
- Scientists can test ideas about events and processes long past, very distant, and not directly observable.
- Our knowledge of the evolution of living things is always being refined as we gather more evidence.
