This lesson is driven by the question: Why is a new flu vaccine needed every few years? Students answer this question and gather other information about evolution and influenza as they create an outline of a brochure for a biotechnology company.

The exercise does a good job addressing the process of genetic sequence change, but it’s short on making the role of natural selection clear. Supplement with additional discussion or a short video on natural selection.
Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details.
- Evolution is still continuing today.
- Evolution results from natural selection acting upon genetic variation within a population.
- Traits that confer an advantage may persist in the population and are called adaptations.
- Natural selection can act on the variation in a population in different ways.
- As with other scientific disciplines, evolutionary biology has applications that factor into everyday life, for example in agriculture, biodiversity and conservation biology, and medicine and health.
