Overview: The evolutionary biologist Jim Bull gives his perspective on how evolution matters to society today: from producing polio vaccines to solving tabloid-style crimes. This article appears at ActionBioscience.org. Author/Source: ActionBioscience.org Grade level: 9-12 Time: 20 minutes Teaching tips: This article is rather technical, but it is also a good introduction to some interesting applications of evolutionary theory. This might be a good resource for AP biology students, who already have a basic understanding of the mechanisms of evolution. Concepts: Scientists test their ideas using multiple lines of evidence. Scientific knowledge is open to question and revision as we come up with new ideas and discover new evidence. Scientists use multiple research methods (experiments, observational research, comparative research, and modeling) to collect data. As with other scientific disciplines, evolutionary biology has applications that factor into everyday life. Teacher background: Relevance
