This article encourages students to reason about scientific data. It includes a set of discussion and extension questions for use in class, as well as a video podcast. It also includes hints about related lessons that might be used in conjunction with this one. Get more tips for using Evo in the News articles in your classroom.
Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details.
- Evolution results from natural selection acting upon genetic variation within a population.
- Evolution results from mutations.
- New heritable traits can result from mutations.
- Mutation is a random process.
- Inherited characteristics affect the likelihood of an organism's survival and reproduction.
- 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.
- Traits that confer an advantage may persist in the population and are called adaptations.
- 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.
