Use this resource to relate evolutionary concepts to the topics of biogeochemical cycles, global climate change, and ecosystems (or get more suggestions for incorporating evolution throughout your biology syllabus). This article includes a set of discussion and extension questions for use in class, as well as advanced discussion questions for undergraduates. 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.
- Evolutionary change can sometimes happen rapidly.
- Artificial selection provides a model for natural selection.
- Evolution results from natural 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.
- Natural selection may favor individuals with one extreme value for a trait, shifting the average value of that trait in one direction over the course of many generations.
- 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.
- Scientists use experimental evidence to study evolutionary processes.
- Scientists use artificial selection as a model to learn about natural selection.
