Evo in the News: Climate change causes loss of genetic diversity
To rate this resource, click a star:
This news brief, from April 2012, describes how climate change is affecting a population of chipmunks in Yosemite National Park. The chipmunks' loss of genetic variation may affect their ability to survive and their future evolutionary potential.

- Evolution results from selection acting upon genetic variation within a population. (LS4.B)
- The amount of genetic variation within a population may affect the likelihood of survival of the population; the less the available diversity, the less likely the population will be able to survive environmental change.
- Natural selection acts on the variation that exists in a population. (LS4.B, LS4.C)
- As with other scientific disciplines, evolutionary biology has applications that factor into everyday life.
- There is variation within a population. (LS3.B)
