Overview
This news brief, from September of 2008, describes an unusual contagious cancer currently decimating Tasmanian devil populations. Learn about the fascinating interplay between the evolution of the devils and the evolution of the disease.
- [History of life: Grades 9-12] Geological change and biological evolution are linked.
- [History of life: Grades 13-16] Geological change and biological evolution are linked.
- [Mechanisms of evolution: Grades 9-12] Evolution results from selection acting upon genetic variation within a population. (LS4.B)
- [Mechanisms of evolution: Grades 9-12] The amount of genetic variation in a population may affect the chances of survival of the population; the less diversity, the less likely the population will be able to survive environmental change.
- [Mechanisms of evolution: Grades 9-12] Traits that confer an advantage may persist in the population and are called adaptations. (LS4.B, LS4.C)
- [Mechanisms of evolution: Grades 9-12] Over time, the proportion of individuals with advantageous characteristics may increase due to their likelihood of surviving and reproducing. (LS4.B, LS4.C)
- [Mechanisms of evolution: Grades 13-16] Evolution results from natural selection acting upon genetic variation within a population.
- [Mechanisms of evolution: Grades 13-16] Natural selection and genetic drift act on the variation that exists in a population.
- [Mechanisms of evolution: Grades 13-16] Variation of a character within a population may be discrete or continuous.
- [Mechanisms of evolution: Grades 13-16] Over time, the proportion of individuals with advantageous traits may increase (and the proportion with disadvantageous traits may decrease) due to their chances of surviving and reproducing.
- [Mechanisms of evolution: Grades 13-16] Traits that confer an advantage may persist in the population and are called adaptations.
- [Nature of science: Grades 9-12] Scientists can test ideas about events and processes long past, very distant, and not directly observable.
