Biologists have discovered that female cheetahs consistently seek out multiple mates. This news brief, from July 2007, explains how the evolutionary implications of this behavior may help conservation efforts targeting these endangered animals.

- Evolution results from selection acting upon genetic variation within a population. (LS4.B)
- Traits that confer an advantage may persist in the population and are called adaptations. (LS4.B, LS4.C)
- Inherited characteristics affect the likelihood of an organism's survival and reproduction. (LS4.B, LS4.C)
- 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.
- Scientists test their ideas using multiple lines of evidence. (P6, NOS2)
- Scientific knowledge is open to question and revision as we come up with new ideas and discover new evidence. (P4, P6, NOS3)
- Our knowledge of the evolution of living things is always being refined as we gather more evidence.
- As with other scientific disciplines, evolutionary biology has applications that factor into everyday life.
- There is variation within a population. (LS3.B)
