  • Standard 7.d: Students know variation within a species increases the likelihood that at least some members of a species will survive under changed environmental conditions.

Students should be able to:

  • Predict how differing genetic traits will increase probability of survival in a given environment.

  • Develop a hypothesis explaining how alterations to the environment gave dark forms of peppered moths advantages over pale forms during the Industrial Revolution.
