This activity builds on information presented in the video Selection for Tuskless Elephants. Students use scientific evidence and reasoning to construct an explanation of and develop an argument for tusklessness in elephant populations.

In this activity, students collect and analyze evidence for each of the major conditions for evolution by natural selection to develop an explanation for how populations change over time.

This lesson supports concepts covered in the film The Birth and Death of Genes. After watching the film and reading a couple of scientific passages, students explain how understanding about icefish adaptations might help develop treatments for health conditions.
