This activity explores images of elephants with and without tusks, which serve as phenomena for learning about selection and human impacts on the frequency of traits within populations.
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.
This video follows Joyce Poole and other scientists working in Gorongosa National Park, Mozambique, who made the observation that many female elephants lack tusks.
