This data-driven activity accompanies the video Selection for Tuskless Elephants. It engages students in analyzing data to make evidence-based claims about the occurrence of 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.
In this hands-on activity, students analyze the results of genetic crosses between stickleback fish with different traits. It complements the film Evolving Switches, Evolving Bodies.
