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 formulate a hypothesis and collect and analyze real research data about how quickly natural selection can act on specific traits in a population as a result of predation. It is accompanied by a short video that describes the experiment this activity is based on.
This activity reinforces concepts of variation and natural selection covered in the short film Natural Selection and Adaptation. Students apply the Hardy-Weinberg equation to real data collected on rock pocket mouse populations.
This interactive, modular lab explores how stickleback fish and fossil specimens are used to study evolutionary processes, with an emphasis on data collection and analysis.
