Product Description
Have students create a genetic drift story!
This half-sheet prompt contains instructions for writing a fun story relating to the creatures of Arthropod Islands. Students are instructed a story which includes both types of genetic drift (founder effect and bottleneck effect). It allows them to write this story as either a handwritten story, typed up story, or a comic book. This differentiation in the delivery helps students get excited about this story.

In fact, there's a wide variety in how the students can go about creating this story. They are allowed to pick their own arthropod species and they can pick their own bottleneck event.

Tip: In order to grade these easier, have students "swap", read each other's stories, and have them highlight certain, required aspects. This way, you only have to read the highlighted/marked portions.

Here is what I ask the students to do with each other's stories:
- Underline the specific species of arthropod
- Circle the two phenotypes specified
- Draw an arrow to the paragraph that mentions how the mainland's different (ie, explains the founder effect)
- Highlight the bottleneck event
- Star the paragraph where it explains how the phenotypes were different after the bottleneck effect

This worksheet is created to be printed and cut in half, to reduce paper usage.
