Explore stickleback evolution using a computer model
Use the stickleback evolution model to explore the impact of mutation and predation on the changes in stickleback lateral plate morphs (LPM) over time. Open an online data sheet (you will be asked to make a copy of the datasheet).
Set up the model. Keep everything as default. Ensure that
Eda-allele-ratio-A:a = 1,
mutation as unchecked, and
Predator type = no predator
Record the Complete-plated (%), Low-plated (%), and Total # of fish in year 0
Run the model for 30 years. To speed up, drag the model speed bar toward the right.
Record the Complete-plated (%), Low-plated (%), and Total # of fish in year 30
Repeat steps 1-4 with Predator type = predatory fish and then predatory insects.
Repeat steps 1-5 with mutation checked
