Investigating Mutant Fur Traits in the Sim
In the Sim activity that follows, you will investigate a low-fur population of ostrilopes with the trait distribution shown in the histogram below.
- In the Sim, you will be able to turn on mutations for fur traits.
- You will make the environment for this population cold.
- Before you do this, study the histogram below and answer the questions that follow.
Think about which new traits would be adaptive and non-adaptive in a cold environment. Label any traits that would be adaptive with an A. Label any traits that would be non-adaptive with an NA.

- Open the Natural Selection Simulation and open the mode: Mutations and Traits.
- Change the temperature of the environment to cold (Level 1) by moving the Temperature slider.
- Turn ostrilope fur-trait mutations on by pressing the Ostrilope icon and pressing the Mutations toggle.
- Press RUN and observe the population for at least 50 generations.
- Press ANALYZE and use the Generations slider to carefully observe new traits in the population.
