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.

Question 1
1.

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.

Question 2
2.

Are all traits that are introduced by mutations adaptive? Do you think non-adaptive traits can be introduced into a population through mutations? Why or why not?
CFS:
  • accurately identifies the traits in the environment
  • accurately describes the adaptive or non-adaptive nature of the traits in the environment
"I think that all traits introduced into the environment (are / are not) adaptive because ..."

  • 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.
