Simulation:
A common ancestor population of ostrilopes was split into two different environments:
- Environment A
- Environment B.
Model one of these environments in the Natural Selection Simulation, and you will both compare the descendant species that come from these two populations. First, predict whether each ostrilope population will change, and if so, how it will change.

Predict the population in Environment A, which changed to have some tall Thornpalms (trees).
Do you think the population in Environment A will remain stable or change over time if thornpalms are taller?
