Explain why there are more white bunnies than brown in this environment.ĩ. This time, click the corner button to change the environment to “snowflake.” Add wolves. Add wolves as an environmental factor and a brown fur mutation. Suggest a reason for why limiting food (instead of wolves) changes the outcome.Ĩ. Describe what happens over 12 generations to the number of bunnies with brown and white fur with limite food as a selection factor. This time, instead of wolves, limit the food as an environmental factor. Let the bunnies populate for 2 generations. Click the button for a dominant brown fur mutation. Suggest a reason for why there are more bunnies with brown fur.ħ. (Don’t forget to add a mate)ĭescribe what happens over 12 generations to the number of bunnies with brown and white fur. Let the bunnies populate for 2 generations then click to Wolves as an environmental factor. Click the button for dominant brown fur mutation. Suggest a reason for why there are more bunnies with short teeth than long teeth when food is limited.Ħ. Click off the “total” to more clearly see the factors and zoom out.ĭescribe what happens over 12 generations to the number of bunnies with short and long teeth. Note that the graph now has three lines, one for short and one for long teeth, and one for total. Note this will add a mutation for bunnies to have longer teeth.Ĭlick on “limited food” for an environmental factor. Reset the simulation and click on the button for dominant long teeth. Animals have adaptations that can help them survive in their environment. Sketch the graph shown of the bunnies for 6-10 generations. Click “zoom out” on the graph to see the bunny numbers.ĭescribe what happens to the bunnies when food is limited. Start your simulation over and click “limited food.” and then “add a mate.” Run the simulation for 12 generations. In nature, populations don’t get out of control because there are limiting factors in the environment.
What happens when you click on the snowflake?Ĥ. In the top right corner of the screen is a sun and a snowflake. ***Click on the RESET button and you will get another bunny and the screen will return to its original.ģ.
There are three environmental factors listed that can also be changed. What mutations can you add to your bunny?Ģ.
Look for the area that says “add mutations.” The simulation allows you to control types of mutations that occur in the bunnies. When you first open the simulation, one bunny will be shown on your screen.
