Natural Selection

Natural Selection Simulation Part 2

1. Place 10 pictures of Rabbit A and 10 pictures of Rabbit B in an area about the size of two sheets of paper.

2. Drop one picture of Fox B on the rabbits. If it lands on one or more pictures of Rabbit A, remove the rabbits from the population. Repeat this TWO times. Fox B is slower that Fox A, so he only gets two chances. Since Rabbit B runs faster, assume none of them will be captured even if the fox lands on them.

3. Add a new fox to the fox population for every rabbit eaten after the TWO attempts at catching rabbits.

4. Complete the table below for the first generation.

5. Double the number of rabbits left for the start of the second generation.

6. Continue doing this until all of the A rabbits are consumed.
