Question: How does a population change over time? 1. Experiment: Set the Background color to the values shown in the last column of the table
below. Record the Average fitness of generation 1 in the second column of the table. Click
on the insects and find the individual with the greatest fitness. (In the first generation, all the
insects will have the same fitness). Record that individual's phenotype in the table's third
column.
Move the Sim. speed slider a quarter of the way to the right. Run the Gizmo, and complete
the table for each listed generation. (The generation number does not have to be exact.)
