With the same parameter values as before, re-start the simulation (i.e. press setup, then press go again). You will notice that when better technology levels appear they tend to be clustered in certain regions. Why is this?
a. Because squares nearby the innovator forget what they are doing.
b. Because when a square innovates, the neighboring squares can copy it. This cause the innovation to spread forming a patch of squares to have the same color.
c. Because when a square innovates its fitness increases and it has children that inherit their technology.
d. Because nearby patches tend to be smart and so they innovate in groups.
