Testing the Hypotheses:
Simulation One
In the first simulation, you've stocked your pool with about one
hundred guppies, all of which are very drab in coloration at the beginning of the test.
In the same pool you've placed about 30 rivulus, one of the least voracious of all
guppy predators. These predator fish, which typically occupy the highest reaches of
guppy streams, generally eat only young guppies and do not distinguish between males
and females.
Guppy Color Types: Mostly drab
Predator Species and Numbers: 30 rivulus
