This simulation can be used to study the effect of environment on natural selection. A predator eats a prey organism with two possible phenotypes; brown and gray. You will play the part of the predator. "Eat" as many prey as you can in the time available by clicking on them. You can choose from three different environments. Select the environment, then click "Run Simulation" to start.
At the begining on the simulation the prey population is a roughly even split of brown and gray. The simulation starts with 50 prey organisms and each is randomly assigned a phenotype, with a 50% of the organism being either color. After the simulation has run, you will be given the starting and ending percentages for gray and brown individuals in the prey population.
