I learned in the fish pong genetics virtual lab that very slight changes in things like migration rate, or mortality rate can completely change the population and the next generations. When I made the migration rate plus one, it changed everything, the graph, the population, and mortality rate. In any community, very slight changes will change the whole community forever. I tested things such as putting the mortality rate really low, and migration rate high and the rate of generations almost tripled. Things like changing the rate of fitness can also change the whole community. Overall, I learned how fragile a community really is because very small changes will change it forever.
