  We model evolution of plants in a world, made up of different locations, with
multiple environments (mutually exclusive and collectively exhaustive subsets
of locations). Each environment (landmass) has temperature, rainfall, and other
attributes that directly affect plant growth and reproduction. Each plant has
preferences for environment attributes. Depending on how suitable the
environment is to the plants, seeds are released or death occurs. With every
reproductive cycle, genetic mutations occur. To model competition, plants in
compete for survival, and success is stochastically dependent on environmental
fitness. Our model determines whether and how evolution occurs, and how the
attributes of plants change and possibly converge over time in relation to the
attributes of the environment.
