Species Evolution Simulator

Species is less of a video game than an evolution simulation program. One can simply sit back and watch creatures adapt and speciate or one can introduce selection pressures to see what happens. Challenge yourself to evolve something resilient. Among other things, players can change the oxygen levels, temperature, sea levels, and radiation. Changes in terrain can force creatures to expend more calories in order to move. Specific attributes can be added to the gene pools of any population, including not only shape and color, but sex drive, the maximum genetic distance allowable for successful mating, and metabolism – affecting secondary traits such as how often they sleep and how much food they need to keep from going extinct. The software tracks phylogenetic history to produce cladograms and comes with a DNA toggle board. It looks awesome.
