Eat Prey Live app for iPhone and iPad

Populations change over time, and one of the strongest forces shaping populations is predation. As predators hunt prey they remove certain individuals, and as a consequence, the genes that encode that individual are removed from the population.

In Eat Prey Live, players take the role of a predator that hunts dots. Players start by creating a population and then the hunt begins. The dots vary in speed and manoeuvrability and hunting them changes the traits of the future population. While playing Eat Prey Live, layers learn about how selection functions, and how populations change through time.

You can expand the experiment by altering your starting population. Set the speed and manoeuvrability, a trade-off between size and manoeuvrability, size of the waves, an energetic cost of hunting, and the benefit gained from a kill.
