Eat Prey Live


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 the traits that individual possess.

In Eat Prey Live, players take on the role of a predator that hunts dots. The dots vary in speed and agility. As they play, students learn about how selection functions, and how populations change through time.


Eat Prey Live is designed to be used as an experiment. Before playing the game, teachers can lead a discussion and the class can design different experiments that groups will perform. At the end, students can compare their results and have a discussion over which factors affected how their population evolved.


Teachers and students can download their data and perform further analyses on them, exploring simple statistics such as means, medians and modes, or more complex statistics such as calculating the strength and direction of linear and non-linear selection.
