Simulation of Evolution by Natural Selection

Build your own world. Let completely random cells evolve into fit and intelligent survivors.

Red dots are cells, green circles are food. Take a look at the tooltips for more information.
In the beginning you should increase the speed of the simulation, evolution takes its time.

This is a very early version and still under development. It is written in JavaScript and HTML5, so no download or installation required. Runs best in Chrome. Firefox is ok too (~1/2 speed), Internet Explorer is slow (~1/8 speed).
