Live simulation: each grazer's colour shows its top speed, slower to faster

EvoEco Studio

Evolution, simulated.

We build little worlds, let evolution run, and show you what happens. Then you get to play with the same world.

Experiment 01

Two islands. One difference.

Same grass, same founders, same starting speed. One island has predators. We let forty generations go by and watch what happens to the animals that have nothing to run from.

Two islands side by side: grazers share the left island with purple predators; the right island has grazers only.

How it works

Nothing is scripted.

Every creature carries genes. Offspring copy them with tiny mistakes. The world decides who gets to have offspring. That's all evolution needs, and it's all we give it.

  1. 1

    Ask a question

    Each episode starts from a real question in biology, often a famous study.

  2. 2

    Run the experiment

    We build a world where evolution actually happens, then watch what it does.

  3. 3

    Play it yourself

    Every experiment gets a playable version here, so you can change the rules and try again.

Real simulationsThe footage of every experiment is the simulation itself, not stock clips.
