The worlds · many jars, six questions
Every jar, and what it asks.
Every world in the lab shares one chemistry. What changes between them is how the light falls, who is planted, how the jar is divided, and in the sandboxes a rule or two. Each change is a guess about what evolution needs to get going. This page says what each world is, what it is for, and what we have seen in it so far, kept apart from what we hope.

Then plant it, and change something.
In the lab the same list sits under Plant a world, with a Browse button that opens this catalogue beside the jar. Same world, same seed number: the same history, every time.
