CHRIS HAY / THE NOTEBOOK / CELL80

A world that can
be questioned.

Three questions asked of a small evolutionary world: what changed its history, what keeps it alive, and whether one advance can make another possible.

Personal experiments around established artificial-life questions. Follow the recorded interventions, read the limits, and see what remains open.

    REPLAY THE WORLD

    Can you name the mutation that changed a world?

    One birth changes two inherited fields. Undo only the reproduction-program change, then examine the recorded outcome.

    One birth.
    Two histories.

    KEEP IT ALIVE

    What keeps an evolving world alive?

    Program variation sustains predators and grazers in the tested conditions. Survival and a detected arms race remain separate claims.

    Still alive.
    Still a question.

    SURVIVAL ≠ COEVOLUTION

    ASK WHAT IT CAN BUILD

    When does improvement become invention?

    Useful changes, distinct behaviours and two sequential improvements. The held-out dependence gate remains unpassed.

    THE RATCHET / OPEN

BUILDING THINGS TO FIND OUT HOW THEY WORK

A small executable world. A deep old question.

Artificial life has explored digital organisms, coevolution and cumulative adaptation for decades. These notes follow my own experiments within that tradition, from an inspectable birth to a result I cannot yet claim.
