NOTEBOOK / 6 OCTOBER 2026
Start by watching.
My first project on Obsidian is a world small enough to inspect and cheap
enough to run many times. The appeal is in discovering what my own rules imply.
01. The feast does not last
The starting world has abundant food. By tick 100, the population has grown
from 160 to 5,168. By tick 200, it has fallen to 3,780. The initial reserve is
gone; organisms now live on what the world can replenish.
02. Crowding changes the question
By the end, 6,139 of 6,144 cells hold organisms. The original idea included
wandering and seasonal migration, but my rules produced a nearly packed field.
That changes the opportunities available to movement and sensing.
Working hypothesis
When most neighbors are occupied,
costly movement and sensing offer fewer benefits. Selection may favor cheaper
organisms that persist in place. I have not yet separated this effect from
which starting lineages happened to survive. |
03. Next experiments
- Make room. Reduce food regrowth or add periodic clearings. Does a
less crowded world retain movement and sensing?
- Freeze inheritance. Turn mutations off and compare with the same
starting conditions. How much change comes from sorting initial traits?
- Repeat. Run a set of seeds and compare distributions, rather than
treating this one history as a general result.
A rule for this notebook
Keep the observation, explanation, and next test distinct. Save the seed,
source, and measurements so an appealing story can be checked.
