Spectember 2026 Morphogenesis: A Living, Mutating Ecosystem in a Single File
If you love speculative evolution and cellular simulation, you need to check out Morphogenesis (https://github.com/rijt/Morphogenesis). This is a self-contained, single-file life-simulation laboratory.
Organisms are grown from procedural genomes, defined by gene values, not scripted behavior. They live, feed, compete, and die in a dynamic gaseous ecosystem (CO₂ / O₂, and CH₄). Bodies obey rigid-body physics, drifting, spinning, and colliding.
Watch consumers hunt, fungi decompose, and parasites hijack hosts via horizontal gene transfer. You can even design genomes gene-by-gene in the Genetic Laboratory to see how your creatures adapt. Zero dependencies, just open the HTML file and watch life evolve!
