yuuretsu/evolution-of-artificial-life ? reverse-engineered prompt

Build me an interactive artificial life simulator where I can watch simple virtual organisms evolve over time in a living ecosystem.

I want the whole thing to feel like a playful science demo, with agents moving around, eating, reproducing, competing, and changing as generations pass. Include a gene editor so I can tweak traits and see how that affects behavior, plus a few different viewing modes so I can inspect what is happening in the simulation. It should be visually clear and satisfying, with plants turning green when they photosynthesize and aggressive organisms standing out in red when they attack.

Make it easy to run in the browser, and give it a polished demo feel like a small interactive game. If you need to look up current docs online while building it, feel free to do that.
