This project simulates evolution with health. Each dot has its own health variable. Every one in 10 steps, it creates a clone of itself with its initial health, plus or minus 5. Every step, health goes down by 1. When a dot creates a clone, its health also goes down by 1. The top variable is population, and the bottom variable is the health of the most recently created dot.
Scratch can't have over 301 clones, which can cause some problems. This is my remix of Firedrake969's project. I made a lot of bug fixes and changes to make it more realistic. How it works (from Firedrake 969): Those that have low health die before they can reproduce/clone, and those that have high health clone many times. Therefore, those with high health pass on genes.
