Biology is the most algorithm-rich science. Every biological process — flocking, foraging, evolution, molecular recognition — has been modelled computationally, and those models make excellent browser simulations because they're inherently visual and inherently interesting to non-specialists.
The Life Category — Emergent Behaviour
These simulations show how macro behaviour (a flock, a plague, a pattern) emerges from micro rules (each bird, each infected person, each cell).
The Genetics Category — Evolution
Three simulations model heredity, selection, and evolutionary dynamics.
Molecular Biology — Cells & Proteins
The Algorithms Behind Life
The biology category collectively uses more algorithms than any other category on the site:
Recommended learning path: Game of Life → Boids → Reaction- Diffusion → Epidemic SIR → Natural Selection. Each step adds a layer of complexity: discrete → continuous agents → chemistry → network effects → evolutionary dynamics.
