Beginning of Life
Explore the transition from prebiotic chemistry to the first self-replicating protocells. BOL simulates the leading scientific hypotheses — alkaline vents, RNA world, iron-sulfur metabolism, and warm little ponds — in a physically grounded, interactive 3D environment.
Platform Capabilities
Everything you need to explore the origin of life, from molecular chemistry to protocell evolution.
Prebiotic Chemistry
27 molecule types and 27 reaction pathways model CO₂ fixation, amino acid synthesis, nucleotide assembly, and lipid formation with pH, temperature, and mineral catalysis.
Energy Systems
Four distinct energy sources drive chemistry: thermal gradients from hydrothermal vents, iron-sulfur redox reactions, UV photochemistry, and stochastic lightning discharge.
Self-Assembly
Amphiphilic molecules spontaneously form micelles and vesicles above critical concentrations. Membrane permeability, lipid accretion, and compartment isolation emerge naturally.
RNA Replication
Template-directed RNA copying with Watson-Crick base pairing, point mutations, insertions, deletions, segment duplication, and recombination drives information evolution.
Natural Selection
Protocells with catalytic RNA and peptides grow faster via osmotic influx, attract more lipids, and divide to produce daughter cells that inherit contents — Darwinian evolution emerges.
3D Environment
A spatially resolved 3D world with thermal gradients, pH maps, mineral surfaces, and periodic boundaries provides physical grounding to all molecular interactions.
Scientific Scenarios
Choose from four leading origin-of-life hypotheses, each grounded in peer-reviewed research.
Alkaline Hydrothermal Vent
Russell & Martin hypothesis — natural proton gradients across FeS membranes power protometabolism in deep-sea vent micropores.
Iron-Sulfur World
Wächtershäuser hypothesis — CO₂ fixation on pyrite (FeS₂) surfaces at hydrothermal vents drives the first metabolic cycles.
RNA World
Gilbert hypothesis — RNA molecules act as both genetic material and catalysts (ribozymes), predating DNA and protein-based life.
Warm Little Pond
Darwin / Damer & Deamer hypothesis — wet-dry cycling in terrestrial hot springs concentrates and polymerizes organics inside lipid vesicles.
Quick Start
Get running in three steps.
Choose a Scenario
Select one of the four prebiotic hypotheses from the Scenarios page, or keep the default (Warm Little Pond).
Run the Simulation
Open the Dashboard, set the number of steps, and click Start. Watch real-time charts track molecular evolution.
Explore & Analyze
Use the Microscope for 3D visualization, or run Parameter Sweeps to compare across conditions.
