Origin-of-Life Simulator

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.

27 Reactions

Energy Systems

Four distinct energy sources drive chemistry: thermal gradients from hydrothermal vents, iron-sulfur redox reactions, UV photochemistry, and stochastic lightning discharge.

4 Energy Sources

Self-Assembly

Amphiphilic molecules spontaneously form micelles and vesicles above critical concentrations. Membrane permeability, lipid accretion, and compartment isolation emerge naturally.

Micelle → Vesicle Assembly Pathway

RNA Replication

Template-directed RNA copying with Watson-Crick base pairing, point mutations, insertions, deletions, segment duplication, and recombination drives information evolution.

6 Mutation Types

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.

Fitness-Driven Selection Pressure

3D Environment

A spatially resolved 3D world with thermal gradients, pH maps, mineral surfaces, and periodic boundaries provides physical grounding to all molecular interactions.

20³ Spatial Grid

Scientific Scenarios

Choose from four leading origin-of-life hypotheses, each grounded in peer-reviewed research.

Quick Start

Get running in three steps.

1

Choose a Scenario

Select one of the four prebiotic hypotheses from the Scenarios page, or keep the default (Warm Little Pond).

2

Run the Simulation

Open the Dashboard, set the number of steps, and click Start. Watch real-time charts track molecular evolution.

3

Explore & Analyze

Use the Microscope for 3D visualization, or run Parameter Sweeps to compare across conditions.
