Explore how organisms with different traits survive various selection agents within the environment.
An interactive simulation that explores how different traits in organisms affect their survival within the environment.
Natural Selection - PhET Interactive Simulations
This model simulates the classic example of natural selection on color patterns in peppered moths (Biston betularia). When air pollution is low, lichens cover the trees and the light moths are well camouflaged.

Natural Selection on a Diallelic Locus. This module simulates the deterministic process of natural selection acting on the three genotypes present at a one locus with two alleles. The module displays the results of natural selection on four plots: genotype frequency over time, frequency of the A allele over time, population mean fitness (w-bar ...
Explore natural selection by controlling the environment and causing mutations in bunnies. Version 1.03.
Discover how natural selection works with this interactive simulation. You can manipulate the environment, traits and mutations of bunnies and wolves and observe how they evolve over generations. This simulation is part of the PhET project, a free online resource for STEM education.
In this simulation you will look at the evolution of two traits, camouflage in a prey population and visual acuity in predators. Each individual within a population has a number that indicates the effectiveness of its camouflage (if it is a prey) or vision (if it is a predator).
Do you want to learn about natural selection in a fun and interactive way? Try this web lab that simulates the evolution of peppered moths in different environments. You can change the pollution level, the bird's vision, and the moth's mutation rate and see how they affect the population over time. This web lab is designed by EDC, a global nonprofit organization that creates learning ...
