Developed by the University of Colorado Boulder, the PhET Natural Selection simulation is designed to provide a hands-on learning experience to elucidate how evolutionary forces act on populations. The simulation models a simplified ecosystem where users can manipulate variables such as genetic traits, mutation rates, and environmental pressures to observe their effects on a population’s evolution over generations.
Analytical Examination of the Simulation’s Design
The simulation strategically abstracts and distills evolutionary processes to highlight causal relationships. By focusing on visual traits like coloration and the presence of predators or food sources, it concretizes the concept of fitness and reproductive success. However, this simplification, while pedagogically beneficial, may omit complexities such as genetic drift, gene flow, and epigenetic factors, potentially limiting the scope of learning.

Theoretical Foundations of Natural Selection
Natural selection, a cornerstone of evolutionary biology, was first articulated by Charles Darwin in his seminal work, 'On the Origin of Species.'
