Natural Selection with Teddy Grahams: A Comprehensive Guide to the Evolutionary Lab

"The Teddy Grahams natural selection activity is a classic biology classroom simulation designed to demonstrate how environmental pressures influence the frequency of alleles and traits within a population. By using graham cracker cookies as a proxy for a prey species—typically identified by their shape, such as bears—students simulate multiple generations of survival, reproduction, and trait distribution based on environmental conditions. Understanding the Evolutionary Simulation At its core, the natural selection simulation using Teddy Grahams serves as a hands-on introduction to the mechanisms of evolution as proposed by Charles Darwin.
