🧬 Understanding Evolution Through Probability

This worksheet helps students investigate how probability and chance events shape evolutionary outcomes. Learners explore how genetic variation, random mutations, and inheritance patterns influence which traits become more common in a population over time. By analyzing scenarios involving likelihood, selection, and variation, students develop a deeper understanding of how evolution is not directed, but driven by probabilistic processes. This resource fits seamlessly into genetics, evolution, and population biology units.
