Natural Selection Explained! - Simple definition w/ 3 examples

Natural Selection is the most widely known, but also misunderstood evolutionary force. This video provides a simple definition for selection, 3 theoretical examples, simple calculations for fitness, and how we are able to simulate selection in our evolution simulator. The evolution simulator will be used for an upcoming Evolutionary biology course, exclusive to members of the Learn Adventurously Bioclub. However, the tool itself will be freely accessible on Learn Adventurously.
