Use this infographic to explore how Darwinism and genetics came together to explain what we know today about evolution.

Detailed explanation-3: -Natural selection is a simple mechanism that causes populations of living things to change over time. In fact, it is so simple that it can be broken down into five basic steps, abbreviated here as VISTA: Variation, Inheritance, Selection, Time and Adaptation.
