When it spots its prey, it spreads its wings and glides down to attack.What are the three main causes of evolution? What is the first step of evolution? 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.
