Explanation:
Detailed explanation-1: -Natural selection cannot act on variation that is due purely to environmental conditions. In reality, variation among organisms often is the result of a combination of environmental and heritable causes, as illustrated by the variation in height among humans.
Detailed explanation-2: -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.
