Explanation: Variation :Natural selection, process in which an organism adapts to its environment through selectively reproducing changes in its genotype. It reduces the disorganizing effects of migration, mutation, and genetic drift by multiplying the incidence of helpful mutations, since harmful mutation carriers leave few or no offspring..VISTA. 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.The Theory of Natural Selection explains the diversity of life on Earth using a few key principles: Species, faced with a selection pressure from their environment, can either adapt or be threatened, possibly with extinction if they are completely unable to adapt. That pressure may be due to a predator or predators, or due to alterations in the ...Strategic planning is a process that helps an organization allocate its resources to capitalize on opportunities in the marketplace.
