How is natural selection used in everyday life?
During rainy times, more small seeds were produced and the finches with smaller beaks fared better. Since the environment supports both types of beaks, both remain in the population. Peacock females pick their mate according to the male's tail.
What are the 5 principles of natural selection?
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.
What is natural selection in your own words?
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
What is the main purpose of natural selection?
Natural selection enhances the preservation of a group of organisms that are best adjusted to the physical and biological conditions of their environment and may also result in their improvement in some cases.
