What is natural selection easy definition?

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. Through this process of natural selection, favorable traits are transmitted through generations.

What is natural selection evolution for kids?

Evolution results from a process called natural selection. This process can happen when an individual’s genes differ in some way from the genes of others of its kind. Variations, or differences, in genes cause differences in an individual’s traits—such as how it looks, its structure, or its behavior.

What are the 5 steps of natural selection?

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.

  • What are the 4 main points of natural selection?

    – Variation. Organisms (within populations) exhibit individual variation in appearance and behavior. – Inheritance. Some traits are consistently passed on from parent to offspring. – High rate of population growth. – Differential survival and reproduction.
