4 components of natural selection

Natural Selection in a Nutshell: Natural selection is the process by which individuals better adapted to their environments survive longer and reproduce more. Natural selection acts on phenotypes, or physical traits, that confer an advantage in fitness at the individual level, thus altering allele frequencies at the population level.

Darwin’s process of natural selection has four components. Variation. Organisms (within populations) exhibit individual variation in appearance and behavior. …Darwin's theory consisted of two main points; 1) diverse groups of animals evolve from one or a few common ancestors; 2) the mechanism by which this evolution takes place is natural selection.

Variation: Organism (within populations) inherited individual diversity in appearance, and behavior is inherited by organisms (within populations).

Natural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift. Darwin's grand idea of evolution by natural selection is relatively simple but often misunderstood. To see how it works, imagine a population of beetles: There is variation in traits. For example, some beetles are green and some areVISTA. 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. Windows are an essential feature of any home, providing natural light, ventilation, and a view of the outside world. However, like any other component of your house, windows have a lifespan and may eventually need replacement.Natural selection. Finally, the most famous mechanism of evolution! Natural selection occurs when one allele (or combination of alleles of different genes) makes an organism more or less fit, that is, able to survive and reproduce in a given environment. If an allele reduces fitness, its frequency will tend to drop from one generation to the next. Natural selection is the idea that organisms that are best suited to survive pass their traits down.

Fitness (biology) Fitness (often denoted or ω in population genetics models) is the quantitative representation of individual reproductive success.
