How does natural selection work step by step?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.
How and why does natural selection happen?Natural selection occurs when individuals with certain genotypes are more likely than individuals with other genotypes to survive and reproduce, and thus to pass on their alleles to the next generation.
What are the 4 steps of natural selection?Darwin's process of natural selection has four components.. 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.. How does natural selection work in a population?Organisms with heritable (genetically determined) features that help them survive and reproduce in a particular environment tend to leave more offspring than their peers. If this continues over generations, the heritable features that aid survival and reproduction will become more and more common in the population.
