Natural selection has no 'steps'. It is a continous process of filtering. However, there are a couple of key factors in natural selection, prerequisites that have to be met for natural selection to occur:
Overproduction-many organisms are produced
Genetic Variation-some organisms have different genetic traits than others
Struggle to Survive or Survival of the Fittest-The organisms with the traits better suited for their environment live while others die off
Successful Reproduction-The living organisms produce giving their offspring better traits to survive.
This process goes on changing a whole species. It is a big part of evolution. This helps organisms become the best suited to their environment that they can.

∙ 14y agoThe four rules necessary for natural selection to occur are:
1) The Potential for Reproduction - Species must be able to mate.
2) Limited Resources - Species have to be in competition for food, water, or shelter.
3) Individual Variation - There must be slight variation between individuals (eye color, fur thickness, size, etc.)
4) Differential Survival - Slight variation must cause more efficient reproduction (The individuals who can outperform in competition for survival have more time to mate, and mate in higher numbers)

What are the phases of Natural Selection?
The four stages are: Overproduction, Genetic Variation, Struggle to Survive, and Successful Reproduction
What are four forces that can change the frequency of genes in a population?
- natural selection - sexual selection - genetic drift - immigration/emagration
Adaptation which allows for natural selection is called?
Adaptation does not allow for natural selection: natural selection causes adaptation.
How does genetic variation support Natural Selection?
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
What are four requirements for natural selection?
Natural selection occurs when four conditions are met: 1. There is variation among individuals. 2. That variation is at least partially heritable. 3. That variation is linked to differential reproductive success. 4. More individuals are born than can survive and reproduce.

What are the four parts of natural selection of a cat?
The question is semantically equivalent to asking 'What are the four parts of the existence of a banana?' I cannot answer it.
Which is not one of darwins four main ideas of natural selection?
Abiogenesis, or more commonly known as the origin of life itself, is not part of Darwin's theory of evolution.
What process in which organisims with traits well suited to an environment are more likely to survive and to produce offspring is?
natural selection
Adaptation which allows for natural selection is called?
Adaptation does not allow for natural selection: natural selection causes adaptation.
