The Stages of Natural Selection

Natural Selection is the process whereby animals adapt to their environment to increase their survivability. The process doesn't have “steps”. It is a continuous process of filtering. However, there are a couple of key factors in natural selection that need to be met for natural selection to occur. These stages are overproduction, variation, adaptation, and selection.


A fish may lay hundreds of eggs

but only a small number will survive


A mutation may cause

a slight curve

to develop in a fish's tail


The fish with the curved tail

will be able to swim faster and escape predators


With each generation

more fish with a curved tail will survive to reproduce

Over time, they will make up a larger part of the group
