Only when variation in the desired feature has a heritable, genetic component can natural selection lead to evolutionary change.
<h3>Why does natural selection occur?</h3>
The method through which populations of living things adapt and transform is called natural selection. The fact that each person in a population is unique in certain aspects is referred to as natural variation. Because of this difference, some people have characteristics that are more environment-appropriate than others.
<h3>What are the significance of natural selection ?</h3>
Positive qualities are passed down across generations through this process of natural selection. It is possible for natural selection to result in speciation, in which one species gives rise to a brand-new, distinctly unique species. It is a driving force behind evolution and provides some insight into the variety of life on Earth.
