In the previous segment, we learnt about Cell division. In this segment, we will learn about Variation and natural selection.

What are the Variations?

The variations are the differences between the characteristics of the parent and the offspring. Variations can be due to changes in the genetic material during replication.

What is the Importance of variations?

Drastic variations can be harmful to the survival of the species. But mild variations can help a species survive the changing environment.

What is Natural selection?

Natural selection is the process through which various organisms chose certain physical characteristics in opposition to others to survive the change in surroundings.
