Variations in org
Variation occurs in organisms due to various reasons like environmental factors, climate, and survival etc. Variation caused leads to diversity in living beings.
The uniqueness of individuals is the basis of the diversity that is shown by the living organisms. In our daily life we see a variety of plants and animals in our locality. But if we go to some other places such as hills, forests or sea side we entirely find different types of animals and plants. In fact different places in different parts of the world have their own typical kinds of living beings. Thus we can say that variations in organisms lead to diversity in living organism.
FOR EXAMPLE: White peppered moth was originally white in color with light spots, to blend with soft white colored trees, later during industrial revolution, pollution has increased, pollution caused a variation in moth to become more prevalent over the course of 50 years. Therefore the population of black moth increased and white when down.
This shows that variation caused a new diversity in moth.
Reason for the diversity was survival. White moth couldn't survive in the polluted environment so a new species came up.
