Variations in organisms lead to diversity in living organisms? State reasons (AS1)

Yes variation in organisms lead to diversity in living organisms. 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 increased, leading to variation in moth to become more prevalent over the course of around 50 years. Therefore, the population of black moth increased and white when down. This shows that variation caused a new diversity in moth. Thus, variation occurs in organisms due to various reasons like environmental factors, climate, survivalist etc. Variation thus caused leads to diversity in living beings.
