What is the significance of variations among organisms?

Back

Variations among organisms are important for natural selection, as they provide the raw material for evolution.

Front

What is the role of competition in natural selection?

Back

Competition among organisms for resources leads to the survival of the fittest, where only the best-adapted individuals reproduce.
