Front

What role does competition play in natural selection?

Back

Competition for resources among organisms leads to the survival of those best adapted to their environment.

Front

What is the significance of variation in a population?

Back

Variation in a population is crucial for natural selection, as it provides the raw material for evolution.

Front

What is the difference between artificial selection and natural selection?

Back

Artificial selection is the process by which humans breed organisms for desired traits, while natural selection occurs without human intervention.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence of an organism, which can lead to new traits.
