Back

It means that the organisms best adapted to their environment are the ones that survive and reproduce.

Front

What is an adaptation?

Back

An adaptation is a trait that helps an organism survive in its environment.

Front

How do mutations contribute to natural selection?

Back

Mutations create variations in traits, which can lead to adaptations that may improve survival.

Front

What is genetic variation?

Back

Genetic variation refers to the differences in DNA among individuals within a species.

Front

Why is genetic variation important for natural selection?

Back

Genetic variation provides the raw material on which natural selection acts, allowing for adaptations.

Front

Give an example of an adaptation in predators.

Back

The sharp claws of a lion are an adaptation that improves its success as a predator.

Front

What is the role of the environment in natural selection?

Back

The environment determines which traits are advantageous for survival and reproduction.

Front

Can organisms change their traits at will?

Back

No, organisms cannot change their traits at will; adaptations occur over generations through natural selection.

Front

What happens to organisms without beneficial adaptations?

Back

Organisms without beneficial adaptations are less likely to survive and reproduce.
