Front

What is natural selection?

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is selective breeding?

Back

Selective breeding is a process used by humans to develop new organisms with desirable characteristics.

Front

Give an example of selective breeding.

Back

Cross breeding a labrador retriever with a poodle is an example of selective breeding.

Front

Who decides which traits should be passed on in natural selection?

Back

Nature decides which traits should be passed on in natural selection.

Front

What are the differences among a species called?

Back

The differences among a species, like different bird beaks, are called variation.

Front

What is the role of variation in natural selection?

Back

Variation provides the differences in traits that can be selected for or against in natural selection.

Front

How does selective breeding differ from natural selection?

Back

Selective breeding is controlled by humans, while natural selection is driven by environmental factors.

Front

What is an example of a trait that might be favored by natural selection?

Back

A trait that might be favored by natural selection is a thicker fur coat in animals living in cold climates.

Front

What is the significance of genetic variation in a population?

Back

Genetic variation is important for a population's ability to adapt to changing environments.

Front

What is the main goal of selective breeding?

Back

The main goal of selective breeding is to produce organisms with specific desirable traits.
