CAST Review: Evolution

Front

What is a behavioral adaptation?

Back

A behavioral adaptation is a change in behavior that helps an organism survive in its environment, such as bird migration.

Front

What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and reproduce, leading to evolutionary changes over time.

Front

How does natural selection lead to evolution?

Back

Natural selection favors organisms with beneficial traits, leading to changes in the population over time.

Front

What is a harmful mutation?

Back

A harmful mutation is a change in DNA that decreases an organism's chance of survival.

Front

Which organism is likely to be killed off by natural selection?

Back

A very colorful fish living in the pond, as it may be more visible to predators.

Front

What is an example of a physical adaptation?

Back

Thick fur in polar bears helps them survive in cold environments.

Front

What role does genetic diversity play in evolution?

Back

Genetic diversity provides a variety of traits that can be beneficial for survival and reproduction in changing environments.

Front

What is the difference between natural selection and mutation?

Back

Natural selection is the process that favors beneficial traits, while mutation is a random change in DNA that can create new traits.

Front

What is extinction?

Back

Extinction is the end of an organism or a group of organisms, often due to inability to adapt to environmental changes.

Front

What is an example of a beneficial mutation?

Back

A mutation that allows a plant to grow in drought conditions, increasing its chances of survival.
