What causes variations in organisms?

Back

Mutations are the primary cause of variations in organisms.

Front

What is the term for differences in traits within a species?

Back

Variation refers to the differences in traits among individuals of the same species.

Front

What is the process called when traits change over time in a population?

Back

Evolution is the change in traits over time in a population.

Front

Why are mutations important for evolution?

Back

Mutations provide genetic variation that is necessary for a population to evolve.

Front

What is the process where organisms survive or die based on their adaptations?

Back

Natural Selection is the process where organisms live or die based on their adaptations to their environment.

Front

What is the definition of natural selection?

Back

Natural Selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What role does genetic variation play in evolution?

Back

Genetic variation is essential for evolution as it provides the raw material for natural selection to act upon.

Front

What is an example of a trait that can vary within a species?

Back

Wing color in moths is an example of a trait that can vary within a species.

Front

How does natural selection lead to evolution?

Back

Natural selection leads to evolution by favoring individuals with advantageous traits, allowing them to reproduce and pass those traits to the next generation.

Front

What is the relationship between mutations and adaptations?

Back

Mutations can lead to adaptations, which are traits that improve an organism's ability to survive and reproduce in its environment.
