Unit 4: Interim Review

Front

What is 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 is coevolution?

Back

Coevolution is the process where two or more species influence each other's evolutionary path, often seen in predator-prey relationships.

Front

What does common ancestry mean?

Back

Common ancestry refers to the idea that different species share a common ancestor from which they evolved.

Front

What is the significance of DNA similarity in organisms?

Back

The more DNA sequences two organisms have in common, the more closely related they are.

Front

What is divergent evolution?

Back

Divergent evolution occurs when two or more related species become more dissimilar over time, often due to different environmental pressures.

Front

What is convergent evolution?

Back

Convergent evolution is when unrelated species develop similar traits or adaptations due to similar environmental challenges.

Front

What is adaptive radiation?

Back

Adaptive radiation is the rapid evolution of diversely adapted species from a common ancestor in response to new environmental opportunities.

Front

What is the role of predators in natural selection?

Back

Predators can influence the population dynamics of prey species, leading to changes in traits that enhance survival.

Front

What is speciation?

Back

Speciation is the evolutionary process by which populations evolve to become distinct species.

Front

What is the importance of genetic variation?

Back

Genetic variation is crucial for a population's ability to adapt to changing environments and survive.
