DOK Level 1: Recall

Explain how the fossil record provides evidence for the theory of evolution.

• Fossils show that species have remained unchanged over time.

• Fossils provide a chronological record of species that have existed.

• Fossils are only found in certain types of rock.

• Fossils are not reliable for studying evolution.

DOK Level 2: Skill/Concept

Describe the process of natural selection and how it leads to evolution.

• Natural selection is a random process that does not affect evolution.

• Natural selection involves organisms with favorable traits reproducing more successfully.

• Natural selection is the process by which organisms choose their mates.

• Natural selection only occurs in plants.

DOK Level 2: Skill/Concept

Analyze the impact of the Permian-Triassic extinction event on Earth's biodiversity.

• It had no significant impact on biodiversity.

• It led to the extinction of approximately 90% of marine species and 70% of terrestrial species.

• It caused the extinction of only a few species.

• It resulted in the dominance of mammals.

DOK Level 3: Strategic Thinking

Evaluate the significance of the Cambrian Explosion in the context of biological history.

• It marked the beginning of the Precambrian era.

• It was a period of rapid diversification of life forms.

• It was a time when dinosaurs first appeared.

• It had no significant impact on the evolution of life.

DOK Level 3: Strategic Thinking

What is the main difference between relative dating and absolute dating in geology?

• Relative dating determines the exact age of a rock, while absolute dating places rocks in a sequence.

• Relative dating places rocks in a sequence, while absolute dating determines the exact age of a rock.

• Relative dating uses radioactive isotopes, while absolute dating uses the position of rocks.

• Relative dating is more accurate than absolute dating.

DOK Level 1: Recall

Which of the following best describes the concept of "punctuated equilibrium" in evolutionary biology?

• Evolution occurs at a constant, slow pace.

• Evolution is characterized by long periods of stability interrupted by brief periods of rapid change.

• Evolution is driven solely by natural disasters.

• Evolution does not occur in a predictable pattern.

DOK Level 2: Skill/Concept

Discuss the role of mass extinctions in shaping the course of biological evolution on Earth.

• Mass extinctions have no significant impact on evolution.

• Mass extinctions eliminate all life forms, leading to a restart of evolution.

• Mass extinctions create opportunities for the evolution of new species by eliminating dominant groups.

• Mass extinctions only affect marine life.
