Quiz about Evidence in the Fossil Record

Question 1

What can we expect as new fossils are discovered?

Accepted Answer

Some gaps in the fossil record may be filled.

Answer

Fossils will become less important.

Answer

No new information will be gained.

Answer

Accepted Answer

The emergence of early mammals.

Answer

The extinction of dinosaurs.

Answer

The dominance of reptiles.

Answer

The emergence of birds.

Question 3

What does the theory of evolution suggest about individuals within a species?

Accepted Answer

Individuals better suited to their environment are more likely to survive and reproduce.

Answer

Variation within a species has no impact on survival.

Answer

Individuals with the least variation survive the best.

Answer

Only the strongest individuals can reproduce.

Question 4

Why is tracing the lineage of species using fossil records challenging?

Accepted Answer

Due to the lack of transitional fossils.

Answer

Because all species have been discovered.

Answer

Because fossils are too abundant to study effectively.

Answer

Because DNA cannot be extracted from fossils.

Question 5

What role do characteristics play in the survival of species according to evolution theory?

Accepted Answer

A critical role in adapting to the environment.

Answer

A minor role compared to chance.

Question 10

Which of these statements explains why similar skeletal structures that have different functions provide evidence for evolution?

Accepted Answer

When two species have structures that are very similar physically, it shows that the species may have evolved from a common ancestor that also had a similar structure, which provides evidence that the species are related.

Answer

Two species with similar skeletal structures live in the same habitat, so they are related.

Answer

Closely related organisms generally have very different skeletal structures, but those structures usually perform the same function.

Answer

Structures with the same function show that two species learned to use them at the same time, which demonstrates an evolutionary relationship.
