Evidence for Evolution Test! Trivia Quiz

1. What can you conclude based on this drawing?

Fossils in layer Q are younger than layer H

Fossils in layer Q are older than layer H

Fossils in layer J are older than layer I

Fills in layer P are younger than layer K

The fossils at the bottom will be older than the fossils at the top

Explanation

The fossils at the bottom will be older than the fossils at the top

2. These limbs provide evidence of common ancestry because they

Have the same basic structure

Perform the same function

Are the same size

Are parts of mammals

The fact that these limbs have the same basic structure suggests a common ancestry because it indicates that they share a common evolutionary origin. This similarity in structure implies that they were inherited from a common ancestor and have been modified over time to suit the specific needs and functions of different organisms. The presence of this shared characteristic across different species supports the idea that they all descended from a common ancestor with similar limb structures.

3. The presence of wings in bats, birds, and insects is an example of a(n):

Homologous structure

Vestigial structure

Karyotype structure

Analogous structure

This is an analogous structure because they have different structures (different ancestors), but the same function

Explanation

This is an analogous structure because they have different structures (different ancestors), but the same function

4. Why are these considered analogous structures, not homologous structures?

They have the same structure but a different purpose

Even though they have the same structure, they did not have a common ancestor with that structure

They have completely different structures and purposes

They have a common ancestor with the same trait

The correct answer is that even though the structures have the same form, they did not evolve from a common ancestor with that structure. This means that the similarity in structure is not due to shared ancestry, but rather due to convergent evolution, where different species independently evolve similar traits in response to similar environmental pressures. Therefore, these structures are considered analogous rather than homologous.

Explanation

The correct answer is that even though the structures have the same form, they did not evolve from a common ancestor with that structure. This means that the similarity in structure is not due to shared ancestry, but rather due to convergent evolution, where different species independently evolve similar traits in response to similar environmental pressures. Therefore, these structures are considered analogous rather than homologous.

5. Which layers of rock would have fossils that are older than the fossils in layer C?

Layer A

Layer F

Layer G

Layer E

Fossils found in layers of rock are typically older as we move deeper into the Earth's crust. In this case, since layer C is mentioned as a reference point, both layer F and layer G would have fossils that are older than those found in layer C. Therefore, layer F and layer G are the correct answers.
