If an organism has a vestigial structure, that structure likely once had a function in a(n)

• early ancestor
• unrelated organism
• embryological stage

Farmers and breeders allowed only the plants and animals with desirable characteristics to reproduce, causing the evolution of farm stock. This is an example of ?

• Natural Selection

• Oscillating Selection

• Artificial Selection/Selective Breeding

• None of the above

The white feathers of a snowy owl allow it to blend in with its environment during the winter months (snow). This is an example of ________________

• Species
• Environmental Change
• Adaptation
• Variation

The similarities of the bones in the diagram provide evidence that---

• The organisms shown lived in the same natural envionrment

• The organisms shown developed from a common ancestor

• The organisms shown have the same genetic diseases

• All vertebrate species have identical forelimbs

Certain insects resemble (look like) the bark of the trees on which they live. Which statement provides the best explanation for this resemblance?

• The trees caused mutations in the insects

• Natural selection played a role in this protective coloration

• The insect needed better camouflage so the insects caused this coloration
