A bat wing and a butterfly wing are both used for flying but they are made differently. What type of structure is this?

• Homologous structure

• Analogous structure

• Vestigial structure

• Fossil structure

A human arm and a whale fin have similar bone structure but the whale fin is used for swimming and the arm is used for reaching and grabbing. What type of structures are these?

• Homologous structures

• Analogous structures

• Vestigial structures

• Fossil structures

When comparing the DNA of two different organisms, the more differences in the DNA base pairs the more-

• Closely related they are.

• Distantly related they are.

• It doesn't prove anything.

• They look alike.

Which of the pictures above would be examples of homologous structures? (pick 2)

• 1

• 2

• 3

What type of evidence is shown with the diagram above?

• Molecular

• Anatomical

• Embryological

• Fossil

How do fossils provide evidence that evolution has happened on Earth?

• Fossils show how the sizes of certain animals has changed drastically over millions of years
• Fossils show that some species have gone extinct
• Fossils show how life forms present today are different than those from the past
• Different sedimentary rock layers provide evidence for how the environment has changed over time

The opossum and kangaroo both incubate their young in a pouch. This provides evidence that they---

• are descended from a common ancestor
• Have very similar skeletal structures
• belong to the same species
• must range great distances to eat

Sharks and dolphins both have streamlined bodies that allow them to move through water efficiently, this is an example of which type of evolution?

• Divergent
• Coevolution
• Convergent
• Artificial

What type of evolution is the following:
The Galapagos tortoises share a common ancestor, but they have different neck lengths to help them in their environment.

• Divergent Evolution
• Convergent Evolution
• Co-Evolution
• Punctuated Equilibrium

What type of evolution is the following:
Ants are the correct size and weight needed to open the flowers of the peony plant. The peony plant provides food for the ant and the ant fertilizes the peony's flowers.

• Divergent Evolution
• Convergent Evolution
• Co-Evolution
• Punctuated Equilibrium
