Unit 2.2 Evidence of Evolution

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.

The similarities of bone structure in the diagram provide evidence of what?

• The organisms probably use there forelimbs for the same thing.

• The organisms evolved from a common ancestor.

• The organisms have the same DNA.

• All vertebrate species have identical forelimbs.

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
