Review Evidence of Evolution

Front

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

Back

Analogous structure

Front

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?

Back

Homologous structures

Front

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

Back

Distantly related they are.

Front

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

• The organisms probably use their forelimbs for the same thing.
• The organisms evolved from a common ancestor.
• The organisms have the same DNA.
• All vertebrate species have identical forelimbs.

Back

The organisms evolved from a common ancestor.

Which conclusions are best supported by the embryo diagram?

• Organisms that share a common ancestor develop differently through the three phases of development.
• Organisms appear similar in early development because they share a common ancestor.
• Organisms that are more closely related develop faster than other organisms due to sharing a common ancestor.
• Organisms develop at similar rates because they share a common ancestor.

Back

Organisms appear similar in early development because they share a common ancestor.

The appendix, tailbone, and wisdom teeth are all examples of what type of structure in humans?

According to this data, the unknown bacterial species is most closely related to: Species I, Species II, Species III, Species IV

Species IV

Front

Homologous structures are a result of: convergent evolution, divergent evolution, coevolution, artificial selection

Back

divergent evolution

Front

Analogous structures are a result of:
- convergent evolution
- divergent evolution
- coevolution
- gradualism
