Review Evidence of Evolution

Which of the following best describes the evidence provided by homologous, analogous, and vestigial structures in the study of evolution?

• They prove that evolution does not occur

• They suggest that all organisms have evolved in isolation

• They indicate that environmental challenges have no impact on evolution

• They provide evidence for the relationships between ancient species and current ones

What are analogous structures?

• Remnants of organs that are no longer useful

• Organs that are essential for survival

• Organs with similar functions and origins

• Body parts that serve similar functions but have different origins and structures

What do homologous structures indicate?

• A common evolutionary ancestry

• Organisms independently evolved similar solutions

• Organisms have not evolved

• A recent mutation in the species

What type of boundary is associated with the creation of new oceanic crust?

• Convergent boundary

• Divergent boundary

• Transform boundary

How do homologous structures differ from analogous structures?

• Homologous structures are more common in animals than plants, while analogous structures are more common in plants

• There is no difference between homologous and analogous structures

• Homologous structures have different functions but similar origins, while analogous structures have similar functions but different origins

• Homologous structures indicate recent evolution, while analogous structures do not

What does the similarity in the bone structure of the forelimbs of humans, bats, whales, and cats suggest?

• These species have not evolved

• These species are the strongest

• These species share a common evolutionary ancestry

• These species developed their limbs independently

Where would the youngest fossils be located

• A

• B

• C

• D

Name the reproductive barrier:

Birds in an area attract mates by offering gifts to the females.  One group of birds offers food gifts, like worms.  Another group generally offers colored objects for decorating nests.

• Temporal

• Geographical

• Behavioral

Where do ocean ridges most often form?

• At a divergent boundary

• At a convergent boundary

• At a transform boundary

What type of barrier inhibits the eastern and western skunks that reproduce at different times of the year (different seasons)?

• behavioral isolation

• ecological isolation

• habitat isolation

• temporal isolation
