Theory of Evolution

Which best explains the separate evolution of African and Asianelephants?

• volcanic activity
• splitting of Pangaea 
• extinction of dinosaurs

Which can best be concluded from this information?

• The animals share a similar ancestor 
• The animals live in the same habitat.
• The animals are the same size and shape.
• The animals use the same method of movement. 

Which of these characteristics best helps scientists classify organisms?

• size
• color
• gender 
• structure 

Evolution can best be described as which type of change?

• absolute change
• gradual change 
• extreme change

Which best supports the idea of continental drift?

• Coastlines are constantly changing shape due to erosion.
• Earthquakes are frequently felt in many regions of the world
• Glaciers in areas considered too warm for glaciers to form
• Fossils of the same organism are found on differentcontinents 

Which best describes the similar function of wings in birds and butterflies?

• embryological structures
• homologous structures
• analogous structures
• vestigial structures

What can be inferred from observed similarities in the forelimbs of humans, dogs and bats?

• Bats evolved from humans
• Dogs evolved from humans.
• These organisms share a common ancestor
• These organisms are classified as the same species.

Which best explains the gaps in the evolutionary history of Earth’s life forms?

• Environmental changes prevented the formation of fossils.
• Many organisms died without leaving behind fossil remains.
• Extinct organisms did not form fossils.

Which is most likely to be related to a human based upon similar anatomical structures?

• flea
• fish
• coyote
• grasshopper 

Which evidence would best support the extinction of a past species?

• the loss of a species’ habitat
• the evolution of a new species
• the disappearance of a species’ fossils
