The similarity in bone structure and arrangement between cats and bats suggest that:

• Bats originated from bird-like ancestors

• Bats originated from four-legged ancestors, such as cats

• Modern bats fly much faster than ancient bat species

• Cats evolved from bat-like flying ancestors

The similarity in bone structure and arrangement between humans and whales is an example of:

• homology

• analogy

• convergent evolution

• metastasis

The similarity between butterfly and bat wings is an example of:

• analogy

• homology

• metastasis

• disruptive evolution

Ancient photosynthetic prokaryotes were very important in the history of life because they:

• produced oxygen in the atmosphere

• are the oldest-known archaea

• were the first multicellular organisms

• showed that life could evolve around deep-sea vents

Adaptive radiations may occur following all of these except:

• mass extinctions

• colonization of a new land mass

• gradual change in climate

• dramatically new adaptation

Stromatolites are fossils that:

• are transitional between other organisms

• are formed by early prokaryotes

• are formed by plants

• are formed by dinosaur feces

Life may have evolved through 4 stages. Put these stages into order:

A) Protocells occur

B) Polymerization occurs

C) Abiotic synthesis occurs

D) Self-replicating molecules occur

• C, B, A, D

• A, B, C, D

• B, D, A, C

• D, C, B, A

Which of the following are current scientifically-accepted hypotheses about the origin of organic molecules? (Select all that apply)

• Meteorites carry first organic molecules to Earth

• Early atmosphere reacted under volcanic conditions making first organic molecules

• Early atmosphere reacted under deep-sea vent conditions making first organic molecules
