When all of the organisms of a species have died it is called

• evolution
• extinction
• adaptation
• natural selection

The diagram illustrates an embryonic stage of two organisms.

Which of the following can be determined by observing the embryos shown in the diagram

• The organisms share a common ancestry.
• The organisms belong to the same genus.
• The organisms are native to the same geographic areas.
• The organisms will grow into anatomically similar adults.

What conclusion can you draw from the fact that many modern whale species have vestigial pelvic and leg bones?

• The ancestors of whales may have been land mammals

• Whales could walk if they wanted to

• Whales are preparing to evolve into land animals

• Someday whales will be able to walk and will have legs

The picture shows similarities among the forelimbs of three animals. The similarities provide evidence for which of the following hypotheses?

• Legs and wings may have evolved from flippers.

• All mammals have evolved from an ancestor that was a bat.

• A cat’s leg, a whales’sflipper, and a bat’s wing have identical functions

• Cats, whales, and bats had the same ancestor millions of years ago.
