• Vestigial structures

• Analogous structures

• Mutated structures

The presence of tiny, non-functional leg bones in modern whales suggests that:

• These bones have no evolutionary significance

• Whales evolved from ancestors with legs

• Whales need these bones to swim

• Whales have always been aquatic

A bat's wing and a whale's flipper are considered:

• Homologous structures

• Analogous structures

• Vestigial structures

• Identical structures

Which of the following is an example of an analogous structure?

• Human arm and whale flipper

• Bird wing and insect wing

• Snake tongue and dog nose

• Human appendix and chimp appendix

The appendix in humans is considered vestigial because:

• It helps with digestion

• It is a recent evolutionary development

• It no longer has a significant function but had one in ancestors

• It assists in respiration
